UIView+PartialRoundedCorner

Allows rounding of just two corners of a UIView, instead of four.

Demo

The demo/ folder contains a demo project showing UIView+PartialRoundedCorner in use. Open and run it.

Usage

This code can round the corners on views of any class. Just copy the files under src/ into your project, import "UIView+PartialRoundedCorner.h", then call the following on any view:

[yourView setCornerRadius:… direction:…];

Where corner radius is a float, and direction is one of the following:

• UIViewPartialRoundedCornerDirectionTop - rounds the top-left and top-right corners
• UIViewPartialRoundedCornerDirectionRight - rounds the top-right and bottom-right corners
• UIViewPartialRoundedCornerDirectionBottom - rounds the bottom-left and bottom-right corners
• UIViewPartialRoundedCornerDirectionLeft - rounds the top-left and bottom-left corners
• UIViewPartialRoundedCornerDirectionAll - rounds all four corners. Like view.layer.cornerRadius, but it can end up being more helpful masking

Compatibility

This class has been tested back to iOS 6.0.

Implementation

This class is implemented by creating a mask layer for the view, setting the corner radius on that, and offsetting it to the top, bottom, left, or right to get the appropriate effect.
