Hi,
I have a code like this:
@interface BackgroundObj : NSObject
{
Controller *mc;
}
- (void) sayHi;
@implementation BackgroundObj
- (void) sayHi
{
[mc showText:@"Hi"];
}
@end
As you can see, the code is hard coded to use class Controller, can not be used with any other object, I'd like to add a delegate which will have a showText method, sayHi method will just call the delegate instead of hard coded Controller, any idea how to add delegates to this object? or, any tutorials for this? Thanks,
Angelo
