Question

I added the SwipeGesture to a View on my Page. If i make a Left Swipe the View switches to another Subview. Same if you do a right swipe.

The Problem is, that on one of my pages is a UISlider and if you change the value of this, the Swipe Gesture Triggers and Navigates to another Subview.

Is it possible to make a Swipe Gesture which triggers if you swipe with 2 Fingers?

Answer 1

Yes, you can use a swipe gesture with two fingers using the numberOfTouchesRequired property. I agree with @Jonathan.Peppers though that if you have conflicting gesture patterns it’s bad UX practice to slightly differentiate them by incrementing the touch points.

I would also recommend using this abstraction for using gestures and modify it using some sort of type check for swipe: https://gist.github.com/1453770

if(typeof(T) == typeof(UISwipeGestureRecognizer)) {
    ((UISwipeGestureRecognizer)fRecognizer).NumberOfTouchesRequired = 2;
}
