仅当popToViewController时，iOS 8中的EXC_BAD_ACCESS

Question

Ive been working on this problem for the past week and I have not been able to solve it. I was able to find where specifically the exception was being thrown from the help of some stack overflow advice using Zombie process and found that when i do a popToViewController in iOS 8 for some reason iOS 8 looses something in my flow but i have no idea what it is. I think it may have to do with the navigationController and I've tried various ways to popToViewController .

My question is if anyone sees what the culprit might be in the below code ALSO is there a better way to pop to a view controller for iOS 8 users. The crash occurs when the user is back at View 2 and presses on any button in the view whether it be a UIButton that moves to another view or tries to move back using the navigationButton .

The flow is this: View 1 --> View 2 --> View 3 --> View 4 === View 4 pops back to View 2 :

VIEW 4: ChooseTempatureViewController :

Class classToPopTo = [BuildTempatureViewController class];
        for (UIViewController *view in [self.navigationController.viewControllers objectEnumerator]) {
            if([view class] == classToPopTo){
                NSLog(@"%s STARTED POP TO", __PRETTY_FUNCTION__);
                [self.navigationController popToViewController:view animated:YES];
                return;
            }
        }

View 2 : TempatureViewController :

Press any button and receive EXC_BAD_ACCESS and with zombie process enabled it gave me this as the Zombie

[TempatureViewController navigationController:animationControllerForOperation:fromViewController:toViewController:]: message sent to deallocated instance 0x86d67720

Any Advice to help my iOS 8 users would be greatly appreciated, project is using ARC Also I'm using XIBs

Have you tried any other solution, like using Unwind Segue. Here is an example: https://spin.atomicobject.com/2015/04/23/unwind-segue-set-destination/ . Hope this helps
