Now that the GateGuru team has been developing on the iOS 5 SDK for awhile, I thought I'd pull together some lessons learned.

Declare your IBOutlet and IBActions within the private category within your implementation file. This makes them visible to interface builder without cluttering up the external interfaces and leaking implementation details.
Declare your IBOutlet properties as (nonatomic, weak). The weak reference implies a non-owning reference and ARC will nil it as necessary.
Delegate properties should be (nonatomic, weak) as well.
The designated initializer for UIView's is initWithFrame: when initialized programmatically. When loaded from a Storyboard or custom Nib, it is initWithCoder:
The designated initializer for UIViewController's is initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil when initialized programmatically. It is initWithCoder: when loaded from a Storyboard or Nib.

	// verifies receipt from iOS in-app purchase
	// returns:
	// 0 - if params missing
	// 1 - if receipt is valid
	// 2 - if invalid receipt, or invalid response from verification server
	// or bundle/in-app IDs are incorrect
