Detect which activity will be selected in UIActivityViewController

Question

I plan to use UIActivityViewController to share text to twitter, etc. I need to share different text to twitter, email, etc. As a result, I need to change text dynamically based on user selection. May I know a way to do?

I know a way like this. But it is only after action is done and I can't change text. UIActivityViewController - is there a way to know which activity was selected?

your link is clearly shows the answer then what the problem u are faced. — Anbu.Karthik, Jul 21 '15 at 10:27
It is because it only show after user tap on activity. I need to change text depending on what user tap (facebook? twitter?) — Khant Thu Linn, Jul 22 '15 at 08:44

You can implement an UIActivityItemSource and its itemForActivityType: method to provide content to match the user's selection.

This is explained on NSHipster. For your convenience I copy/pasted the relevant Objective-C code and description:

One example of how this could be used is to customize a message, depending on whether it's to be shared on Facebook or Twitter.

if ([activityType isEqualToString:UIActivityTypePostToFacebook]) {
    return NSLocalizedString(@"Like this!",nil);
} else if ([activityType isEqualToString:UIActivityTypePostToTwitter]) {
    return NSLocalizedString(@"Retweet this!",nil);
} else {
    return nil;
}
