iOS程序内发短信

1、程序外发短信

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@sms://10086]];

2、程序内发短信，发完短信自动返回应用

　　（1）首先导入框架MessageUI.framework

　　(2) 引入头文件 #import <MessageUI/MessageUI.h>

　　(3) 实现代理方法 <MFMessageComposeViewControllerDelegate, UINavigationControllerDelegate>

3、直接上代码

- (void)showMessageView{

    if ([MFMessageComposeViewController canSendText]) {

        MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

        controller.recipients = [NSArray arrayWithObject:@"10086"];

        controller.body = @"测试发短信";

        controller.messageComposeDelegate = self;

         [self presentViewController:controller animated:YES completion:nil];

        [[[[controller viewControllers] lastObject] navigationItem] setTitle:@"测试短信"];
    }else{

        [self alertWithTitle:@"提示信息" msg:@"设备没有短信功能"];
    }
}

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

    [controller dismissViewControllerAnimated:YES completion:nil];

    switch (result) {
        case MessageComposeResultCancelled:
            [self alertWithTitle:@"提示信息" msg:@"发送取消"];
            break;

        case MessageComposeResultFailed:
            [self alertWithTitle:@"提示信息" msg:@"发送失败"];
            break;

        case MessageComposeResultSent:
            [self alertWithTitle:@"提示信息" msg:@"发送成功"];
            break;

        default:
            break;
    }

}

- (void) alertWithTitle:(NSString *)title msg:(NSString *)msg {

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                    message:msg
                                                   delegate:self
                                          cancelButtonTitle:nil
                                          otherButtonTitles:@"确定", nil];

    [alert show];  

}
