Objective-C: Overload

In iOS, reload can be performed in two ways: 1. The number of different parameters. 2. If the number of parameters remains the same, modify the name of at least one parameter. This is a strange overload method. Even if the return type is modified, the overload cannot be implemented.

-(Nsinteger) Method1 :( nsinteger) param1 {ReturnParam1 ;}-(Nsstring *) Method1 :( nsstring *) Param1andparam2 :( nsstring*) Param2 {ReturnResult ;}

 

Well, it's also case sensitive to modify the parameter name.

-(Void) Drawcirclewithcenter :( cgpoint) paramcenter radius :( cgfloat) paramradius {}-(Void) Drawcirclewithcenter :( cgpoint) paramcenter radius :( cgfloat) paramradius {}
