I have added multiple target-action-forControlEvents: to a UIButton. I'd like to remove all of these in one go without deallocating anything. I will then set new targets.

Is this possible and how do I go about it?

Call removeTarget:action:forControlEvents:, pass nil for the target, NULL for action, and use a control mask that sets all bits (UIControlEventAllEvents).

Objective-C

[someControl removeTarget:nil 
                   action:NULL 
         forControlEvents:UIControlEventAllEvents];

Swift 2

button.removeTarget(nil, action: nil, forControlEvents: .AllEvents)

Swift 3 or higher

button.removeTarget(nil, action: nil, for: .allEvents)
