  步骤 1 - 创建一个简单的 View based application.

  步骤 2 - 选择您的项目文件，然后选择目标，然后添加 MessageUI.framework.

  步骤 3 - 添加一个按钮 ViewController.xib 并创建用于发送电子邮件的操作。

  步骤 4 − 更新 ViewController.h 如下 -

  
  #import <UIKit/UIKit.h>
  #import <MessageUI/MessageUI.h>
  @interface ViewController : UIViewController<MFMailComposeViewControllerDelegate> {
     MFMailComposeViewController *mailComposer;
  }
  -(IBAction)sendMail:(id)sender;
  @end
  

  步骤 5 − 更新 ViewController.m 如下 -

  
  #import "ViewController.h"
  @interface ViewController ()
  @end
  @implementation ViewController
  - (void)viewDidLoad {
     [super viewDidLoad];
  }
  - (void)didReceiveMemoryWarning {
     [super didReceiveMemoryWarning];
     // Dispose of any resources that can be recreated.
  }
  -(void)sendMail:(id)sender {
     mailComposer = [[MFMailComposeViewController alloc]init];
     mailComposer.mailComposeDelegate = self;
     [mailComposer setSubject:@"Test mail"];
     [mailComposer setMessageBody:@"Testing message 
     for the test mail" isHTML:NO];
     [self presentModalViewController:mailComposer animated:YES];
  }
  #pragma mark - mail compose delegate
  -(void)mailComposeController:(MFMailComposeViewController *)controller 
     didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
     
     if (result) {
        NSLog(@"Result : %d",result);
     }
     
     if (error) {
        NSLog(@"Error : %@",error);
     }
     
     [self dismissModalViewControllerAnimated:YES];
