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.

Screenshots

  • The left picture forces the user to update the app.
  • The center picture gives the user the option to update the app.
  • The right picture gives the user the skip the current update.
  • This option is configurable in HarpyConstants.h.

Installation Instructions:

Note: Harpy utilizes ARC. Add the -fobjc-arc compiler flag in the build phases tab if your project doesn't use ARC.

  1. Copy the 'Harpy' folder into your Xcode project.

  2. Import Harpy.h into your AppDelegate or Pre-Compiler Header (.pch)

  3. Configure the static variables in HarpyConstants.h, and remove the #warning after customizing said variables.

  4. Choose the approriate alert display by modifying kHarpyAlertType (default: kAlertType_Option) in HarpyConstants.h.

  5. In your AppDelegate.m, add only one of the checkVersion methods.

    • NOTE: Call only one of the Harpy methods, as they all perform a check on your application's first launch. Using multiple methods will result in multiple UIAlertViews to pop.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    // Present Window before calling Harpy
    [self.window makeKeyAndVisible]
    
    // Perform check for new version of your app 
    [Harpy checkVersion] 
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{

    /*
     Perform daily check for new version of your app
     Useful if user returns to you app from background after extended period of time
     Place in applicationDidBecomeActive:
     
     Also, performs version check on first launch.
    */
    [Harpy checkVersionDaily];

    /*
     Perform weekly check for new version of your app
     Useful if user returns to you app from background after extended period of time
     Place in applicationDidBecomeActive:
     
     Also, performs version check on first launch.
     */
    [Harpy checkVersionWeekly];
    
}

And you're all set!
