    Apple URL Scheme Usage: yourSchemeName://stringurl………

    Apple application need use - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url to handle url data. So I think your question may be equal to the maximum length of a URL.

    Safari (Browser)
    At least 80,000 characters will work. I stopped testing after 80,000 characters.
