UIcollectionview cell animation effect that moves the collection frame horizontally - ios

Question

I was wondering if someone can point me in the right direction. I have created a UIcollectionview that scrolls horizontally (one line). If a user scroll very fast, I would like the last cell to pull with it the collection frame showing what is behind the frame. What I do not want is for the last cell to move from its place and should the collection background. I added a pan gesture to the collection view, and with the logic I put in place, I see that the collection frame moves before the last cell is reached. same if you scroll backward to reach the first cell. I am new at this and there got to be a easy way to do it.
- (IBAction)handleGesture:(UIPanGestureRecognizer *)recognizer
{
CGPoint translation = [recognizer translationInView:self.view];
recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x/3,recognizer.view.center.y);
[recognizer setTranslation:CGPointMake(0, 0) inView:self.view];
if(recognizer.state == UIGestureRecognizerStateEnded)
{
[UIView animateWithDuration:0.6 delay:0 options:UIViewAnimationOptionAllowUserInteraction|UIViewAnimationOptionBeginFromCurrentState animations:^{
recognizer.view.center = CGPointMake(self.view.frame.size.width/2, recognizer.view.center.y);
} completion:nil];
[recognizer setTranslation:CGPointMake(0, 0) inView:self.view];
}
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
if ([gestureRecognizer isEqual:self.panGesture] && [otherGestureRecognizer isEqual:self.collectionview.panGestureRecognizer]){
return YES;
}
return NO;
}
- (BOOL) gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
if([gestureRecognizer isEqual:self.panGesture])
{
if(self.collectionview.contentOffset.x ==0)
{
return YES;
}
else if(self.collectionview.contentOffset.x >= (self.collectionview.contentSize.width - self.view.bounds.size.width))
{
return YES;
}
}
return NO;
