ios - MFMessageComposeViewController 错误地聚焦在字段上

Question

我正在实现通过短信邀请 friend 的可能性，但出现了小问题。问题与对该领域的错误关注有关。

下图描述了问题:

因为可以看到焦点在单词“кому:”之前而不是之后。

所以请有人帮助我了解如何在 MFMessageComposeViewController 中设置适当的焦点。

显示短信 View 的代码如下:

if ([MFMessageComposeViewController canSendText])
{
            MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc] init];
            [messageController setBody:@"I'm on Memry, come join me! =) \n https://itunes.apple.com/us/app/memry/id735465896?mt=8"];
            messageController.navigationBar.titleTextAttributes = @{
                                                                   NSForegroundColorAttributeName: [UIColor blackColor],
                                                                   };
            messageController.messageComposeDelegate = self;
            [self.view.window.rootViewController presentViewController:messageController animated:NO completion:nil];
            [messageController release];
        }
        else
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Memry"
                                                            message:@"Your device does not support SMS"
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
            [alert show];
            [alert release];
}

    MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc] init];
    [messageController setRecipients:@[@"+86 15011582532"]];
    [messageController setBody:@"I'm on Memry, come join me! =) \n https://itunes.apple.com/us/app/memry/id735465896?mt=8"];
    messageController.navigationBar.titleTextAttributes = @{
                                                            NSForegroundColorAttributeName: [UIColor blackColor],
                                                            };
    messageController.messageComposeDelegate = self;
    [self.view.window.rootViewController presentViewController:messageController animated:NO completion:nil];
