IPhone development and learning

At the end of the year, I started a long-lost iPhone 4. I joined the icrazy family and put it to rest. Besides the stylish appearance, gorgeous interface, and heartbleed touch, we also found that there are a lot of outstanding apps on iPhone 4, open the iTunes store, a wide array of all kinds of application software, of course, most of the outstanding software is paid software. Apple's iPhone has ushered in a new era of mobile platforms, and its out-of-the-box match with App Store is also available worldwide. Program Members provide a new stage to display their talents. As long as they have novel ideas, they can develop excellent applications and put them into the App Store to realize their entrepreneurial dream, in fact, I also have a lot of good idea products that can be sent to mobile phones. This makes me have the urge to develop the iPhone. After learning about it on the Internet, the "Basic tutorial on iPhone development" is suitable for me now. I first downloaded an electronic pdf of the deleted version, I feel that this book is really good. I am going to purchase it In Shucheng in a simple way. I am afraid it is easy to use. However, it is a pity that a computer running the Apple operating system is required before writing the iPhone software. However, this is not a problem, because the Apple operating system is no longer the previous Power PC processor, the Power PC Processor uses a structure called the "RISC, the power architecture itself is different from the X86 architecture design principles adopted by Intel/AMD. Therefore, it is completely incompatible with the software. That is to say, before Apple switched to the intel camp, it was a fantasy to install Apple's operating system on a normal PC, or install Windows on an apple machine. Now, Apple's full range of computer products have adopted Intel processors in the X86 architecture, so we can easily install Windows on Apple's computer; otherwise, the Windows operating system can also run perfectly on the Apple computer, so I can download an image file of the Apple operating system and install it on my own, in this case, we need to invest a lot of money in purchasing Mac in our province. Of course, even if I can't install the Apple operating system on my PC, I won't be able to afford such expensive money for the moment. Maybe it's just like learning, it's intellectual investment, but China is still mostly poor, if the problem of food and clothing is not solved, who will think about "investing"? So this will lead to many kinds of social problems and our work will be the same, how many people actually come to work because of their own interests? I think most people sell their bodies and souls to the capitalists every day, just like me. What I get is my living condition. Why can Bill Gates succeed, I think that apart from being a genius and being born in a very suitable age, he is also a rich man because he can do anything he is interested in, even if it is not paid, or even more material conditions. Let's get down to the truth, continue to the road to my iPhone, solve the operating system problem, and download an iPhone SDK (software toolkit). Of course, this SDK is free of charge and contains a simulator, payment runs most iPhone programs on MAC (why is it the majority? The reason is that the simulator does not support hardware features, such as the accelerator or camera function of the iPhone. However, the free option does not support downloading applications to the actual iPhone, it does not support distributing applications on Apple's iPhone App Store. Two additional download options are required to implement these features. Unfortunately, they are not free of charge. The paid version is divided into two versions: the standard version and the enterprise version. The price of the standard version is $99, and applications can be downloaded to the actual iPhone and Apple's iPhone App Store for distribution, the price for the Enterprise Edition is USD 299, which allows enterprises to develop dedicated and internal iPhone applications. When these conditions are met, you can start programming. For iPhone program development, the language used is objective-C, and the tool used is cocoa touch in the SDK.
