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?

A:
Call removeTarget:action:forControlEvents: pass nil for the target, NULL for action, and use a control mask that sets all bits (UIControlEventAllEvents). Something like this:
[someControl removeTarget:nil
action:NULL
forControlEvents:UIControlEventAllEvents];

Thanks for the tip! Here's the full link I think (ie. to the section): "http://developer.apple.com/iphone/library/documentation/uikit/reference/UIControl_Class/Reference/Reference.html#//apple_ref/occ/instm/UIControl/removeTarget:action:forControlEvents:"

progrmr's suggestion works of course. To add to the answer here is a code snippet like the one I needed:[button removeTarget:nil action:NULL forControlEvents:UIControlEventTouchUpInside];

I tried about 10 times to edit this last night but SO kept giving me the fail whale ;-)

Aside: the -allTargets instance method returns an NSSet of all the instance's targets (nil if none).
