I'm trying to make this transparency look in a ViewControllers Navigation bar:

WANTED:

Till now i got only this done. The bar is not losing its color:

Used code:

self.navigationController.navigationBar.barTintColor = [UIColor clearColor];
self.navigationController.navigationBar.translucent = YES;

Any idea how to fix this?

Answer 1

Try this:

[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
                         forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;

And in Swift

self.navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.translucent = true
