One. Isa pointerTo understand what Isa pointers are, we have to make a point:In objective-c, the definition of any class is an object. There is no intrinsic difference between a class and an instance (object) of a class. Any object has an Isa

PrefaceAt present, Objective-c (OC) is the core language of iOS development, in the development process will also cooperate with the use of C language, C++,OC mainly responsible for the UI interface, C, C + + can be used for graphics processing.

No matter what language we use, there is always the need to determine whether two objects are equal, OC of course is no exception. First look at a piece of code: NSString *STR1 = [[NSString alloc] initwithcstring: "equal"

In object-oriented languages such as java/c#, access to a method can be controlled through public/private/protected to control its access rights. In OC, however, the method does not have access modifiers. So do we have a way to make it private?1. If

Internal OC: Deep (copy) copy of Mutable objects and immutable objects thinking:Immutable objects: For example, the NSString object, because the NSString object is a constant string, you cannot change its contents, but you can modify the pointer
