单身人士在不同平台上摧毁

Question

此代码在Windows和Linux中完美运行，但在Android中不调用appCfg :: ~appCfg（）。如何修改代码以在所有平台上自动销毁appCfg（在关闭程序中）？

的.cpp

private void ComboBoxCompaniesSelectionChanged(object sender, SelectionChangedEventArgs e)
{
    Client client = e.AddedItems[0] as Client;
    if (client != null)
    {
        TruckServiceClient tsc = null; // ...
        List<Representative> representatives = GetRepByComp(tsc, client.Id.ToString());
        comboBoxRepresentatives.ItemsSource = representatives;
    }
}

Answer 1

所有代码都不合适，所以我在这里写下其余的代码

·H

class SingletonDestroyer
{
private:
    appCfg* p_instance;
public:   
    ~SingletonDestroyer();
    void initialize( appCfg* p );
};

class appCfg : public QObject
{
private:
    static appCfg* p_instance;
    static SingletonDestroyer destroyer;

    QSettings * pSetting;
protected:
    appCfg();
    appCfg( const appCfg& );
    appCfg& operator=( appCfg& );
    ~appCfg();
    friend class SingletonDestroyer;
public:
    static appCfg& getInstance();
   ...
};
