Horizontal scroll on UIScrollView without pan gesture

Question

How can I make it so that when I use my UIScrollView the pan gesture recognizer selector is not called.

I want to be able to scroll in the scroll view without the pan gesture selector being called.

Here is my pan detected function:

- (void)panDetected:(UIPanGestureRecognizer *)panRecognizer
{

    CGPoint translation = [panRecognizer translationInView:self.view];
    CGPoint imageViewPosition = self.draggableImage.center;
    imageViewPosition.x += translation.x;
    imageViewPosition.y += translation.y;

    self.draggableImage.center = imageViewPosition;
    [panRecognizer setTranslation:CGPointZero inView:self.view];
}

I do not want it to be called when I am using my UIScrollView at the bottom of the page.

So you want to add another gesture to the scroll view and disable the scroll view pan gesture sometimes but leave yours active? — Wain

He would probably have to write his own scrolling code, considering the pan gesture is the reason why the scroll view scrolls — A'sa Dickens

you could remove the gesture recognizer from the scroll view

NSArray* gestureRecognizers = [scrollView gestureRecognizers];
for (UIGestureReconizer* recog in gestureRecognizers) {
    if ( [recog isKindOfClass:[UIPanGestureRecognizer Class]] )
        [recog removeTarget:scrollView.delegate action:@selector(scrollViewDidScroll:)];
}

I don't understand why this is needed to be done, but here it is.
