iOS - Resize multiple views with touch-drag separators

Question

How can I resize views with a separator? What I\'m trying to do is something like Instagram layout app. I want to be able to resize views by dragging the line that separates

Answer 1

As per my best knowledge we can do this using UIGestureRecognizer and auto layout.

1. Use UIView as line separator.
2. Add Pan gestureRecognizer to separator line view.
3. Handle view movement in delegate protocol methods using UIView.animatewithDuration()
PanGestureRecognizer

Most important, don't forget to set/Check UserInteration Enabled for all line separator view in Attribute Inspector.
