【MessageUI】iOS调用 短信 与 邮件

虽然发短信和发邮件都可以使用 openURL去处理，但使用MessageUI可以做到回调成功失败，而且也非常简单；

发邮件

- (void)viewDidLoad {
    [super viewDidLoad];
    
    if ([MFMailComposeViewController canSendMail]) {
        MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
        controller.mailComposeDelegate = self;
       
        [controller setSubject:@"主题"];
        [controller setToRecipients:@[@"[email protected]"]];
        [controller setCcRecipients:@[@"[email protected]"]];
        [controller setBccRecipients:@[@"[email protected]"]];
        [controller setMessageBody:@"啥" isHTML:NO];
        
        NSString *path = [[NSBundle mainBundle] pathForResource:@"bg1" ofType:@"png"];
        [controller addAttachmentData:[NSData dataWithContentsOfFile:path] mimeType:@"png" fileName:@"附件"];
        
        [self presentViewController:controller animated:YES completion:nil];
    }
}

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

    switch (result) {
        case MFMailComposeResultCancelled:
            NSLog(@"取消");
            break;

        case MFMailComposeResultSaved:
            NSLog(@"已保存");
            break;
            
        case MFMailComposeResultSent:
            NSLog(@"已发送");
            break;
            
        case MFMailComposeResultFailed:
            NSLog(@"发送失败");
            break;
            
        default:
            break;
    }
}

发短信

- (void)viewDidLoad {
    [super viewDidLoad];
    
    if ([MFMessageComposeViewController canSendText]) {
        MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
        controller.messageComposeDelegate = self;
        
        controller.recipients = @[@"187********"];
        controller.body = @"晚饭吃了吗？";
        
        [self presentViewController:controller animated:YES completion:nil];
    }
}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {

    switch (result) {
        case MessageComposeResultCancelled:
            NSLog(@"取消");
            break;
            
        case MessageComposeResultSent:
            NSLog(@"已发送");
            break;
            
        case MessageComposeResultFailed:
            NSLog(@"发送失败");
            break;
            
        default:
            break;
    }
}
