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.

Here's the [CustomTarBarController onButtonTouchDown:] method:
- (void)onButtonTouchDown:(NSUInteger)i {
self.selectedIndex =
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 severa 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.
why are you using a for statement? Comment it out and see if that works for you.
- (void)onButtonTouchDown:(NSUInteger)i {
self.selectedIndex =
[self.navigationController popToRootViewControllerAnimated:YES];
