Enable iPad target in sample project
Set deployment target for sample project to 7.0
Remove potential animation side effects

As discussed in #25, some views created by Apple animate when added to a subview, which could potentially interfere with the alert animations. By removing the addSubview: call from the CATransaction, the completion block for that transaction will always only be called after the animations relating to alerts have finished.
Use tintColor for button titles

Instead of hard-coding the system’s default tint color, SDCAlertViewContentView now uses self.tintColor for the button titles. That means that setting tintColor on an alert will affect the alert’s buttons as well as any alert subviews that use the tintColor.
