crash - (cocos2d-x for iOS) UITextField 在输入时有时会崩溃

Question

我在 cocos2d-x 项目中添加了 UITextField。但是当输入时，应用程序有时会崩溃。
请给我一些帮助，谢谢。
这是我的代码

   m_textField = [[UITextField alloc] initWithFrame:CGRectMake(TEXT_FIELD_POSX, TEXT_FIELD_POSY, TEXT_FIELD_WIDTH, TEXT_FILED_HEIGHT)];
    m_textField.tag = CHAT_TEXT_TAG;
    m_textField.delegate = (AppController *)clientApp.delegate;
    [m_textField setBackgroundColor:[UIColor clearColor]];
    [m_textField setTextColor:[UIColor blackColor]];
    [m_textField setFont:[UIFont fontWithName:@"Helvetica" size:14]];
    m_textField.returnKeyType = UIReturnKeySend;
    m_textField.enablesReturnKeyAutomatically = YES;

    [[EAGLView sharedEGLView] addSubview:m_textField];

您应该像这样实现您的委托(delegate)方法:

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    cocos2d::CCEGLView* pglview = cocos2d::CCDirector::sharedDirector()->getOpenGLView();
    if(pglview)
    {
        pglview->setIMEKeyboardState(false);
    }
    return YES;
}

希望它会有所帮助:)。
