在iOS 7中基于不同ViewControllers设置灯状态栏文本颜色的正确方法 [英] The correct way to set a light status bar text color in iOS 7 based on different ViewControllers
问题描述
我需要让嵌入在 UINavigationController
中的特定ViewController具有灯状态栏文本颜色(但其他 ViewController
s表现不同)。我知道至少有3种方法,但在我的情况下,这些方法都不起作用。
I need to let a specific ViewController embedded in an UINavigationController
to have light status bar text color (but other ViewController
s to behave differently). I am aware of at least 3 methods, none of which however work in my case.
-
如何在iOS 7中更改状态栏文本颜色,方法主要是:
- 在plist中将
UIViewControllerBasedStatusBarAppearance
设置为YES
- 在viewDidLoad中执行
[self setNeedsStatusBarAppearanceUpdate];
-
添加以下方法:
- Set the
UIViewControllerBasedStatusBarAppearance
toYES
in the plist - In viewDidLoad do a
[self setNeedsStatusBarAppearanceUpdate];
Add the following method:
- (UIStatusBarStyle)preferredStatusBarStyle{
return UIStatusBarStyleLightContent;
}
在iOS 7.0上运行.3,这个方法对我不起作用,因为即使我正确地实现了所有3个步骤,也永远不会调用 preferredStatusBarStyle
。
Running on iOS 7.0.3, this method does not work for me, since even after I have implemented all 3 steps correctly, preferredStatusBarStyle
is never called.
UIStatusBarStyle PreferredStatusBarStyle在iOS 7上不起作用,方法主要是:
设置 navigationBar
的 barStyle
到 UIBarStyleBlackTranslucent
会给出白色状态栏文本(即 UIStatusBarStyleLightContent
)和 UIBarStyleDefault
将提供黑色状态栏文本(即。 UIStatusBarStyleDefault
)。
Setting your navigationBar
’s barStyle
to UIBarStyleBlackTranslucent
will give white status bar text (ie. UIStatusBarStyleLightContent
), and UIBarStyleDefault
will give black status bar text (ie. UIStatusBarStyleDefault
).
这种方法在iPhone上公平公正,但不适用于iPad。
This method works fair and square on iPhone, but not on iPad.
设置 UIViewControllerBasedStatusBarAppearance
在plist中 NO
,并使用
Setting the UIViewControllerBasedStatusBarAppearance
to NO
in the plist, and use
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
这显然不适用于这种情况,因为我只需指定不同的状态栏颜色两个 ViewController
s。
This clearly doesn't apply in this case, since I need to only specify different status bar colors for two of the ViewController
s.

推荐答案
对于有 UINavigationController
出现此问题的人我可以推荐创建一个自定义 UINavigationController
并在其上实现 preferredStatusBarStyle
,如下所示:
For people having this problem with a UINavigationController
I can recommend creating a custom UINavigationController
and implementing the preferredStatusBarStyle
on it like this:
- (UIStatusBarStyle)preferredStatusBarStyle
{
return [self.topViewController preferredStatusBarStyle];
}
这样,状态栏样式将是顶视图控制器的样式。现在你可以实现视图控制器的 preferredStatusBarStyle
了。
That way the statusbar style will be that of the top view controller. Now you can implement the view controller's preferredStatusBarStyle
anyway you like.
