回答1:
Did you create the link between the button and the implementation? The implementing class should have an IBOutlet of type UIButton. Bind the IBOutlet to the button in Interface builder. This will cause the button to automatically be instantiated when the view is rendered and the BAD ACCESS should be alleviated.
回答2:
In my case it was a modal window which I released after opening. Thus any button which I clicked to try to call ANY IBAction would not work from that Modal View and kill the app with SIGBART or BAD_EXEC errors.
