Restore navigationBar background image after setting it to [UIImage new]

Question

I needed a completely transparent navigation bar for the mapView so I did this:

[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarM         


        

Answer 1

Set nil for image of navigation Controller on viewWillDisappear on map view

Set this two method in your mapview

MapView.m

-(void)viewWillAppear:(BOOL)animated{
    [self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
    [self.navigationController.navigationBar setShadowImage:[UIImage new]];
}

-(void)viewWillDisappear:(BOOL)animated{
    [self.navigationController.navigationBar setBackgroundImage:nil forBarMetrics:UIBarMetricsDefault];
    [self.navigationController.navigationBar setShadowImage:nil];
}
