Answer 1

With NSData , you can add image to UIActivityViewController . Try below one.

NSString *text = @"your text goes here";

NSData *Da = UIImageJPEGRepresentation([UIImage imageNamed:@"Icon.png"], 1.0);

NSArray * activityItems = @[text,Da];

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:[NSArray arrayWithObjects:nil]];
activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo]; //or whichever you don't need 
[activityVC setCompletionHandler:^(NSString *activityType, BOOL completed) {

}];
[self presentViewController:activityVC animated:YES completion:nil];
