在格式字符串中添加回車符

Question

我試圖在我的電子郵件正文中的每個字符串之後得到回車符。我正在畫空白。

這是我使用的時刻代碼：

- (IBAction)mailButtonPressed { 
    MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init]; 
    controller.mailComposeDelegate = self; 
    [controller setSubject:@"Pressed Data..."]; 

    appDelegate= (TemplateIponeAppDelegate *)[UIApplication sharedApplication].delegate; 

    NSString *MessageBody=[NSString stringWithFormat:@" Hi: %@ F Result: %d , R Result: %d , B Result: %d, P Result: %d......... total Reults: %d total time :%@",clientName.text, appDelegate.FCount,appDelegate.RCount,appDelegate.BCount,appDelegate.PCount,appDelegate.TotalPressed,appDelegate.time]; 

    [controller setMessageBody:MessageBody isHTML:NO]; 
    [self presentModalViewController:controller animated:YES]; 
    [controller release]; 
}
