setMessageBody 中忽略新行和返回

我是不是在做一些蠢事？我可以预填写并发送电子邮件，但“\r\n”在 emailBody 中被忽略：

- (void) sendEventInEmail
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;

    NSString *emailSubject = [eventDictionary objectForKey:EVENT_NAME_KEY];

    [picker setSubject:emailSubject];

    // Fill out the email body text
    NSString *iTunesLink = @"http://itunes.apple.com/gb/app/whats-on-reading/id347859140?mt=8"; // Link to iTune App link
    NSString *content = [eventDictionary objectForKey:@"Description"];
    NSString *emailBody = [NSString stringWithFormat:@"%@\r\nSent using <a href = '%@'>What's On Reading</a> for the iPhone.", content, iTunesLink];

    [picker setMessageBody:emailBody isHTML:YES];

    picker.navigationBar.barStyle = UIBarStyleBlack;

    [self presentModalViewController:picker animated:YES];
    [picker release];
}

如果 isHTML 设置 YES \n 不起作用，您必须设置 isHTML:NO 或使用 HTML 换行符，例如<br />输入一个new line.

<p> </p>插入一个新的段落这通常意味着双换行。

尝试使用 isHTML:YES:

[picker setMessageBody:@"1st line<br />2nd line<br />3rd line<br />and so on..." isHTML:YES]; 

如果 isHTML:NO 则输入 \n

[picker setMessageBody:@"1st line\n2nd line\n3rd line\nand so on..." isHTML:NO]; 

它会给你这个：

1st line
2nd line
3rd line
等等...
