I want to attach a three pinch zoom to my UITableView . When user uses three pinch zoom i want to show more details in uitableview where as in two pinch zoom i want normal zoom behavior . But when i am using UIPinchGesture it is only giving numberOfTouches as 2 even when i use three fingers .
Doc only speaks of 2 fingers
The user must press two fingers on a view while pinching it. When the user moves the two fingers toward each other, the conventional meaning is zoom out; when the user moves the two fingers away from each other, the conventional meaning is zoom in.
However, this post explains how to detect 3 fingers, using gestureRecognizer(_:shouldReceive:) https://stackoverflow.com/questions/51834037/avoid-three-finger-pinching-in-uipinchgesturerecognizer-in-swift
You could try to manage the 3 finger pinch in this func and return false after.
Hope that helps.
