ios – 如何在UITextView中单击电子邮件链接时打开iPhone的邮件应用程序？

正如 this answer中所指出的,您可以设置UITextView的dataDetectorTypes属性：

textview.editable = NO;
textview.dataDetectorTypes = UIDataDetectorTypeAll;

您还应该能够在Interface Builder中设置detectorTypes.

从Apple documentation开始：

单击UITextView中的电子邮件地址应该会自动打开Mail应用程序.

另外,如果您想从应用程序本身发送电子邮件,可以使用MFMailComposeViewController.

请注意,要@L_819_1@mFMailComposeViewController,需要在设备上安装Mail应用程序,并将一个帐户链接到该应用程序,否则您的应用程序将崩溃.

所以你可以用[MFMailComposeViewController canSendMail]来检查这个：

// check that a mail account is available
    if ([MFMailComposeViewController canSendMail]) {
        MFMailComposeViewController * emailController = [[MFMailComposeViewController alloc] init];
        emailController.mailComposeDelegate = self;

        [emailController setSubject:subject];
        [emailController setmessageBody:mailBody isHTML:YES];   
        [emailController setToRecipients:recipients];

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

        [emailController release];
    }
    // Show error if no mail account is active
    else {
        UIAlertView * alertView = [[UIAlertView alloc] initWithtitle:@"Warning" message:@"you must have a mail account in order to send an email" delegate:nil cancelButtontitle:NSLocalizedString(@"OK",@"OK") otherButtontitles:nil];
        [alertView show];
        [alertView release];
    }
