    before adding the pan/pinch, did you finish the UI with proper scrollview and masked the circular view ? I beleieve adding those two is not difficult. Please provide code of what you tried. – Teja Nandamuri Oct 01 '15 at 18:34

    Try adding your gesture recognizers on the mask instead of the image view. Then scale or pan your image view relatively. – Ishan Handa Oct 01 '15 at 18:39
