kristiandelay / demobutton

##DemoButton

An UIButton enhancement for:

• Programmatic generation of button images using Core Image filters
• Caching the generated images in a Nimbus in-memory cache
• Setting custom line spacing on button text using MTLabel

###Basic Usage

1. For generating filtered images -
   a) To use Nimbus memory caching (ref. https://github.com/jverkoey/nimbus), add NIMEMCACHE=1 to Preprocessor Macros, Project Build Settings
   b) Generate the filtered image using the UIButton category function
   - (UIImage *)generateImageUsingNormalImage:(UIImage *)normalImage cacheName:(NSString *)cacheName filterType:(NSString *)kFilterType filterAttributes:(NSDictionary *)attributes

2. For adjusting line spacing of button text -
   Use the button subclass DemoButton and set buttonLabel instead of titleLabel (ref. https://github.com/Tuszy/MTLabel)
