What makes them special is that iOS runs ahead of time and automatically calls both methods, and many of the Rules for class methods (such as inheritance, category) are handled differently.Let's take a look at the two methods described in NSObject

If it weren't for Apple, it wasn't app Store,object-c. I'm afraid it's already out of sight. Most programming languages are based on the C grammar style, so the first touch of this non-C-style language, will not understand its strange grammar. But

The DLL generated on the. NET platform using the C # language is msil-Based Binary Code. Generally, it cannot be called by native languages and programs (such as VB, Vc, and Delphi ). However, native programs on Windows can directly use COM objects.

In the past, most of the methods for writing dynamic link libraries were directly implemented using the extern 'C' method. However, if classes are used for writing, problems may occur, this is because the class cannot determine the entry point

C # class variables point to the instantiation of a derived class Object 1. hierarchy (for constructors) The constructor of the class to be instantiated Cannot initialize the class, but must also call the constructor in the base class. Therefore,

C ++ class usage notesWhen we create A class, we sometimes want to initialize the class members to 0; for example, class A; we define A m_a; sometimes we will simply use memmset (& m_a, 0, sizeof (A); in this way, it seems that the m_a member is

Objective-C is a class-based object-oriented language. Each object is an instance object of a class. The isa pointer of the object points to the class corresponding to the object. Class describes the object data: memory allocation size, variable
