Apple's new place of OC for a high-level programming language!
Do app using Xcode application development time，UI interface design what application is commonplace，But every time and then run the simulator to view the output of a very troublesome thing，Especially when you need to modify many elements、And the need to fit a variety of screen sizes with the time - after all,，Now iPhone product line is no longer so a single。
so，Breath simulator run three or four such things fear[……]
Since you want to learn programming，Then we should at least know their own learning is what it okay?
Speaking of programming，In fact, the earliest still have to catch up with our big brother Alan Turing God go。At that time Turing invented Turing machine - this thing is very fast hardware，Finish all had easily shortened to two years of World War II where we do not start speaking up，We say that the main，The Turing Machine，Basically it is the first computer!
of course，[……]
Now most of the high-level programming language，All evolved from the classic C language，You grammar which in these programming languages，More or less can be found in the shadow of a fraction of the C language，This is why a lot of people still recommend，From the C programming language into the language of the door。
but，C language is indeed a sufficient old，Many people are directed to write a program target learning to play the APP，You to learn C language ...... sorry，[……]
Swift recently started learning the，It is like "hello world" as，Each language seems to always have a "write Douban FM" project tutorial😶
In short，I started using this process taught to become familiar with the development process，but，Only yesterday did show playlists and display the song Cover，Today adds playback collapsed flash back!
Ok，Even the newly added[……]
In use xcode Make a program when，We generally use some pictures instead of stiff off button text，Make the interface more beautiful。
