How to get the frame.width during the animation

I register my View with UISwipeGestureRecognizer to recognize a left or right swipe. And the response operation is:

[UIView beginAnimations:@"slide" context:nil];
[UIView setAnimationDuration:4];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

CGRect frame = self.sliderImageView.frame;
if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft )
{
    frame.size.width = 0;
    self.sliderImageView.frame = frame;
}
else if (recognizer.direction == UISwipeGestureRecognizerDirectionRight)
{
    frame.size.width = 199;
    self.sliderImageView.frame = frame;
}

[UIView commitAnimations];

If it's possible to get the self.sliderImageView.frame.width of the displaying View? Because what I try to do so during the animation using NSLog(@"%f", self.sliderImageView.frame.size.width) is either 0 or 199. So is there any methods to get the frame.width?

During an animation, you can access the current value of properties using the view's layer's presentation layer. Include the QuartzCore framework in your project, import the QuartzCore header, and use this:

self.sliderImageView.layer.presentationLayer.frame.size.width

Reference here.

You'll get like this :

NSLog(@"%f",self.sliderImageView.frame.size.width);
