iOS 7 Custom UINavigationBar TitleView moves when Pushing or Popping new View Controller

I am using a custom title view for a UINavigationBar with the following code:

// Set a label to the nav bar
THLabel *titleLabel = [[THLabel alloc] init];
titleLabel.text = @"Test";
titleLabel.font = [UIFont fontWithName:APP_FONT size:22.0];
titleLabel.frame = CGRectMake(0, 0, 100, 30);
titleLabel.textAlignment = NSTextAlignmentCenter;
titleLabel.textColor = CUSTOM_LIGHT_BLUE;
titleLabel.strokeColor = kStrokeColor;
titleLabel.strokeSize = kStrokeSize;
self.navigationItem.titleView = titleLabel;

The problem is that when presenting a new viewcontroller and then returning to the original view controller this custom view shifts and then re-centers itself. Please see the video for a demonstration of that.

Please see the video here:

I have disabled autoresizing of every subview for the navigation controller with both the storyboard and in code for each view controller:

// Set the navigation bar hidded on the log in view
UINavigationController* mainViewController = (UINavigationController*)self.appDelegate.window.rootViewController;
[mainViewController setNavigationBarHidden:YES];
[[mainViewController navigationBar] setAutoresizesSubviews:NO];

However it still resizes! How can I stop this - what am I doing wrong? Thanks!

It's reproducible for me only if I place setting titleView code in viewWillAppear. Moving it to viewDidLoad fixes the issue
