Method overloading in Objective-C?

Question

hello,

as far as my knowledge, objective-C does not support method overloading.What can be the alternative for this in Objective-C? or should i always use different method name?

Answer 1

Yes, I think you'll have to always use different method names.

Answer 2

Correct, objective-C does not support method overloading, so you have to use different method names.

Note, though, that the "method name" includes the method signature keywords (the parameter names that come before the ":"s), so the following are two different methods, even though they both begin "writeToFile":

-(void) writeToFile:(NSString *)path fromInt:(int)anInt;
-(void) writeToFile:(NSString *)path fromString:(NSString *)aString;

(the names of the two methods are "writeToFile:fromInt:" and "writeToFile:fromString:").
