The First show, It takes 8 seconds!

[IPOSDai]

CFAbsoluteTime startTime = CFAbsoluteTimeGetCurrent();

    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:container animated:YES];
    hud.mode = MBProgressHUDModeCustomView;
    hud.customView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"create_close"]];
    hud.detailsLabel.text = message;
    hud.detailsLabel.font = [UIFont systemFontOfSize:15];

    [hud hideAnimated:YES afterDelay:2.f];

    CFAbsoluteTime endTime = CFAbsoluteTimeGetCurrent();
    NSLog(@"执行时间： %f", endTime - startTime);

and the "Main Thread Checker" on. it is normal when the "Main Thread Checker" off.

me too. iOS 12.2 iphone max on-line debugging if only on device without debug, it's OK

run

• commonInit
  • setupViews
  • updateBezelMotionEffects
    • [bezelView addMotionEffect:group]; here , show error : Main Thread Checker: UI API called on a background thread: -[UIApplication applicationState] PID: 2405, TID: 598069, Thread name: com.apple.CoreMotion.MotionThread, Queue name: com.apple.root.default-qos.overcommit, QoS: 0

but [NSThread currentThread] show it's on main thread.

I have also appeared this problem, can I only turn off the "Main Thread Checker"?

meet this problem,too, but strange: on my iPhoneX 12.3.1 it works well on my iPhoneXR 12.2, it just stuck for seconds and reports the Main Thread Checker

[ruixingchen]

@helisHuZ problem fixed after I turned it off
