UIBarButtonItem action

I've been having an issue in an app that I've developed under Xcode 4.5 DP4 where nothing happens when the user taps a Bar Button Item linked to an Action. I have tried several method for doing this such as linking the Bar Button Item inside a toolbar to an IBAction and also doing this programatically like this:

Code:

theButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonItemStyleBordered target: s:confused:elf action: @selector(theButtonPressed:)];

But none of these seem to work as nothing happens when the button is pressed. I never had this issue in previous versions of iOS. Does anyone have any idea what the problem is here? Thanks

 

The "" part just appeared when I copy pasted and posted the code. It was supposed to be there

 

Thanks for the info, but I just checked the code and it's fine. The strangest thing is that when I simply link the button to an IBAction from Interface Builder it actually works in the simulator but on my iPhone...
