I\'m following the second tip from here. In this tip two UIBarButtonItems are put together in a UIToolbar. Finally, the UIToolbar is added to the UINavigationBar. Now to my prob
There's no guarantee that UIToolbar draws seamlessly inside a UINavigationBar; this might be responsible for the white line you're seeing.
You might be able to subclass UIToolbar so that it doesn't draw (i.e. override -drawRect: to not do anything).
