iOS – How to Drag and Scale an UIImageView over another UIImageView


We can drag and scale an UIImageView over another UIImageView using two gestures :

For Scaling an Image View : UIPinchGestureRecognizer

We've bought a Shopware Extension which is a hybrid App, which we can now offer in the Google Play Store and the IOS App Store. I'am still impressed how fast and how sharp the support team leads us through every process of the App-Store clarification. Very fast and useful response.
