app跳转到短信发送编辑

跳转到手机短信编辑界面

 Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));
                if (messageClass != nil) {
                    if ([messageClass canSendText]) {//首先判断手机是否能进行编辑
                        //打开手机的短信编辑控制器
                        MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
                        picker.messageComposeDelegate = self;
                        //传出去的分享内容
                        picker.body = [NSString stringWithFormat:@"%@",showmeg];
                        [self presentViewController:picker animated:YES completion:nil];
                    } else {
                        UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"当前设备暂时没有办法发送短信" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定",nil];
                        [myAlertView show];
                    }
                }

代理方法的实现

#pragma mark MFMessageComposeViewControllerDelegate

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller
                 didFinishWithResult:(MessageComposeResult)result
{
    // Notifies users about errors associated with the interface
    switch (result) {
        case MessageComposeResultCancelled:
            //用户自己取消，不用提醒
            break;
        case MessageComposeResultSent:
            //后续可能不能够成功发送，所以暂时不提醒
            break;
        case MessageComposeResultFailed:
            NSLog(@"短信发送失败");
            break;
        default:
            NSLog(@"短信没有发送");
            break;
    }
    [self dismissViewControllerAnimated:YES completion:nil];
}
