Blur radius and UIView animation completion block

[romsi]

I use blur radius in UIView animation block (e.g your sample code "AnimatedBlurExample"). My problem is the completion block of [UIView animateWithDuration:completion:] is never called.

- (IBAction)toggleBlur
{
    if (self.blurView.blurRadius < 5)
    {
        [UIView animateWithDuration:0.5 animations:^{
            self.blurView.blurRadius = 40;
        } completion:^(BOOL finished) {
            NSLog(@"NEVER CALLED");
        }];
    }
    ...
}

This sample come from you sample code "AnimatedBlurExample".
