I'm creating an app and i've browsed on the internet and i'm wondering how they make this transparent navigationBar like this:

UINavigationBar.appearance().translucent = true

but this just makes it look like following:

How can i make the navigationBar transparent like first image

解决方案

You can apply Navigation Bar Image like below for Translucent.

Objective-C:

[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
                     forBarMetrics:UIBarMetricsDefault]; //UIImageNamed:@"transparent.png"
self.navigationController.navigationBar.shadowImage = [UIImage new];////UIImageNamed:@"transparent.png"
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];

Swift 3:

self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.isTranslucent = true
self.navigationController?.view.backgroundColor = .clear

Hope it helps you..!
