iphone - NSString 新行在邮件中不起作用？

Question

我有两个 UITextView，希望在用户发送邮件时显示。问题是我希望第二个文本视图中的文本显示在邮件的新行中。

我已经尝试过使用 NSLog，它在那里工作得很好，邮件 API 是否有问题或者为什么不能正常工作？

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];

}

在邮件撰写中，只需使用 html 标签，它就可以正常工作。
使用 html<br />标记换行。

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);
