iPhone 3.5-inch iOS 6 - Offset by 20 pixels
iPhone 3.5-inch iOS 7 - Can't see bottom of screen

Using AutoLayout to fix it

Step2 - Ctrl + drag Top Layout Guide to table view
Step3 - Selected Vertical Spacing

Step5 - Same as above, ctrl + drag Bottom Layout Guide to table view
It's working....enjoy it~~
