objective c - Disabling scrolling when image is zoomed -

-

i have image inside uiscrollview. want happen if zoomed in particular position, want disable scrolling (both vertical , horizontal) remain on zoomed area. can give me ideas on how this?

two things keep in mind:

  1. make sure want when need disable scroll. (you can use methods uiscrollviewdelegate accomplish that).
  2. make contentsize of uiscrollview same size of frame. way both horizontal , vertical scroll disable.
cgrect myscrollviewrect = myscrollview.frame; cgsize myscrollviewframesize = cgsizemake(myscrollviewrect.frame.size.width, myscrollviewrect.frame.size.height); myscrollview.contentsize = myscrollviewframesize;

for clarity putted more code need to.
