IOS开发-发送短信

/*调用SendMessage界面*/
- (void)sendMsg:(NSString *)msg
{
    //首先判断当前设备是否可以发送短信
    if([MFMessageComposeViewController canSendText])
    {
        self.mc=[[MFMessageComposeViewController alloc] init];
        
        //设置委托
        self.mc.messageComposeDelegate=self;
        
        //短信内容
        self.mc.body=[[NSString alloc] initWithUTF8String:[msg UTF8String] ];
        
        //设置短信收件方
        [self presentViewController:self.mc animated:YES completion:nil];
        
        
    }else{
        
    }
}

//在短信界面操作后，会触发这个代理方法
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    switch (result)
    {
        case MessageComposeResultSent:
