UIScrollView with 3 images

/ Published in: Objective C

Tips
1. This example is to make a horizontal image slider with 3 images for iPad.
2. To fix the orientation to horizontal only, modify project-Info.plist -supported interface orientations
3. The scrollView is added to view in code, there is no need to visually create a scrollView in the UIBuilder interface.
