从我的PrimaryContentViewController和DrawerContentViewController的HomeViewController中设置数据

Question

我使用的是滑轮，在这里我使用下面的代码来打开PulleyViewController。

func openEventInfoPage(event : EventsModel,indexPath:NSIndexPath){
        let vc = storyboard?.instantiateViewController(withIdentifier: "PulleyViewController")
            as! PulleyViewController

        navigationController?.pushViewController(vc, animated: true)
}

在这里，在打开PulleyViewController时，我还需要向DrawerContentViewController和PrimaryContentViewController.发送数据我该怎么做？

在Github上没有提到过，我试着在推动PulleyViewController之前创建类的对象和发送数据，但是它没有工作。提前谢谢。

Answer 1

我拿出了下面的解决方案，效果很好。

    let mainContentVC = storyboard?.instantiateViewController(withIdentifier: "PrimaryContentViewController") as! PrimaryContentViewController

    mainContentVC.event = event
    mainContentVC.indexPath = indexPath

    let drawerContentVC = storyboard?.instantiateViewController(withIdentifier: "DrawerContentViewController") as! DrawerContentViewController
    drawerContentVC.event = event

    let pulleyDrawerVC = PulleyViewController(contentViewController: mainContentVC, drawerViewController: drawerContentVC)
    navigationController?.pushViewController(pulleyDrawerVC, animated: true)

Answer 2

在DrawerContentViewController上添加一个属性。比如- aProperty作为开放属性。并在你的aProperty上分配DrawerContentViewController的价值-

func openEventInfoPage(event : EventsModel,indexPath:NSIndexPath){
        let vc = storyboard?.instantiateViewController(withIdentifier: "PulleyViewController") as! PulleyViewController 
        let vc2 = storyboard?.instantiateViewController(withIdentifier: "DrawerContentViewController") as! DrawerContentViewController

         vc2.aProperty = "value"

        navigationController?.pushViewController(vc, animated: true)
}
