uinaviationcontroller pop animation become weird when status bar was hidden

Question

as picture : when the white controller in popping out with a interactive pop gesture , the red controller (which make the status bar hide) will show, and during the animation : the navigation bar seems to move up , and the controller's view is still in its position (not move up with navigation bar) ,so the view seems divided into two pieces in the pop out animation . how to fix it ?

Answer 1

In the first controller,add this code.

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [self.navigationController setNavigationBarHidden:YES animated:YES];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    [self.navigationController setNavigationBarHidden:NO animated:YES];
}
