将 UIWebview 的当前 URL 分享到 Facebook 和 Twitter

Question

所以我想使用 Xcode 中的社交框架将我的 webview 的当前 URL 分享到 facebook 和 twitter，谁能告诉我如何做到这一点，这是我的代码

- (IBAction)social:(id)sender {
    UIActionSheet *share = [[UIActionSheet alloc] initWithTitle:@"Pass on the news!" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:nil otherButtonTitles:@"Post to Twitter", @"Post to Facebook", nil];

    [share showInView:self.view];
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (actionSheet.tag == 0) {
        if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {
            SLComposeViewController *tweetSheet =[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
            [tweetSheet setInitialText:@"Check out this article I found using the 'Pass'  iPhone app: "];
            [self presentViewController:tweetSheet animated:YES completion:nil];
        } else {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Sorry" message:@"You can't send a tweet right now, make sure you have at least one Twitter account setup and your device is using iOS6 or above!." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [alertView show];
        }
    }
}
