iOS Development in C# with Xamarin and Visual Studio

In the past, you may have considered Objective-C and iPhone development but the combination of a new architecture and a new programming language together may have been too much. Now with Xamarin Studio, and programming it in C#, you may find the architecture not that bad. You may end up coming back to Objective-C though Xamarin makes feasible any type of iOs programming including games. This is the first of a set of tutorials on programming iOS Apps (ie both iPhone and iPad) and eventually Android Apps in C# using Xamarin Studio. So what is Xamarin Studio? Previously known as MonoTouch Ios and MonoDroid (for Android), the Mac software is Xamarin Studio. This is an IDE that runs on Mac OS X and its pretty good. If youve used MonoDevelop, then youll be on familiar ground. Its not quite as good as Visual Studio in my opinion but thats a matter of taste and cost. Xamarin Studio is great for developing iOS Apps in C# and likely Android, though that depends on your experiences creating those. Xamarin Versions Xamarin Studio comes in four versions: Theres the free one that can create Apps for the App store but those are limited to 32Kb in size which is not a lot! The other three cost starting with the Indie version for $299. On that, you develop on the Mac and can produce Apps of any size. Next is the Business version at $999 and thats the one used for these examples. As well as Xamarin Studio on the Mac it integrates with Visual Studio so you can develop iOS/Android apps as if writing .NET C#. The clever trick is that it uses your Mac to build and debug the App using the iPhone/iPad simulator while you step through code in Visual Studio. The big version is the Enterprise edition but that wont be covered here. In all four cases you need to own a Mac and to deploy Apps in the App store needs you to pay Apple $99 each year. You can manage to offset paying that until you need it, just develop against the iPhone simulator that comes with Xcode. You have to install Xcode but its in the Mac Store and its free. The Business edition does not have a big difference, just that it is on Windows instead of the Mac with free and Indie editions, and it uses the full power of Visual Studio (and Resharper). Part of that comes down to whether you prefer to develop Nibbed or Nibless? Nibbed or Nibless Xamarin integrates into Visual Studio as a plugin that gives new menu options. But it doesnt yet come with a designer like the Xcodes Interface Builder. If you are creating all your views ( the iOS word for controls) at runtime then you can run nibless. A nib (extension .xib) is an XML file that defines the controls etc in views and links events together so when you click on a control, it invokes a method. Xamarin Studio also requires you to use Interface Builder to create nibs but at the time of writing, they have a Visual designer running on the Mac in alpha state. It will likely become available on the PC as well. Xamarin Covers the Whole iOS API The whole iOS API is pretty massive. Apple currently has 1705 documents in the iOS developer library covering all aspects of iOS development. Since they were last reviewed, the quality has improved a lot. Likewise, the iOS API from Xamarin is pretty comprehensive, though you will find yourself referring back to the Apple docs.​ Getting Started After installing Xamarin software on your Mac, create a new Solution. The project choices include iPad, iPhone, and Universal and also with Storyboards. For iPhone, you then have the choice of an Empty Project, Utility Application, Master-Detail Application, Single View application, Tabbed Application or OpenGl Application. You have similar choices for Mac and Android development. Given the lack of designer on Visual Studio, you can take the nibless (Empty Project) route. Its not that difficult but nowhere as easy to get the design looking spot on. In this case, as you are mainly dealing with square buttons, its not a worry. Architecting iOS Forms You are entering into a world described by Views and ViewControllers and these are most important concepts to understand. A ViewController (of which there are several types) controls how data is displayed and manages view and resource management tasks. The actual displaying is done by a View (well a UIView descendant). The User Interface is defined by ViewControllers working together. Well see that in action in tutorial two with a simple nibless App like this one. In the next tutorial, well look in depths at ViewControllers and develop the first complete App.

Expansion and Diversification Within a Business - 1991 Words

Opportunities for expansion and diversification Diversification is a form of corporate strategy for a company. It seeks to increase profitability through greater sales volume obtained from new products and new markets. A business strategy in which expansion is obtained by increasing the number of products in which customers can purchase from a company s store/under the company’s name. Fred Greer was able to mention how the Wrightbus Company expand within the bus manufacturing sector, this is carried out as employees continue to carry out production of the highest standard and ensure their products are of the highest quality.

