Thread 1: signal SIGABRT --builds successful but app crashes in simulator


Thread 1: signal SIGABRT --builds successful but app crashes in simulator



I got this error after putting in this section of code to an app I'm making


PageContentViewController *startingViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = @[startingViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];



Whenever I hit run, it says "Build Successful" but the app the crashes in the simulator. Can someone help me figure out what's wrong?





If it crashes, there is an error message in console? Could you give it?

FYI - a successful build does not mean your app doesn't have bugs that can lead to a crash at runtime.

You need to point out the exact line of code causing the crash and you need to update your question with the complete error message.

I can't find any reference to viewControllerAtIndex: in the developer docs. Is this a custom method you've written? If so, you need to provide it, because, if I had to guess, your app is crashing because you're trying to access an array index that doesn't actually exist.

viewControllerAtIndex:

The only thing may be wrong here is that [self viewControllerAtIndex:0]; returns NULL. You cannot create NSArray with NULL element.


[self viewControllerAtIndex:0];

What i'm trying to do is setting up an register and reset entity in order to deal with registrations and password reminders from an app. And then have the entity's passed to a custom controller to do some checks, balances and mails afterwards (haven’t gotten around to that yet).
