UIActivityViewController customize text based on selected activity

Question

I want to customize text for the same information but when I am sharing it on Facebook I don't want to use the twitter hash tags or @username scheme...

How can I diversify text for sharing based on which sharing service would be used?

Ofcourse I'm using UIActivityViewController:

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:@[shareText, shareURL] applicationActivities:nil];

Answer 1

Instead of passing the text strings into the initWithActivityItems call, pass in your own sub-class of the UIActivityItemProvider class and when you implement the itemForActivityType method it will provide the sharing service as the 'activityType' parameter.

You can then return the customized content from this method.
