Remove 1px border under UINavigationBar - not working

Question

@IBOutlet var navBar: UINavigationBar!

self.navBar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
self.navBar.shadowImage = UIImage()

The code above works if the View Controller is embedded in a Navigation Controller and uses self.navigationController?.navigationBar.setBack... etc, but it doesn't work when using an IBOutlet (my example is not embedded in nav controller). The navigation bar is not translucent.

Any ideas?

Answer 1

Put this in you view controller (not in the uinavigationbar).

[[UINavigationBar appearance] setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setShadowImage:[UIImage new]];

Answer 2

Where exactly are you calling the appearance settings for a NavBar? When I try the following:

[self.myNC.navigationBar setShadowImage:[UIImage new]];
[self.myNC.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];

I have the desired effect.Could you provide us with a little more context perhaps?
