Don't know your code but try playing around with the above code to see if you can filter your touches to the objects you want.

then use below code:

For that just define one function in collectionViewCell

<pre><code> @IBOutlet weak var mainScrollView:UIScrollView!
 func setup(){
 mainScrollView.minimumZoomScale=1
 mainScrollView.maximumZoomScale=10.0

 mainScrollView.delegate=self

 }

 func viewForZooming(in scrollView: UIScrollView) -&gt; UIView? {
 return yourimageviewinside of scrollview
 }

call this fuction in 
<code>collectionview(_,cellForItem )</code> method of collectionview

I'm trying to add a <code>UIScrollView</code> inside of a <code>UICollectionViewCell</code>. The idea is that you can use pinch to zoom the <code>UIScrollView</code> (and with it, the image within), but the scrollview doesn't seem to handle any gesture. I'm guessing they are being caught by the <code>UICollectionView</code>.

I've set the delegate of the <code>UIScrollView</code> to be the <code>UICollectionViewCell</code>, but none of the delegate methods are being called.

EDIT:
I've made a github repo with the code (simplified as much as I could). Even though it's just a few lines of code, I cannot see what I did wrong.

EDIT2: After the answer was found, I added the fixes to the above-mentioned repo, hope others find it helpful too :)

How to zoom a UIScrollView inside of a UICollectionViewCell?

我正在尝试在UICollectionViewCell中添加一个UIScrollView。这个想法是，您可以使用pinch来缩放UIScrollView (以及其中的图像)，但scrollview似乎不能处理任何手势。我猜他们被UICollectionView抓到了。我已将UIScrollView的委托设置为UIColl...
