In Objective-C, how to prevent name collision in category methods?

Question

Some people have used prefixes to name their category methods in order to prevent possible name collisions with other external code, but I personally find that adding noise to a name that is otherwise clear. Is there a better way to avoid category name collisions than prefixing it?

e.g.

@interface UILabel (Extras)
-(void)prefix_extraMethod;
@end

In Objective-C doesn't exist namespace so the only way is to prefix your method.

If don't want to prefix (I agree with you..it's ugly) you can the OBJC_PRINT_REPLACED_METHODS environment variable to YES to receive a warning if you method name collide with other existing method.
