OBShapedButton 1.2.0

  • By

OBShapedButton

OBShapedButton is a UIButton subclass optimized for non-rectangular button shapes. Instances of OBShapedButton respond to touches only in areas where the image that is assigned to the button for UIControlStateNormal is non-transparent.

How to Install

Installation via CocoaPods

If possible, you should install OBShapedButton via CocoaPods:

$ edit Podfile
platform :ios
pod 'OBShapedButton'

Manual Installation

If you cannot use CocoaPods for whatever reason, manually add OBShapedButton.h, OBShapedButton.m, UIImage+ColorAtPixel.h, and UIImage+ColorAtPixel.m to your Xcode project.

Usage

  • Design your UI in Interface Builder with UIButtons as usual. Set the Button type to Custom and provide transparent PNG images for the different control states as needed.
  • In the Identity Inspector in Interface Builder, set the Class of the button to OBShapedButton. That's it! Your button will now only respond to touches where the PNG image for the normal control state is non-transparent.
