I try to kill some views with that code (and the same on the other way with the other view):
NSMutableArray *vcArray = [[NSMutableArray alloc] initWithArray: self.navigationController.viewControllers];
[vcArray removeObjectAtIndex: 0];
self.navigationController.viewControllers = vcArray;
[self performSegueWithIdentifier:@"segueOldView" sender:nil];
My problem, is that the memory is increasing, and I cannot manage it as it is with ARC.
