What do you exactly want to display full screen? The image view or the scroll view that holds the image view?
Nothing should be changed other than the boundaries of the scroll view. And the code doesn’t depend on any constants related to the size of the scroll view, all scroll view related dimensions in the code are being freshly taken from the scroll view itself. You can just resize the scroll view in the IB and check whether it works fine or not. However if you want to change the size of the crop rectangle, then you’ll need to make some adjustments in the dragging and cropping code according to the new rectangle size. Hope this helps.

it was a very nice code. But there is one thing i want to ask

you set the size of image view to half CGRect imageViewFrame = CGRectMake(0.0f, 0.0f, roundf(w /2.0f), roundf(h / 2.0f)); in loadPhoto method.

and while croping there is
CGFloat cw = 300.0f / zoomScale;
CGFloat ch = 300.0f / zoomScale;

i can figure out how you calculated 300 number.

i want to show image on full screen i.e. 320 * 480 and so the size will be same as this. How will i achieve this.
thanks,
