I have a ScrollableView containing several ImageViews. I want the user to close the view by a pinch gesture. Since I can't find any appropriate event, I'm looking for a way to obtain the current scaling of an image in the imageViews, so that I can close the slide show, when the user zooms out.
It certainly would be better to react on the pinch gesture. Does anyone know a way to get it?
How are you scaling the images?
If you use the scaling feature of a ScrollView, you can check the zoomScale property to know if the current view is zoomed or not.
