popViewController forces navigationbar title to align left

Question

I am experiencing a weird glitch where a normal titleview on a viewcontroller suddenly aligns left when popViewControllerAnimated: is called. Does anyone seem to be experiencing a similar issue?

Answer 1

I tried to pinpoint the issue and it occurs when I have this set:

[[UIBarButtonItem appearance] setBackgroundVerticalPositionAdjustment:1.0f forBarMetrics:UIBarMetricsDefault];

After removing this line, the titleview doesn't glitch or align left when popping the view controller. I would also like to note that I have a custom background image for the barbuttonitem. This is the first time I've ever experienced such an issue, hope it helps someone.
