獲取狀態列上的 view 陣列
UIApplication *app = [UIApplication sharedApplication];
// 獲取狀態列
UIView *statusView = [app valueForKey:@"statusBar"];
NSArray *subViews = [[statusView valueForKey:@"foregroundView"] subviews];
複製程式碼列印 subviews 就能看到狀態列上的圖示資料

複製程式碼上面的是我的真機的列印結果,不同的狀態列可能結果不同，還有其他的顯示的圖示，如下：
// back to app
"UIStatusBarBreadcrumbItemView"
// 右上角的開啟 Safari
"UIStatusBarOpenInSafariItemView"
// 定位標誌
"UIStatusBarLocationItemView"
