获取状态栏上的 view 数组

UIApplication *app = [UIApplication sharedApplication];    // 获取状态栏    UIView *statusView = [app valueForKey:@"statusBar"];    NSArray *subViews = [[statusView valueForKey:@"foregroundView"] subviews];复制代码

打印 subviews 就能看到状态栏上的图标数据

// 信号强度    "
    
     > [Item = 
     
       [UIStatusBarSignalStrengthItemView (Left)]]",    // 服务商    "
      
       > [Item = 
       
         [UIStatusBarServiceItemView (Left)]]",    // 网络状态码    "
        
         > [Item = 
         
           [UIStatusBarDataNetworkItemView (Left)]]", // 电池标志 "
          
           > [Item = 
           
             [UIStatusBarBatteryItemView (Right)]]", // 电池数字 "
            
             > [Item = 
             
               [UIStatusBarBatteryPercentItemView (Right)]]", // 闹钟 "
              
               > [Item = 
               
                 [UIStatusBarIndicatorItemView:Alarm (Right)]]", // 时间 "
                
                 > [Item = 
                 
                   [UIStatusBarTimeItemView (Center)]]"复制代码
                 
                
               
              
             
            
           
          
         
        
       
      
     
    

上面的是我的真机的打印结果,不同的状态栏可能结果不同，还有其他的显示的图标，如下：

// back to app     "UIStatusBarBreadcrumbItemView"    // 右上角的打开 Safari    "UIStatusBarOpenInSafariItemView"    // 定位标志    "UIStatusBarLocationItemView"复制代码

还有其余的图标，可能根据不同的需求来获取##
