you have to add following delegate method of scrollview in your *.m file.

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{
}

Ok. Let me explain in deep.

  • open your yourViewCtr.h file.
  • Place following two statements in yourViewCtr.h ( here yourViewCtr is assumed your view controller )

IBOutlet UIScrollView *scrForImg;
IBOutlet UIImageView *imgForScr;

  • Save yourViewCtr.h file & open yourViewCtr.xib file.
  • Drag & drop UIScrollView in your view controller's view from Interface builder library
  • Now, drag & drop UIImageView in that scroll view from Interface Builder library
  • Now, Connect both of them to files owner of xib.
  • Don't forget to connect the scrollview's delegate to files owner
  • Now, Set Max zoom to 5 ( according to your need )
  • Save yourViewCtr.xib

-(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{
return imgForScr;
}

Hope, It works for you dear. Add comment if any doubts.

Look into ImageKit. In particular, IKImageView. Theoretically, you can put that into your scrollview. I've been playing with this recently...

Granted, I only work in OSX, not iPhone, so your experiences may vary... I'm not sure that IKImageView exists for iPhone, but ImageKit seems to...
