iOS development Project-26 modifying system settings for Uitabbar

iOS development Project-26 modifying system settings for Uitabbar

A simple explanation

1. Realistic effects in two systems of IOS6 and iOS7

2. Results required (basically consistent in IOS6 and iOS7)

Ii. setting and structure of Uitabbar

1. Try adjusting the Uitabbar

UIButton: Inherit from Uicontrol

Print view the internal structure of each child control

2. Modifying System Properties

Note: Under the IOS6 system
