title: Integrate a method with button "touch up inside" action
body: <p>I have a running project and now it is nearly completed but now i have a method in app delegate class and i want that this method should be called on all of the buttons in the project. One simple way is that i should add call to method in each button listener code. 
  But is there a way that i can make it wired with Button action "Touch up inside"</p>
