iOS开发之发送邮件

                     1.导入库文件:MessageUI.framework

                     2.引入头文件

                     3.实现代理<MFMailComposeViewControllerDelegate> 和 <UINavigationControllerDelegate>

@代码示例:

- (void)didClickSendEmailButtonAction{

    if ([MFMailComposeViewController canSendMail] == YES) {
        
        MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc] init];
        //  设置代理(与以往代理不同,不是"delegate",千万不能忘记呀,代理有3步)
        mailVC.mailComposeDelegate = self;
        //  收件人
        NSArray *sendToPerson = @[@"[email protected]"];
        [mailVC setToRecipients:sendToPerson];
        //  抄送
        NSArray *copyToPerson = @[@"[email protected]"];
        [mailVC setCcRecipients:copyToPerson];
        //  密送
        NSArray *secretToPerson = @[@"[email protected]"];
        [mailVC setBccRecipients:secretToPerson];
        //  主题
        [mailVC setSubject:@"hello world"];
        [self presentViewController:mailVC animated:YES completion:nil];
        [mailVC setMessageBody:@"魑魅魍魉,哈哈呵呵嘿嘿霍霍" isHTML:NO];
    }else{
    
        NSLog(@"此设备不支持邮件发送");
    
    }

}

- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{

    switch (result) {
        case MFMailComposeResultCancelled:
            NSLog(@"取消发送");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"发送失败");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"保存草稿文件");
            break;
        case MFMailComposeResultSent:
            NSLog(@"发送成功");
            break;
        default:
            break;
    }
    
    [self dismissViewControllerAnimated:YES completion:nil];
}

//  系统发送,模拟器不支持,要用真机测试
- (void)didClickSendSystemEmailButtonAction{

    NSURL *url = [NSURL URLWithString:@"[email protected]"];
    if ([[UIApplication sharedApplication] canOpenURL:url] == YES) {
        
        [[UIApplication sharedApplication] openURL:url];
    
    }else{
    
        NSLog(@"此设备不支持");
    }

}
