I am inheriting QLPreviewController to set my own right button with my own handler.
It works fine on iOS 5.1, and I even managed to get it to keep the button after switching to Home and than back to my app.
[self.navigationItem setRightBarButtonItem:[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(openWithPressed:)]];
On iOS 4.3 the QuickLook appears with the standard buttons in the UINavigationItem (The right button is an "Open With" button, instead of my custom "Edit" button, with custom logic). Is there some known issue with setting the buttons in such a way? Should I do it in some other way?
