UIWindow doesn't updating subviews after addSubview - ios

Question

I'm adding a UIView as subview to current keyWindow and it shows fine.
Then when I update the subviews (UILabel, UIButton, UIImageView etc...) it doesn't get update.
I tried adding setNeedDisplay everywhere so it can update it but still no luck.
Adding to UIWindow:
trapAlarmActivity = [[TrapAlarm alloc] initWithUserInfo:params];
[trapAlarmActivity setNeedsDisplay];
[trapAlarmActivity.screenView setNeedsDisplay];
[[UIApplication sharedApplication].keyWindow addSubview:trapAlarmActivity];
[[UIApplication sharedApplication].keyWindow setNeedsDisplay];
Updating the UIWindow:
- (void)changeMessageBoxWithDistance:(NSInteger)distanceToTrap
{
distanceToTrap += arc4random()%100;
distance = distanceToTrap;
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(#"************changeMessageBoxWithDistance: %i", distanceToTrap);
trapType = globalTrap.getTrapType;
if ([ref integerForKey:kUpdate_Distance] == kACTIVE && trapType != CAMERA_LASER)
{
self.labelDistance.text = [NSString stringWithFormat:#"%i %#", distance, NSLocalizedString(#"meters", nil)];
self.labelDescription.text = globalTrap.getTrapDesc;
self.labelTrapType.text = GetTrapTypeString(trapType);
}
else
{
self.labelDistance.text = globalTrap.getTrapDesc;
self.labelDescription.text = GetTrapTypeString(trapType);
self.labelTrapType.text = #"";
}
[self setNeedsDisplay];
[[UIApplication sharedApplication].keyWindow setNeedsDisplay];
[[UIApplication sharedApplication].windows.firstObject setNeedsDisplay];
/*NSEnumerator *frontToBackWindows = [UIApplication sharedApplication].windows.reverseObjectEnumerator;
for (UIWindow *window in frontToBackWindows) {
[window setNeedsDisplay];
}*/
});
}
UPDATE-1:
Updated code to work on main thread, still no luck.
Only 1st UIView added as a subview shown.
UPDATE-2:
recursiveDescription when the UIView is presented on top of the keyWindow:

UPDATE-3:
I ended up turning the UIView to UIViewController and showing it via:
appDelegate.window.rootViewController = testViewController;
[appDelegate.window makeKeyAndVisible];
And dismissing it via pushing back the original viewController.

call setNeedsDisplay method on your application’s main thread when you want to adjust the layout of a view’s subviews.
