问题描述
我有一个具有 UINavigationBar 的应用程序，并且我已将色调颜色设置为黑色，如下所示:
I have an app which have a UINavigationBar and I have set the tint color to black like this:
self.navigationController.navigationBar.tintColor = [UIColor blackColor];`
我在 IOS 6 中测试过，它是黑色的.但是，当我在 iOS 7 中尝试相同的应用程序时，它显示为默认导航栏.
I have tested it in IOS 6 and it's black. However, it appears as the default navigation bar when I tried the same app in iOS 7.
正如标题所说，它不起作用吗?
As the title says, is it not working?
推荐答案
需要设置 barTintColor 属性.
You need to set the barTintColor property.
您可以使用 Tint (barTintColor) 字段为导航栏背景指定自定义色调颜色.默认背景色为白色.
You can specify a custom tint color for the navigation bar background using the Tint (barTintColor) field. The default background tint color is white.
