  1. iPhone API已经提供了系统写邮件界面的接口,使用MFMailComposeViewController，用来显示界面.  
  2. 项目中需要添加MessageUi.framework。头文件加入MFMailComposeViewControllerDelegate。#import <MessageUI/MessageUI.h>  
  3. sendMailViewController.m文件的实现：  
  4. - (void)viewDidLoad  
  5. {  
  6.     UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect];  
  7.     button.frame = CGRectMake(0, 40, 320, 50);
