iOS - 发送电子邮件



  • 简述

    我们可以使用 iOS 设备的电子邮件应用程序发送电子邮件。
  • 涉及步骤

    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];
    }
    @end
