Harpy

Notify users that a new version of your app is available in the AppStore

About

Harpy is a utility that checks a user's currently installed version of your iOS application against the version that is currently available in the AppStore. If a new version is available, an instance of UIAlertView is presented to the user informing them of the newer version, and giving them the option to update the application.

The right picture gives the user the option to update the app.
This option is configurable in Harpy.h.

Installation Instructions:

Copy the 'Harpy' folder into your Xcode project. The following files will be added:
1. Harpy.h
2. Harpy.m
Import Harpy.h into your AppDelegate or Pre-Compiler Header (.pch)
Configure the 5 static variables in HarpyConstants.h
- You can remove the #warning in Harpy.h after customizing those variables.
In your AppDelegate.m, add [Harpy checkVersion] after calling makeKeyAndVisible:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
	// Customization on application launch
	
	…
	
	// Present Window
	[self.window makeKeyAndVisible]
	
	/*  
		Check AppStore for your application's current version. If newer version exists, prompt user.
		Declare immediatley after you call makeKeyAndVisible on your UIWindow iVar
	*/
	[Harpy checkVersion] 
}

And you're all set!
