Differences between methods and functions

1. Method:

1. All object Methods start with minus sign-

2. Object method declaration must be written between @ interface @ end

3. The implementation of object methods must be written between @ implementation @ end

4. Object methods can only be called by objects

5. Object method category \ object all

6. Class methods all start with a plus sign +. Other rules and object methods are the same.

7. Class methods can be called either by class (Class Name) or by objects

 

2. functions:

1. functions belong to all files and have no relationship with objects. They can be written anywhere in the file (between @ interface and @ end cannot be written)

2. function calls do not depend on objects.
