> How can I get [self delegate] to recognize my custom methods? There are two ways, one simpleminded, the other a bit sophisticated: 1. Use a local variable: id<TKOutlineViewDelegate> delegate = [self delegate]; … [delegate outlineView:self enterKeyPressedForRow:[self selectedRow]]; … You'd need to introduce the local variable into each scope where you send the delegate one of your custom messages. 2. Redeclare the "delegate" property: @interface TKOutlineView : NSOutlineView {} @property (nonatomic,readonly) id<TKOutlineViewDelegate> delegate; @end @implementation TKOutlineView @dynamic delegate; … [[self delegate] outlineView:self enterKeyPressedForRow:[self selectedRow]]; … The @dynamic statement says "I don't have an implementation of the 'delegate' property in this class, but that's just fine because it's already implemented (in my superclass)". Alternatively, you can avoid @dynamic by supplying an overriding implementation: - (id<TKOutlineViewDelegate>) delegate { return [super delegate]; } but the @dynamic version is a bit more elegant. With either alternative, this approach lets you avoid the clutter of the additional local variables. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
