程序内调用系统发短信
<pre>

import <messageui messageui.h=""></messageui>

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;
}

}
</pre>
发送短信
<pre>
-(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。

调用发短信的方法
<pre>
[self showMessageView:[NSArray arrayWithObjects:@13888888888,@13999999999, nil] title:@test body:@你是土豪么，么么哒];
