Navigation Bar subview tree might get corrupted issue

[iphonegamedeveloper]

My application is having UINavigationcontroller. I am performing some actions in viewWillAppear method.If the action is not successful then i am doing popover action(before viewDidAppear method gets called). In this scenario my app is getting crashed due to

"nested pop animation can result in corrupted navigation bar"
"Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted."


Could anybody help me to fix this issue?

When i moved my action to viewdDidAppear, it works fine. I hope doing popToRootViewController in viewDidLoad and viewWillAppear is dangerous.
