iOS7 - 是否可以更改状态栏颜色？ [英] iOS7 - Is it possible to change status bar color?

问题描述

有没有人知道如何更改状态栏文字颜色？我想要橙色。

我不是说常规的黑色或白色
UIStatusBarStyleLightContent 或 UIStatusBarStyleBlackOpaque ;管他呢。

解决方案

没有文档化的方式可将橙子。

免责声明：这是所有未记录的领土，它可能不会被批准，当你将其提交到应用商店。

在iOS 7中，您可以执行此操作：

  ///设置状态栏文本颜色。成功时返回YES。 
 ///目前，这只有
 ///在iOS 7中工作。它使用未记录，非正式的API。 
 BOOL setStatusBarColor（UIColor * color）
 {
 id statusBarWindow = [[UIApplication sharedApplication] valueForKey：@statusBarWindow]; 
 id statusBar = [statusBarWindow valueForKey：@statusBar]; 
 
 SEL setForegroundColor_sel = NSSelectorFromString（@setForegroundColor：）; 
 if（[statusBar respondingToSelector：setForegroundColor_sel]）{
 // iOS 7+ 
 [statusBar performSelector：setForegroundColor_sel withObject：color]; 
 return YES; 
} else {
 return NO;在iOS5和iOS6中，也可以是
} 
} 
  

我没有尝试，因为它是更多的工作。然而，我发现了一种感兴趣的方法（在iOS 5和iOS 6中可用）。类 UIStatusBarItemView 有一个名为 -textColorForStyle：的实例方法（它接受一个整数并返回一个对象）。你可以通过monkey-patch来返回任何你喜欢的颜色。我不知道它是否会工作，虽然。您可能需要枚举所有状态栏项目，并手动调用 -setNeedsDisplay ，以使颜色更改立即可见，但谁知道...

注意：我只是在我的github页面上发布代码。

Does anyone know how to change the status bar text color? I want it orange.

I'm not talking about the regular black or white color UIStatusBarStyleLightContent; or UIStatusBarStyleBlackOpaque; or whatever.

解决方案

There is no documented way to change the text color to orange. However, it is definitively possible, because I just tried it out and it worked.

Disclaimer: this is all undocumented territorry... it will probably not be approved when you submit it to the app store. however, you may be lucky...

In iOS 7 you can do this:

/// sets the status bar text color. returns YES on success.
/// currently, this only
/// works in iOS 7. It uses undocumented, inofficial APIs.
BOOL setStatusBarColor(UIColor *color)
{
    id statusBarWindow = [[UIApplication sharedApplication] valueForKey:@"statusBarWindow"];
    id statusBar = [statusBarWindow valueForKey:@"statusBar"];

    SEL setForegroundColor_sel = NSSelectorFromString(@"setForegroundColor:");
    if([statusBar respondsToSelector:setForegroundColor_sel]) {
        // iOS 7+
        [statusBar performSelector:setForegroundColor_sel withObject:color];
        return YES;
    } else {
        return NO;
    }
}

in iOS5 and iOS6 it may be possible too, but I haven't tried, because it is much more work. However I have found a method of interest (available in iOS 5 and iOS 6). Class UIStatusBarItemView has an instance method called -textColorForStyle: (which takes an integer and returns an object). You may be able to monkey-patch it to return any color you like. I don't know if it will work, though. You may need to enumerate through all status bar items and call -setNeedsDisplay manually on each, in order to have the color change be visible immediately, but who knows...

Note: I just published the code at my github page too.
