So apparently in some cases when that button is pressed and it's trying to switch to the root view controller, something goes wrong in the [NSMutableArray removeObjectsInRange:] call. I can't figure out what could be the problem there, does anyone have experience with this? Since it's a crash report from a user, I can't see which exception was thrown.

Edit: here's the full report I got.

Edit 2:

Here's the [CustomTarBarController onButtonTouchDown:] method:

- (void)onButtonTouchDown:(NSUInteger)i {
  self.selectedIndex = i;
  for (UINavigationController *_controller in self.viewControllers) {
    [_controller popToRootViewControllerAnimated:YES];
  }
}

Try using popToRootViewControllerAnimated: without animation. I remember that once I've got crashes that have been caused by several animations at once; for example, with code like this:

[self.modalView dismissModalViewControllerAnimated:YES];
[self.navigationController popToTootViewControllerAnimated:YES];

In my case I just set YES in second line to NO, and it helped.

Alexander N.

why are you using a for statement? Comment it out and see if that works for you.

- (void)onButtonTouchDown:(NSUInteger)i {
    self.selectedIndex = i;
    [self.navigationController popToRootViewControllerAnimated:YES];
}
