IntroducedOBJECTIVE-C has postponed many decisions from a cheap period and link period to a run-time period. Whenever possible, it does a lot of things dynamically. This means that it requires not only a compiler, but also a runtime system to
The Runtime Library is
Program The library files required during runtime. Generally, the Runtime Library is provided in the form of LIB or DLL. The C Runtime Library was born in 1970s. At that time, the program world was still very simple.
The advantage of the Objective-c language is that we are more flexible when writing code, such as we can forward the message to the object we want, or swap the implementation of a method at random. This feature means that objective-c requires not

Objective-C is a dynamic language, and many things are determined by runtime.
For example, the code first declares that testObject is an NSString, then creates an NSData Object, and saves the

Without a lot of preparations, let alone: runtime is a dynamic library written by C and sink, just like a small system that closely associates OC with C. This system mainly does two things.

There are compile-time polymorphic and run-time polymorphism in C #, Java, and only runtime polymorphism in OC, which is related to its operating mechanism. In OC, the invocation of a method is done through the delivery of the message. In the iOS
