删除使用故事板创建的导航栏中的半透明栏

问题描述

我从故事板创建了一个navigationController，现在我正在尝试删除它的半透明选项

I created a navigationController from the storyboard and now i'm trying to remove it's translucent option

我把它放在我的appdelegate.m上

I've put this on my appdelegate.m

[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:52.0/255 green:152.0/255 blue:219.0/255 alpha:1]];
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

[[UINavigationBar appearance] setTranslucent:NO];

但这会导致我的应用程序出现无意义错误，所以我不确定这是不是正确的方法。

But this is crashing my app with a nonsense error, so I'm not sure if this is the right approach.

我发现了类似的问题，但没有解决我的问题：

I have found this similar question but didn't solved my problem:Navigation Controller Transparent Bar Style is not working

但是我我不知道该怎么做因为我没有变量navController，因为我从故事板创建了我的navigationController。如何以编程方式调用故事板导航控制器并执行类似的操作？

But I'm not sure how to do that because I don't have a variable navController since I created my navigationController from the storyboard. How can I call the storyboard navigation controller programmatically and do something like that?

谢谢

推荐答案

在导航堆栈上出现的第一个视图控制器上将其添加到 viewDidLoad ：

Add this to viewDidLoad on the first view controller appearing on the navigation stack:

self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
