How to set a mail Subject in UIActivityViewController?

Question

I want to set subject for email sharing in UIActivityViewController and also want to share in Twitter. I know in Twitter if we want to share — we need compress

Answer 1

Check below code for the email for setting up your email subject:

UIActivityViewController* avc = [[UIActivityViewController alloc] initWithActivityItems:@[@"Your String to share"]
                                  applicationActivities:nil];
[avc setValue:@"Your email Subject" forKey:@"subject"];

avc.completionHandler = ^(NSString *activityType, BOOL completed) {
    // ...
};

Here the line

[avc setValue:@"Your email Subject" forKey:@"subject"];

Makes the subject as "Your email Subject" if user picks email option in the UIActivityViewController.

I hope it helps...
