iOS开发之发送短信

              @前面配置和邮件发送一样         

//  调用系统API发送短信
- (void)didClickSendMessageButtonAction{
    
    if ([MFMessageComposeViewController canSendText] == YES) {
        
        MFMessageComposeViewController *messageVC = [[MFMessageComposeViewController alloc] init];
        //  设置代理<MFMessageComposeViewControllerDelegate>
        messageVC.messageComposeDelegate = self;
        //  发送To Who
        messageVC.recipients = @[@"18757289870"];
        messageVC.body = @"hello world";
        [self presentViewController:messageVC animated:YES completion:nil];
        
    }else{
    
        NSLog(@"此设备不支持");
    }
}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{
    
    switch (result) {
        case MessageComposeResultCancelled:
            NSLog(@"取消发送");
            break;
        case MessageComposeResultFailed:
            NSLog(@"发送失败");
            break;
        case MessageComposeResultSent:
            NSLog(@"发送成功");
            break;
        default:
            break;
    }
    
    [self dismissViewControllerAnimated:YES completion:nil];

}

//  调用系统应用程序发送消息
- (void)didClickSendMessage2ButtonAction{
    
    NSURL *url = [NSURL URLWithString:@"sms:18656348970"];
    if ([[UIApplication sharedApplication] canOpenURL:url] == YES) {
        
        [[UIApplication sharedApplication] openURL:url];
        
    }else{
    
        NSLog(@"失败");
    }

}
