JSUpdateLookup

Don't be shy, tell your customers about your awesome new features!

• Easily check if your iOS App Store app has an update available.
• Uses the iTunes Store Web Service.
• Get info about latest version and most recent release notes.
• Check for first launch of a recently updated app (useful for iOS7's auto updates).

Here's how to use JSUpdateLookup:

1. Create a property for the lookup

@property (nonatomic, strong) JSUpdateLookup *updateLookup; 

2. Get your App ID from iTunes Connect

NSUInteger myAppID = 012345678;

3. Initialize a lookup with either a delegate or a block

self.updateLookup = [JSUpdateLookup updateLookupWithAppID:myAppID andDelegate:self];

or

self.updateLookup = [JSUpdateLookup updateLookupWithAppID:myAppID andCompletionHandler:^(JSUpdateInfo *updateInfo, NSError *error) {
	// Do stuff	
}];

4. If you're using a delegate, implement the JSUpdateLookupDelegate protocol

- (void)updateLookup:(JSUpdateLookup *)updateLookup didFailWithError:(NSError *)error
{
	// Handle error
}

- (void)updateLookup:(JSUpdateLookup *)updateLookup didFinishWithInfo:(JSUpdateInfo *)updateInfo
{
	// Do stuff
}

5. The JSUpdateInfo object passed to your delegate or completion handler will contain the update info you need

• Whether an app update is available
• The current version of the app
• The latest version available on the App Store
• Most recent release notes

Use this info to display an update prompt with the latest version & most recent release notes to the user.

Optionally: Schedule a periodic lookup each time the app becomes active

JSUpdateLookup provides an easy way to periodically check for updates, as soon as the app becomes active. Just use the following method:

[self.updateLookup scheduleLookupWithInterval:24 * 60 * 60];

The above usage will check for updates each day (provided that the app is used).

Hope that you'll enjoy using JSUpdateLookup!
