MFMessageComposeViewControllerDelegate   

主要在这里

- (void)showMessageView

{

    if( [MFMessageComposeViewControllercanSendText] ){

        MFMessageComposeViewController * controller = [[MFMessageComposeViewControlleralloc]init];//autorelease];

        //controller.recipients = [NSArray arrayWithObject:@"10010"];

        controller.body =@"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";

        controller.messageComposeDelegate =self;

        [selfpresentViewController:controller animated:YEScompletion:nil];

        [[[[controller viewControllers]lastObject] navigationItem]setTitle:@"XXXXXXXXXXX"];//修改短信界面标题

    }else{

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

    }

}

提示信息

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

{

    [controller dismissViewControllerAnimated:NOcompletion:nil];//关键的一句   不能为YES

   switch ( result ) {

        caseMessageComposeResultCancelled:

            [selfalertWithTitle:@"提示信息"msg:@"发送取消"];

           break;

        caseMessageComposeResultFailed:// send failed

            [selfalertWithTitle:@"提示信息"msg:@"发送成功"];

           break;

        caseMessageComposeResultSent:

            [selfalertWithTitle:@"提示信息"msg:@"发送失败"];

           break;

       default:

           break;

    }

}