Classroom Assessment in Fifth Grade Science free essay sample

A study was conducted to explore the hypothesis that performance assessments foster a more positive motivational orientation for students than supplied-response assessments which tend to truncate students’ learning strategies (Parkes Stefanou, 2003). We will write a custom essay sample on Classroom Assessment in Fifth Grade Science or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This was in response to general dissatisfaction arising from large-scale, high-stakes multiple choice testing, particularly among the older students who experienced higher levels of anxiety and mistrust with respect to standardized tests.   It partook of a cost-benefit analysis of the consequences of this particular type of assessment procedure to determine whether the positive outweighed the negative. Traditional paper and pencil tests (PP), a laboratory task format of assessment (lab), and a performance assessment (PA) were imposed on three different fifth grade science classes, particularly involving Goal Orientations to supply quantitative data.   Qualitative output was also obtained through taped interviews of the three classes.   Quantitatively, goal orientation seemed to be influenced by the type of assessment used. When paired with the qualitative data, students seemed to perform well in PP testing because they equated a good grade with competence and ability, and they believed that performing well in PP testing reflected this competency (Parkes Stefanou, 2003).   However, if receiving grades was removed from the equation, students became more receptive to PA testing and were motivated to take risks and explore actually doing science rather than just knowing science (Parkes Stefanou, 2003). One of the limitations of the study was that qualitative information was necessary to complete the picture presented by the quantitative data.   Although the study was by no means definitive as to whether or not assessment types contributed to student motivation, it clearly showed that when paired with the stakes or consequences attributed to the assessment results, it affects the students’ goal orientations.

Auditory and Visual free essay sample

If a variety of people are put through numerous trials of visual memory tests and auditory tests, then the people with better auditory memory will outnumber the people with better visual memory. Introduction Visual and auditory memory play vital roles in learning and development. They are both skills required to have throughout life. By definition, auditory memory is the ability to process information presented orally, analyze it, and store it to be recalled later. Visual memory by definition is the ability to process information presented visually, analyze it mentally, and remember it for a later time. Both of these skills are step-by-step developmental processes. They continue to grow when a person is growing themselves. Auditory memory is the ability to process information that is presented orally, analyze it mentally and store it to be remembered later. To be an auditory learner is to have a strong capacity for auditory memory. Auditory memory is also the ability to learn from instructions that were presented orally; it is an important skill that will help in life. We will write a custom essay sample on Auditory and Visual or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Auditory memory has to be one of the most important skills in learning. Some children who show a delayed grasp of language have weak auditory learning skills, they also have difficulty understanding words. Parents can test their child’s auditory memory by saying a sequence of numbers and asking the child to repeat the numbers back to them. Through exercises auditory memory skills can be developed. Children as well as adults can sharpen their auditory memory skills. Visual memory is the ability to psychologically recall visual images in the form of objects, events, or words. Students with disabilities have a serious deficiency with visual memory. Storing and retrieving previously experienced visual sensations and perceptions when stimuli that were evoked originally are no longer present are involved in visual memory. Many researchers have stated that 80% of learning takes place through the eye with visual memory. Visual memory is crucial in the aspect of learning. If a person cannot adequately reproduce a sequence of stimuli, then they may not have developed their visual memory skills. People who have difficulty with visual memory have trouble overall remembering the visual appearance of words, a letter sequence of words, and spelling. When people have trouble with visual memory can often remember the letters in a word but not the sequence. Some people with serious writing and spelling difficulties have trouble with their visual memory skills. The differences are that auditory memory works with the ears auditorally and visual memory works with the eyes visually. To be an auditory learner is to have a strong capacity for auditory memory. Visual memory is the ability to psychologically recall visual images in the form of objects, events, or words. Auditory memory has to be one of the most important skills in learning. Visual memory is crucial in the aspect of learning. When people have trouble with visual memory can often remember the letters in a word but not the sequence. Auditory memory is also the ability to learn from instructions that were presented orally. Parents can test their child’s auditory memory. Caffeine can affect memorization by increasing it. The ability to remember is a basic but important function that is critical to survival today. Memory is especially important for students who live their lives learning. Age can also affect memorization ability. Studies have shown that staying active can help stabilize memory change when it comes to aging. There are a few ways to positively affect memory change; they include physical activity, mental activity and a healthy diet. The primary factor affecting a person’s memorization change is a medical condition. There are a few medical factors that can negatively affect memory change; medical disorders, diseases, emotional problems, medication, medical changes, and a poor diet. Crossword puzzles can help positively affect memorization. Hormonal changes can affect memorization. Adults are twice as likely to lose mental capacity. Many body parts are involved in auditory and visual memory. The posterior parietal cortex is a portion of the parietal lobe in the brain. Activity in the posterior parietal cortex is extremely correlated with the information that can be stored in visual memory. This suggests that the posterior parietal cortex is vital in our visual representation of the world. It acts as a limited storage area for everything we see. Another important body part involved in visual memory are the occipital lobes. They are located at the back of the brain. They receive and process information. The lobes tend to process colors and shapes. They are responsible for identifying colors while visually memorizing objects. Body parts involved in auditory memory are slightly different. Auditory sensory memory tends to be stored in the primary auditory cortex closer to the ear of presentation. However, auditory memory involves many different brain parts. The majority of brain regions involved in auditory memory are located in the prefrontal cortex. This is where the executive control is located, and is responsible for attention control. Brain areas are actually a major factor in understanding why some ways of memorizing things work better than other ways. Visual memory tends to be the most readily available to us. When your brain receives information, it begins to decide what it and isn’t important. It also begins to store it as long-term. Neural connections become more powerful as the information is received and is connected to emotions. Neurons are nerve cells, and a pattern of connections between them forms a memory. Seeing something familiar tends to have a greater impact on the mind than hearing something familiar. The brain can form new neural pathways and alter existing connections. It is very easy to improve visual and auditory memory. If one organizes and structures the information they are trying to memorize, it will help immensely. It is important to visualize concepts to improve memory. Charts, graphs, and photos are all great things to look upon when memorizing. Numerous research studies have been done on visual and auditory memory. Much effort has been dedicated to investigating the capacity limits of memory in the brain. Steven J. Luck and Edward K. Vogel are two men from the University of Iowa who are known for their research on this topic. They sorted memory into two categories- long term and short term. These findings are foundation for all different types of memory. Experimental Procedure 1. In this experiment, number sequences will be needed for the test subjects to remember. Each number sequence should be composed of the numbers 0–9 and be seven digits long. This random number generator can be used to figure out the number sequences. http://www. random. org/nform. html 2. The experimenter should fill out the form on the generator so it has 7 integers, 1 as the smallest value, 9 as the largest value, and a format in 7 columns. Then the experimenter should hit Get Numbers and a new page will appear with 7 listed numbers at the top. To get new numbers, it is not necessary to fill out the form again, so simply click the refresh button on the browser window and a new set of random numbers appears: 3. The experimenter should write one number sequence on each index card, until the deck of cards consists of about 50 different random sequences. This deck will be used for the experiment. 4. The experimenter should find 25 random research participants, and ask each test subject to take two memory tests. Then give them the two following tests: A: To test ones visual memory, show the subject a card for 30 seconds and time with a timer. Take back the card and have the subject recite the alphabet. Then ask the subject to say what the numbers were. Write down how many numbers the subject got right. This will be the subject’s score. Record the score. B: To test ones auditory memory, read the sequence of numbers on a different card three times slowly. After the numbers have been read, have the test subject recite the alphabet. Then ask the subject to say what the numbers were. Write down how many numbers the subject got right. This will be the subject’s score. Record the score. 5. Calculate the percentage of people who received each score. Do this by first adding the total number of participants for each test, then divide the number of people receiving the score by the total number of participants in the study. Multiply the answer by 100 to get the percentage. 6. Analyze the data by making a histogram. On the left side of the graph (Y-axis), write a scale for the percentage of people from 0 to 100%. On the bottom of the graph, write a scale for the number of correct responses from 0 to 7.

Analysis essay about parental expectations Example | Topics and Well Written Essays - 1000 words

Analysis about parental expectations - Essay Example wise, as parental expectations play an essentially vital role in the performance of a child, ridiculously high expectations can result in their failure while low expectations can lead to under confidence. Maintaining too high expectations can also result in social anxiety, stress, depression and many other forms of mental illnesses. Every child has a different learning pace; it could be fast for some while it comes slower to others. Some children may be self sufficient while others could need help guidance and tutoring. It is an accepted fact that every child has a unique learning pace which can be molded and improved with encouragement. This suggests that the same amount expectations cannot be held with every child. That said, parental involvement does make for overall better performance in children than in the case of those whose parents are less involved. Although there are many sides to parenting, studies show that the greatest influence is cast by a single aspect, parental expectations, according to the Harvard Family Research Project (Harvard 2014). In order to provide a child with a healthy home environment, it is essential to love him unconditionally, irrespective of whether or not he is the brightest of the lot. Now the thing that gets in the way of this unconditional love is our sky high expectations (Hudson 2014). An explanation for why parental expectations are so affective on children is that they see themselves, for most of their childhood and even beyond, through their parents’ eyes. Consequently, if a parent believes his child can be a top-dog, that’s what his child will perceive himself to be. On the other hand, if a child has been exposed to derogatory aura at home, he is most likely to accept failure without really trying at all. Similarly, having far greater expectations from your child than his obvious abilities is like expecting a chicken to swim or a cat to fly. The key here is for parents to analyze the situation their child is in

Inventory stystems Assignment Example | Topics and Well Written Essays - 250 words

Inventory stystems - Assignment Example The system used by Kroger allows for the shelves to look like they are always full with the same type of products. This allows the products to look readily available at all times. The system works well when the projected amount of sales are accurately made. Allowing for too much or too little inventory will mean for inadequate operating costs. This is also known as order quantity issues. This can mean losing customers or allowing food to expire. Firms like Kroger that use perishable inventory are dependent on an accurate inventory. Order quantity issues can arise from any type of inventory system. This system that is used by Kroger is pretty acceptable. The only problem is that because most of the inventory is perishable, inventory accuracy must be perfect so that money is not lost. Proper management, research and production teams are essential to making sure proper inventory levels are maintained. The development of a new hybrid model can eliminate wasted inventory. Wasted inventory is a common problem for firms such as Kroger. No matter which inventory system is used, there has to be some sort of a control that allows the firm using the system to remain orderly and profitable. Without the chance for steady inventory and profit, the firm will not survive. Inman, Anthony.
