From C ++ to objective-C [from devbean's world]

The series from C ++ to objective-C is over. I would like to reiterate that this series is not a complete objective-C Teaching document, but it is convenient for developers who are familiar with C ++ or C ++ (for example, a large number of Java programmers) can quickly use objective-C for simple development. Of course, currently, objective-C is most widely used in Apple development, MacOS X, and IOS. This series only introduces the objective-C language itself, and there is not much involved in the development of the apple series. Just as you only know the C ++ syntax and don't know how many libraries can do anything, learning objective-C also has to learn more about the use of MACOs, IOS, and other libraries. This is no longer within the scope of this series. Please forgive me for this. The following is the directory of this series:
