IOS发送电子邮件

---

简介

我们可以使用IOS设备中的电子邮件应用程序发送电子邮件。

实例步骤

1、创建一个简单的View based application

2、选择项目文件，然后选择目标，然后添加MessageUI.framework

3、在ViewController.xib中添加一个按钮，创建用于发送电子邮件的操作（action）

4、更新ViewController.h,如下所示

#import <UIKit/UIKit.h>

#import <MessageUI/MessageUI.h>



@interface ViewController : UIViewController<MFMailComposeViewControllerDelegate>

{

    MFMailComposeViewController *mailComposer;

}



-(IBAction)sendMail:(id)sender;



@end

5、如下所示，更新ViewController.m

#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];



}



@end
