I think this is simple, but i am have no idea. I create a upper class: #import "downClass.h" @interface MyUpperClass : NSObject
and in than I create downClass *test = [[downClass alloc] init]. Than in my downClass is just a think like @interface downClass: NSObject They are not Inheritance, so [super function] don't work. My problem is I want to call a function in MyUpperClass and I am in downClass. It's a instance function (like "- (void) function", not with +) so [MyUpperClass function] will not work. The solution was use [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(function:) name:@"observer" object:nil]; to listen and [[NSNotificationCenter defaultCenter] postNotificationName:@"observer" object:nil]; to call. Do this a correct way to do? There are another way better than this? For me, this way cause problem because it's a little GOTO style and in debug make things difficult. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
