swift 3 : Pass in the indexPath into another Class

Question

我有一个返回帖子数组的collectionView，[Post]。在 collectionViews 单元类(实际的帖子)内部，我有一个名为 profileSegueContainer 的 View 。 isUserInteractionEnabled 当然设置为 true，并且我有一个 UITapGestureRecognizer，它在点击此 View 时运行一个函数。这个函数只是呈现另一个ViewController。我希望当我点击 profileSegueContainer 时能够将 post.uid 传递到此 ViewController 中。我该如何实现这一目标？谢谢。相关代码如下。任何建议将不胜感激...

class Post: NSObject {

    var author: String?
    var avatar_image_url: String?
    var likes: Int?
    var postImageUrl: String?
    var uid: String?
    var post_id: String?
    var hashtags: [String]?
}

class PostCell: BaseCell {

    var homeController: HomeController?

    lazy var profileSegueContainer: UIView = {
        let view = UIView()
        view.isUserInteractionEnabled = true
        return view
    }()

    override func setupViews() {
        super.setupViews()

        let tap = UITapGestureRecognizer(target: self, action: #selector(handleProfileSegue))
        profileSegueContainer.addGestureRecognizer(tap)

       topBar.addSubview(profileSegueContainer)
    }

    func handleProfileSegue() {
        let userProfileController = UserProfileController()
        let navigationUserProfileController = UINavigationController(rootViewController: userProfileController)
        homeController?.present(navigationUserProfileController, animated: true, completion: nil)
    }
}

希望我正确理解您的问题。您想将值传递到新的 UserProfileController 对象中吗？

向您的 UserProfileController 添加属性

class UserProfileController : UIViewController {
    public var postId : Int!
// more stuff ....
}

然后，您只需在创建对象后访问该属性即可:

func handleProfileSegue(sender: UITapGestureRecognizer) {
  let userProfileController = UserProfileController()
    userProfileController.postId = 2345
    // more stuff...
}

请告诉我这是否是您所需要的。如果没有，我们将更新我们的帖子。
