Delegates often own the things that delegate to them. There's nothing messy about this: NSSavePanel *savePanel = [NSSavePanel savePanel]; MySavePanelDelegate *delegate = [[MySavePanelDelegate alloc] init]; [savePanel setDelegate:delegate]; // savePanel doesn't retain delegate [delegate setSavePanel:savePanel]; // delegate retains savePanel [savePanel beginWithCompletionHandler:^(NSInteger result){ /* ... */ }]; But perhaps an even better idea would be to factor out more of the save-panel logic into that delegate object. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
