NTDAppStoreRoundFramedButton is like the round framed button in iOS 7's App Store, more specifically, the button which says '$0.99' or 'DONE'.

How To Use it

1. Add NTDAppStoreRoundFramedButton into your project using CocoaPods or just draging the files into your project.
2. Drag out a UIButton from Storyboard.
3. Change it class to NTDAppStoreRoundFramedButton.

4. To make Autolayout work properly, set the Inset in Attribute Inspector to this:

   Top and bottom: 5,
   left and right: 11.

5. Then just use it as a UIButton.

6. For further customisation, have a look at NTDAppStoreRoundFramedButton.h, only 4 methods inside it.

How Does It Work

Basically it is setting following attributes to the specified value:

Attributes	Value
titleFontSize	13
cornerRadius	4
borderWidth	1
borderColor	button.tintColor.CGColor
topAndBottomInset	5
leftAndRightInset	11

And that's why you need to setup the inset in Attribute Inspector for Autolayout to work properly.
