iOS7/8 translucent navigationBar top right corner of the black

Question

iOS8／iphone

When setting

navigationbar.translucent = yes;

If also set

blueVC.hidesBottomBarWhenPushed = yes;

push ViewController, navigationbar right corner displays a black.

Test Results：

Black areas are UIWindow by default. I changed the UIWindow background color to white and that fixed the issue. But this just looks better, does not completely resolved.

=======================

iOS7 strange animation when using hidesBottomBarWhenPushed

self.tabBarController.tabBar.hidden=YES;

This approach will lead to push the process tabbar disappear. It does not solve the problem.

Answer 1

Try this code:

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