iOS 13 statusBar错误

iphone xr切换场景提示报错statusBar错误，Use the statusBarManager object on the window scene instead

解决方案

if (@available(iOS 13.0, *)) {

             // iOS 13  弃用keyWindow属性  从所有windowl数组中取
             UIView *statusBar = [[UIView alloc]initWithFrame:[UIApplication sharedApplication].keyWindow.windowScene.statusBarManager.statusBarFrame] ;
             statusBar.hidden = !show;

         }else{

           NSString *key = @"statusBar";
            UIApplication *object = [UIApplication sharedApplication];
            UIView *statusBar = [[UIView alloc]init];
            if ([object respondsToSelector:NSSelectorFromString(key)]){
                statusBar = [object valueForKey:key];
            }
            statusBar.hidden = !show;

         }
