How to disable double tap zoom behaviour? (iOS)



We have one problem in PDF editing. When we sign( with free hand tool) and do fast double tap it recognizes as zoom.
We want to disable zoom when we do sign/draw in the pdf. Due Could you please let us know how to achieve this?


The double tap behaviour is implemented in the Tool base class (method handleDoubleTap:). You could override the
method in the free hand tool to do nothing in response to this event.
