We encountered an issue where some users were unable to receive push during the overwrite installation process。 After a while it was normal again。 Checking the code shows that the registerForRemoteNotifications method is requested twice in a short period of time。 Therefore, we want to know what are the possible reasons for 410 unregistered。 Thanks。

I use this mehtod for screenshots，but it blocking mainthread, Is there another way to replace it ， { UIGraphicsBeginImageContextWithOptions(imageSize, NO, 0);   CGContextRef context = UIGraphicsGetCurrentContext();   for (UIWindow *window in [[UIApplication sharedApplication] windows]) {     CGContextSaveGState(context);     CGContextTranslateCTM(context, window.center.x, window.center.y);     CGContextConcatCTM(context, window.transform);     CGContextTranslateCTM(context, -window.bounds.size.width * window.layer.anchorPoint.x,                -window.bounds.size.height * window.layer.anchorPoint.y);     if ([window respondsToSelector:@selector(drawViewHierarchyInRect:afterScreenUpdates:)]) {       [window drawViewHierarchyInRect:window.bounds afterScreenUpdates:YES];     } else {       [window.layer renderInContext:context];     }     CGContextRestoreGState(context);   }   UIImage *image = UIGraphicsGetImageFromCurrentImageContext();   UIGraphicsEndImageContext(); } Is there an alternative way to take screenshots I need your help
