Objective-C 的

NSString *textToShare = @"StackOverflow Documentation!! Together, we can do for Documentation what we did for Q&A.";
NSURL *documentationURL = [NSURL URLWithString:@"http://stackoverflow.com/tour/documentation"];

NSArray *objectsToShare = @[textToShare, documentationURL];

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

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

let textToShare = "StackOverflow Documentation!! Together, we can do for Documentation what we did for Q&A."
let documentationURL = NSURL(string:"http://stackoverflow.com/tour/documentation")

let objToShare : [AnyObject] = [textToShare, documentationURL!]

let activityVC = UIActivityViewController(activityItems: objToShare, applicationActivities: nil)
self.presentViewController(activityVC, animated: true, completion: nil)
