Block-based subclasses for UIActionSheet and UIAlertView, extracted from the commercial PSPDFKit PDF framework, because I love open source.
PSAlertView uses ARC and is tested with Xcode 4.5.2 (iOS 5.0+)
I'd love a thank you tweet if you find this useful.
Special thanks to Michał Zaborowski who wrote some of the drawing code used when tintColor is set on PSPDFAlertView.
