How to make the UINavigationBar background transparent?

advertisements

First of all, I've seen all the answers at How to make UINavigationBar Transparent in IOS 8? Transparent UINavigationBar and Make UINavigationBar transparent.

They just don't seem to work for me.

My regular view controller (before trying to make the navigation bar transparent) doesn't have any issues:

I'm using (tried both in viewDidLoad and viewWillAppear:):

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

I'm getting this:

Gray status bar background, completely white navigation bar which doesn't blend with the status bar, and then the view starts. All the 'solutions' at the other questions' answers' yield the same result for me.

I've also tried setting self.edgesForExtendedLayout = UIRectEdgeNone; or self.edgesForExtendedLayout = UIRectEdgeAll; but that also didn't have any impact.

How can I make my navigation bar transparent without messing up everything?

UPDATE: Following Warif Akhand Rishi's answer, I've changed self.navigationController.view.backgroundColor = [UIColor clearColor]; to self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];, now I'm getting a gray, unified status/navbar, but still not transparent:

UPDATE 2: I've hooked up the view debugger, and that gray background seems to come from deep down from the roots of view hierarchy, and my view's content is not extending up. I've tried self.edgesForExtendedLayout = UIRectEdgeAll; again with the latest code but still no avail:


Change your

self.navigationController.view.backgroundColor = [UIColor clearColor];

to this

self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
