It’s slightly better than that. Since ‘self’ is the observer, ‘selected(_:)’ is one of its own instance methods, so you don’t need to specify the class or ’self': > #selector (selected(_:)) If in addition the name of the method (selected) is unambiguous within the class of ‘self’, you don’t need to specify the parameters either: > #selector (selected) This doesn’t mean it doesn’t matter whether there’s a parameter or not, just that the Swift compiler can figure it out for you if you point it in the right direction. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
