How big data can we transfer between iPhone applications

Question

I want to use "Custom URL Scheme" to transfer data from application to other application in iPhone. Can I ask: How big data can we transfer from app to app?

Thank you!

Answer 1

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.
