当点击电子邮件地址时设置默认主题

Question

我正在使用dataDetectorTypes属性与UITextView.code工作正常。

当我点击链接的电子邮件作曲家出现带有预填充：[电子邮件地址]，但我想设置默认主题：[主题字符串]也。

我该怎么做？

Answer 1

MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init]; 

    mailController.mailComposeDelegate = self; 

if([MFMailComposeViewController canSendMail]){ 
    [mailController setSubject:@"Subject"]; 
    [mailController setMessageBody:@"Email body here" isHTML:NO]; 
    [mailController setMessageBody:[self getInFo] isHTML:YES]; 
    [mailController setToRecipients:[NSArray arrayWithObject:@"xx@xxx.com"]]; 
    [mailController setTitle:@"Title"]; 

    [self presentModalViewController:mailController animated:YES]; 
}else{ 
    [mailController release]; 
}

1）拳头将<UITextViewDelegate, MFMailComposeViewControllerDelegate>添加到包含textview的类中。

您必须添加两个进口该类：

#import <MessageUI/MessageUI.h> 
#import <MessageUI/MFMailComposeViewController.h> 

2）添加一个变量：MFMailComposeViewController（在这个例子中mailVC，你也可以将其添加为您的.h类属性）

3）实施下一个方法：

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange 

这允许截取特定的url交互。您可以取消特定的相互作用，并添加自己的行动，例如：

-(BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange{ 
    //EXAMPLE CODE 
    if ([[URL scheme] isEqualToString:@"mailto"]) { 

     mailVC = [[MFMailComposeViewController alloc] init]; 
     [mailVC setToRecipients:@[@"your@destinationMail.com"]]; 
     [mailVC setSubject:@"A subject"]; 
     mailVC.mailComposeDelegate = self; 

     [self presentViewController:mailVC animated:YES completion:^{ 
      // [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; 
     }]; 
     return NO; 
    } 
    return YES; 
} 

3）要关闭MFMailComposeViewController变量：

-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{ 
    [mailVC dismissViewControllerAnimated:YES completion:nil]; 
} 

这对我的作品！
