Autostart
Allows you to animate without code. Don't need to use this is if you plan to start the animation in code.
Autohide
Saves you the hassle of adding a line "layer.alpha = 0" in viewDidLoad().
Known issue
Animations won't autostart when view is reached via performSegueWithIdentifier.
Animations using IBInspectables are currently not working in iOS 7. iOS 8 is supported. We're looking for a fix. Animations in code works for both iOS 7 and 8.
