Invisible box when implementing zoom on UIScrollView (iPad)
Firstly, I only have the graph view that display some nodes (a drag-able
image).
Then, I want this graph to be able to zoom in/out. In order to do so, I
added the UIScrollView (Black box in the picture below) and add the graph
view as a subview (Red box in the picture below).
The zoom functionality is working fine, but the thing is that there seems
to be an invisible box (Red box in the 2nd picture below) that not allow
my node to be dragged over this boundary.
Is there anyway to get rid of this invisible boundary ?
