What is annotation:(id)annotation in openURL method?

In the app delegate, there is this method

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

I am wondering what the "annotation" is? Also, how would I use it/view it to see what it contains?

Thanks

Solution

  • annotation: A property-list object supplied by the source application to communicate information to the receiving application.

    It is what the application that triggered the url opening wants to share with you.
