iOS how to make email address in a label clickable

Question

I believe this question has been asked and answered before, but I couldn't find it. I see an answer pointing to Fancy Label and Three20, but they are not quite what I want, or probably I missed some points.

Basically, I want get app users' feedback, so I will write in a big label, like

blah blah, email me at [email protected], and blah blah more.

I want the email address clickable, and open email composer so that users can edit and send.

That's all I need. How to get it? Thanks.

You could use UITextView as follows:

UITextView *myView = [[UITextView alloc] initWithFrame: CGRectMake(0, 0, 300, 50)];
    myView.text = @"this is http://google.com link";
    myView.editable = NO;
    myView.dataDetectorTypes = UIDataDetectorTypeLink;    
    //myView.message.dataDetectorTypes = UIDataDetectorTypePhoneNumber|UIDataDetectorTypeLink; for multiple data detection
    [self.view addSubview:myView];
    [myView release];

to select more than one data detection :

This is pretty simple,

create a label outlet in .h file

@interface ContactUsViewController : UIViewController<MFMailComposeViewControllerDelegate>

@property (strong, nonatomic) IBOutlet UILabel *mail1Lbl;

and place this code in.m file

- (void)viewDidLoad
{
    [super viewDidLoad];

    UITapGestureRecognizer* mail1LblGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(mail1LblTapped:)];
    // if labelView is not set userInteractionEnabled, you must do so
[mail1Lbl setText:@"[email protected]"];
    [mail1Lbl setUserInteractionEnabled:YES];
    [mail1Lbl addGestureRecognizer:mail1LblGesture];
}

- (void)mail1LblTapped:(id)sender
{
    if ([MFMailComposeViewController canSendMail])
    {

        MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
        mailer.mailComposeDelegate = self;
        [mailer setSubject:@""];
        NSArray *toRecipients = [NSArray arrayWithObjects:@"[email protected]", nil];
        [mailer setToRecipients:toRecipients];
        NSString *emailBody = @"";
        [mailer setMessageBody:emailBody isHTML:NO];
        mailer.navigationBar.barStyle = UIBarStyleBlackOpaque;
        [self presentModalViewController:mailer animated:YES];

    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Failure"
                                                        message:@"Your device doesn't support the composer sheet"
                                                       delegate:nil
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
        [alert show];
    }
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    switch (result)
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Mail cancelled: you cancelled the operation and no email message was queued.");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Mail saved: you saved the email message in the drafts folder.");
            break;
        case MFMailComposeResultSent:
            NSLog(@"Mail send: the email message is queued in the outbox. It is ready to send.");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Mail failed: the email message was not saved or queued, possibly due to an error.");
            break;
        default:
            NSLog(@"Mail not sent.");
            break;
    }
    // Remove the mail view
    [self dismissModalViewControllerAnimated:YES];
}

Webview using html / mailto: anchor should work just fine for this... may need to style it to the default iOS stuff but yeah.

Answer 4

You can use NSAttributedString for the same. Using this type of string will save a lot of time. But before using this you have to knowledge exact position of text. By knowing position and length you can customize that string easily. See this link for downloading sample project.NSAttributed string. But if you are using ios 6 then no need to use this sample code. You can use directly NSAttributedString. Because in ios6 UILabel supports this type of string.

lbl.aatributText = @"Your NSAttributed string".
