以编程方式更改iOS7状态栏颜色，中期运行？

问题描述

限时删除！！

我正在尝试在运行中更改状态栏颜色，即在加载控制器时没有。我更改了视图的背景颜色，因此我需要将其从黑色更改为白色，反之亦然。

I’m trying to change the Status Bar colour mid-run, i.e. not when a controller is loaded. I change the view’s background colour, so I need to change it from the black to white and vice versa.

我知道我可以使用 preferredStatusBarStyle 和plist中的设置，但据我所知，它只会在首次启动视图控制器时设置它。我想改变它，例如，当我按下按钮时。

I know that I can change it using preferredStatusBarStyle and the setting in the plist, but as far as I can see that’ll only set it on first launching the view controller. I’d like to change it, for instance, when I hit a button.

我可以这样做吗？

推荐答案

• 转到您的应用程序Plist并将其添加为新行&将其设置为NO。

  • Go to your application Plist and add this as new row & set it as NO.

    View controller-based status bar appearance  NO
    

  
  

  添加bool以确定 UIStatusBar 颜色的状态&安培;添加一个Toggle方法

  Add a bool to determine state of UIStatusBar colour & add a Toggle method

  @property(nonatomic) BOOL black;
  
  
  -(void)toggleStatuSBar:(id)sender{
  
      if(black) {
          [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
          black = NO;
  
      }else {
          [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];
          black = YES;
      }
  }
  

  这里是一个样本ScreenShot

  here is a Sample ScreenShot
