今天工作遇到要发短信（ios）的功能，于是随手记录了一下

ios中发送短信有两种

1.程序外调用系统短信

2.程序内调用系统发短信

第一种比较简单，直接调用url就可以了

oc下的代码为

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"sms:%@",@""]]]

oc版

swift下的代码

UIApplication.sharedApplication().openURL(NSURL(string: "sms:13888888888")!)

第二种

oc下的代码

1）导入MessageUI.framework，并引入头文件：

#import 

2）实现代理方法MFMessageComposeViewControllerDelegate

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    [self dismissViewControllerAnimated:YES completion:nil];
    switch (result) {
        case MessageComposeResultSent:
            //信息传送成功

            break;
        case MessageComposeResultFailed:
            //信息传送失败

            break;
        case MessageComposeResultCancelled:
            //信息被用户取消传送

            break;
        default:
            break;
    }
}

3）发送短信

-(void)showMessageView:(NSArray *)phones title:(NSString *)title body:(NSString *)body
{
    if( [MFMessageComposeViewController canSendText] )
    {
        MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init];
        controller.recipients = phones;
        controller.navigationBar.tintColor = [UIColor redColor];
        controller.body = body;
        controller.messageComposeDelegate = self;
        [self presentViewController:controller animated:YES completion:nil];
        [[[[controller viewControllers] lastObject] navigationItem] setTitle:title];//修改短信界面标题
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@提示信息
                                                        message:@该设备不支持短信功能
                                                       delegate:nil
                                              cancelButtonTitle:@确定
                                              otherButtonTitles:nil, nil];
        [alert show];
    }
}

参数phones：发短信的手机号码的数组，数组中是一个即单发,多个即群发。

4）调用发短信的方法

[self showMessageView:[NSArray arrayWithObjects:@,@, nil] title:@test body:@你是土豪么，么么哒];

Swift版本

import MessageUI

之后让vc继承MFMessageCompose的代理：

class CaipinDetailViewController: UIViewController,MFMessageComposeViewControllerDelegate
func canSendText() -> Bool{
    return MFMessageComposeViewController.canSendText()
    }//用来指示一条消息能否从用户处发送
    func configuredMessageComposeViewController() -> MFMessageComposeViewController{
    let messageComposeVC = MFMessageComposeViewController()
        messageComposeVC.messageComposeDelegate = self
        messageComposeVC.body = "HI! \(caipinArray[0].rest) 的 \(caipinArray[0].name) 味道很不错，邀你共享 -来自SoFun的邀请"
        return messageComposeVC

    }
     func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
        controller.dismissViewControllerAnimated(true, completion: nil)
    }

然后在按钮的action方法中加入以下代码：

@IBAction func share(sender: UIButton) {
        let shareView = ShareViewController()
        self.presentViewController(shareView, animated: true, completion: nil)
    }
    @IBAction func message(sender: UIButton) {
        if self.canSendText(){
        let messageVC = self.configuredMessageComposeViewController()
          presentViewController(messageVC, animated: true, completion: nil)
        } else {
        let errorAlert = UIAlertView(title: "不能发送", message: "你的设备没有短信功能", delegate: self, cancelButtonTitle: "取消")
        }

    }

我们在真机上测试一下，效果图：
