我试图在键盘出现时向上移动布局，因为它隐藏了我的输入文本字段，但我的应用程序从 HASH_FIND_PTR(_targets, &tmp, element); 行崩溃 从这堂课

void ActionManager::addAction(Action *action, Node *target, bool paused)
{
    CCASSERT(action != nullptr, "");
    CCASSERT(target != nullptr, "");

    tHashElement *element = nullptr;
    // we should convert it to Ref*, because we save it as Ref*
    Ref *tmp = target;
    HASH_FIND_PTR(_targets, &tmp, element); //error
    if (! element)
    {
        element = (tHashElement*)calloc(sizeof(*element), 1);
        element->paused = paused;
        target->retain();
        element->target = target;
        HASH_ADD_PTR(_targets, target, element);
    }

     actionAllocWithHashElement(element);

     CCASSERT(! ccArrayContainsObject(element->actions, action), "");
     ccArrayAppendObject(element->actions, action);

     action->startWithTarget(target);
}

我正在使用 cocos2d-x 3.2 我有调试，它在这行 m_pLayout->runAction(moveBy); 之后崩溃 任何人请给我一些建议我该如何解决谢谢

我的登录场景.h

#include "cocos2d.h"
#include "cocos-ext.h"
#include "CocosGUI.h"

USING_NS_CC_EXT;
using namespace ui;

class LoginScene : public Scene
{
public:
    LoginScene(bool pPortrait=false);
    ~LoginScene();

    virtual void onEnter();
    virtual void onExit();

    void onLogin(Ref* pSender, Widget::TouchEventType type);
    void onRegister(Ref* pSender, Widget::TouchEventType type);
