我相信这个问题之前已经被问过和回答过,但我找不到。我看到一个指向 Fancy Label 和 Three20 的答案,但它们并不是我想要的,或者我可能错过了一些要点。
基本上,我想得到应用用户的反馈,所以我会写一个大标签,比如
等等等等,给我发电子邮件 xxxxxx@gmail.com,等等等等。
我希望电子邮件地址可点击,并打开电子邮件编辑器,以便用户可以编辑和发送。
这就是我所需要的。如何得到它?谢谢。
您可以按如下方式使用 UITextView:
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];
选择多个数据检测:
这个很简单,
在 .h 文件中创建标签出口
@interface ContactUsViewController : UIViewController<MFMailComposeViewControllerDelegate>
@property (strong, nonatomic) IBOutlet UILabel *mail1Lbl;
并将此代码放在.m 文件中
- (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:@"xxxxxx@gmail.com"];
[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:@"xxxxxx@gmail.com", 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];
}
您可以使用NSAttributedString
相同的。使用这种类型的字符串将节省大量时间。但在使用它之前,您必须了解文本的确切位置。通过了解位置和长度,您可以轻松地自定义该字符串。请参阅此链接以下载示例项目。NSAttributed 字符串。但如果您使用的是 ios 6,则无需使用此示例代码。你可以直接使用 NSAttributedString。因为在 ios6 UILabel 支持这种类型的字符串。
lbl.aatributText = @"Your NSAttributed string".
编辑: 以下是您可以关注的一些链接: 1.在 UILabel 的 NSAttributedString 中创建可点击的“链接”? 2. Objective-C UILabel as HyperLink 3.如何让一个特定的词在文本中的意义可以触摸?
Webview using html / mailto: anchor 应该可以正常工作...可能需要将其样式设置为默认的 iOS 内容,但是是的。
