無法在Swift 3中從模型類獲取數據？

Question

這是模型類的數據，在其中我從所有詞典中獲取了數據，但無法獲得評級從模型類中獲得的投票中，我需要獲取value鍵值對以用於在UI中顯示評級，誰能幫我解決這個問題？

func ReviewApiDownloadJsonwithURL(reviewApi : String){
            print(reviewApi)
            let url = URL(string: reviewApi)!
            let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
                if error != nil { print(error!); return }
                do {
                    if let jsonObj = try JSONSerialization.jsonObject(with: data!) as? [[String:Any]] {
                        for item in jsonObj {
                             self.reviewModel = Review.init(dict: item)
                        }
                        DispatchQueue.main.async {
                            guard let obj = self.reviewModel else { return }
                            let itemsCount = obj.reviews
                            for i in 0..<itemsCount.count {
                                let customAttribute = obj.reviews[i].ratingVotes
//                                for j in 0..<customAttribute.count {
                                        self.ratingvalue.append(customAttribute[0].value!)
//                                }
                            }
                            print(self.ratingvalue)
                            self.reviewTableView.delegate = self
                            self.reviewTableView.dataSource = self
                            self.activityIndicator.stopAnimating()
                            self.activityIndicator.hidesWhenStopped = true
                            self.reviewTableView.reloadData()
                            self.initialCollectionData()
                        }
                    }
                } catch {
                    print(error)
                }
            }
            task.resume()
    }

這是我的Json數據

這是我的模型類代碼

struct Review  {

    let ratingPercent : Any?
    let count : Any?
    let reviews : [Reviews]


    init(dict : [String:Any]) {
        if let customAttribute = dict["reviews"] as? [[String: AnyObject]] {
            var result = [Reviews]()
            for obj in customAttribute {
                result.append(Reviews(dict: (obj as? [String : Any])!))
            }
            self.reviews = result
        } else {
            self.reviews = [Reviews]()
        }
        self.ratingPercent = dict["avg_rating_percent"]
        self.count = dict["count"]
    }
}

struct Reviews {

    init(dict : [String:Any]) {
        if let customAttribute = dict["rating_votes"] as? [[String: Any]] {
            var result = [RatingVotes]()
            for obj in customAttribute {
                result.append(RatingVotes(dict: (obj as? [String : Any])!))
            }
            self.ratingVotes = result
        } else {
            self.ratingVotes = [RatingVotes]()
        }
        self.reviewId = dict["review_id"]
        self.createdAt = dict["created_at"]

            self.ratingCode = dict["rating_code"] as? String
            self.storeId = dict["store_id"] as? Int
            self.code = dict["code"] as? Int
            self.postion = dict["position"] as? Int

        }
}

Answer 1

您可能會復制粘貼代碼，這只是Typo錯誤。 您可以通過調試輕松找到它，這是您犯的一個小錯誤

在struct Reviews觀察

   if let customAttribute = dict["reviews"] as? [[String: Any]] {
        var result = [RatingVotes]()
        for obj in customAttribute {
            result.append(RatingVotes(dict: (obj as? [String : Any])!))
        }
        self.ratingVotes = result
    } else {
        self.ratingVotes = [RatingVotes]()
    }

您在此處使用關鍵reviews dict["reviews"]

應該像dict["rating_votes"]一樣為rating_votes

希望對您有幫助

Answer 2

您將兩個時間查看字典的值都設為相同。 如果讓customAttribute = dict [“ reviews”]為？ [[String：Any]所以在這里將'review'更改為'rating_votes'

或者按照下面的代碼可能會幫助您！

init(dict : [String:Any]) {
    if let customAttribute = dict["rating_votes"] as? [[String: Any]] {
        var result = [RatingVotes]()
        for obj in customAttribute {
            result.append(RatingVotes(dict: (obj as? [String : Any])!))
        }
        self.ratingVotes = result
    } else {
        self.ratingVotes = [RatingVotes]()
    }
    self.reviewId = dict["review_id"]
    self.createdAt = dict["created_at"]
    self.entityId = dict["entity_id"]
    self.entityValue = dict["entity_pk_value"]
    self.statusId = dict["status_id"]
    self.detailId = dict["detail_id"]
    self.title = dict["title"] as? String
    self.detail = dict["detail"] as? String
    self.nickName = dict["nickname"] as? String
    self.customerId = dict["customer_id"]
    self.entityCode = dict["entity_code"]
 }
}
