iphone - NSString 新行在邮件中不起作用？

Question

我有两个 UITextView，我想在用户发送邮件时显示它们。问题是我希望第二个 TextView 中的文本显示在邮件的新行中。

我尝试过使用 NSLog，它工作得很好，邮件 API 是否有问题或者为什么无法正常工作？

我的代码如下所示:

NSString *desc = descriptionTextView.text;
NSString *ingredients = ingredientsTextView.text;
NSString *emailBody = [NSString stringWithFormat:@"%@\n\n%@", desc, ingredients];
NSLog(@"%@\n\n%@", desc, ingredients);

-(void)displayComposerSheet 

{ MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self;

[picker setSubject:titleLabel.text];
NSString *desc = descriptionTextView.text;
NSString *ingredients = ingredientsTextView.text;
NSString *emailBody = [NSString stringWithFormat:@"%@\n\n%@", desc, ingredients];
NSLog(@"%@\n\n%@", desc, ingredients);
[picker setMessageBody:emailBody isHTML:YES];


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

}

- (void)viewDidLoad {
titleLabel.text = [recipeData valueForKey:@"title"];
descriptionTextView.text = [recipeData valueForKey:@"description"];
ingredientsTextView.text = [recipeData valueForKey:@"ingredients"];
[super viewDidLoad];

}

在撰写邮件时只需使用 html 标签即可正常工作。
使用html <br />标记新行。

NSString *desc = descriptionTextView.text;
NSString *ingredients = ingredientsTextView.text;
NSString *emailBody = [NSString stringWithFormat:@"%@ <br/> <br/> %@", desc, ingredients];
// [email setMessageBody:emailBody isHTML:YES]; 
NSLog(@"%@\n\n%@", desc, ingredients);
