Does not work

This method is not ARC compatible. If you are using ARC you can simply replace the navigation bar using:
[navigationController setValue:navigationBar forKey:@"navigationBar"].

Hi Nitewriter:

I test your code on ios5.1, the custom navigation bar appears, but the back button on the bar doesn't work, it doesn't call popViewControllerAnimated method when tap back button, however the back button will disappear...it is weird.

best regards

iOS 5.x introduced changes to the UINavigationBar that cause issues when using this method of replacement. You should use the setValue:forKey: replacement I mentioned to ihmunro.

thanks for your feedback
