Methods in Customized View did not get invoke in AppDelegate, Why?
- by NorthKyut
I want the methods pauseGame in customized UIView - MyGameView get invoked when the phone is locked or interrupted. So I have a pauseGame method but it can't stop the timer when user lock screen (command+L). The lock screen did appear but the game still running at the background. So I added the testPause method to MyGameView and MyGameAppDelegate and and put a breakpoint to debug it. When screen locked it, the screen lock appeared and the code did stop at the breakpoint. But when I tried to step into the testPause method, it didn't take me to the method in MyGameView (it just passed it, not skipped) and no message was printed on terminal by NSLog. Why? What did I miss?
