app get crashed while navigating to RootViewController from Message popup

Question

I used MFMessageComposeViewController class for sending messages. My app get crashed in a particular situation. i e, When Message UI popup comes, user presses home button, app goes background and when come back, I wrote the code to navigate to the root view controller in applicationDidBecomeActive delegate. Please let me know if any suggestions?

Answer 1

In app delegate you are assigning the rootviewcontroller and in applicationDidBecomeActive you are redirecting into rootviewcontroller, why not to try directly assign the viewcontroller instead of rootviewcontroller.. You can at least try it, not sure it will work but still try once..

Answer 2

I had the same problem, and it was solved by removing the break points, as 120hit suggested.

But, since I needed the breakpoints to check the code, I found out that the reason was that my code tried to close a ViewController, so I put the "next code" inside the completion block:

 [presentingViewController dismissViewControllerAnimated:YES completion:^{
        self.currentMatch = match;

        GKTurnBasedParticipant *firstParticipant =
        [match.participants objectAtIndex:0];

        if (firstParticipant.lastTurnDate) {
            [delegate takeTurn:match];
        } else {
            [delegate enterNewGame:match];

        }
}];
