When to 'release' in Cocoa management?

Hi, In some calls to Cocoa API subroutines we do: UIView *myView = [[UIView alloc] init]; [window addSubView:myView]; [myView release]; but sometimes you cannot release the temporarily allocated object, e.g. : UIDatePicler *picker; ... (picker was initialised somewhere) NSDate *date = [[NSDa

Yes. You release the object when one of three things occur: 1. You allocate the object yourself with the "alloc" message. 2. You allocate the object yourself with the shorthand "new" message. 3. You issue a retain message. So in both examples you gave you are required to release the object, as

Best Way to Simulate Keyboard
