bounds as they may change with rotation
Aspect ratio must be maintained
Check aspect ratios to see which dimension dominates
scaling.
Scale up or down to make critical dimension just fit
Make sure to set your scale factor for smooth changes.

Image Scaling – The Simple Way
 Let the storyboard do most of the work

Layout detail view controller




Top level view has UIToolbar and UIScrollView
UIScrollView has UIImageView
Set scroll view’s min and max zoom levels
Set UIImageView’s mode to “Aspect Fit”

Top level and scroll views set to “Scale to Fit” (default)
 Code in PhotoScrollViewController


Let setPhoto handle all image loading activity
In main queue portion of setPhoto add:


self.photoScrollView.contentSize=image.size;
self.photoScrollView.zoomScale = 1.0;
