The status bar issue for both iOS6 and iOS7
iPhone 3.5-inch iOS 6 - Offset by 20 pixels
iPhone 3.5-inch iOS 7 - Can't see bottom of screen
iPhone 4-inch iOS 6 - Offset by 20 pixels
Using AutoLayout to fix it
Step1 - Adjust the height of the table view
Step2 - Ctrl + drag Top Layout Guide to table view
Step3 - Selected Vertical Spacing
Step4 - Verical Spacing Constraint
Step5 - Same as above, ctrl + drag Bottom Layout Guide to table view
It's working....enjoy it~~
