导航栏在弹出时变为黑色

问题描述

解决方案

当您弹出屏幕时您将返回上一屏幕。
在预览屏幕中，您必须在viewWillAppear中调用此方法。

   - （void）viewWillAppear：（BOOL）animated {
 [self.navigationController setNavigationBarHidden：YES animated：animated]; 
 [super viewWillAppear：animated]; 
} 
  

这对我有用。

The issue is when i pop my controller the navigation bar becomes black which is very irritating. Help required!

解决方案

When you Pop Your Screen You get back to Previous Screen.In Preview screen you have to call this method in viewWillAppear.

-(void) viewWillAppear: (BOOL)animated{
    [self.navigationController setNavigationBarHidden:YES animated:animated];
    [super viewWillAppear:animated];
}

This will work for me.
