我在Xcode文件夹中使用第三方GitHub库。它让我可以访问Yelps API，我想在我的应用程序中获取搜索结果。我成功下载将数据转换为JSON字符串。
但我坚持解码JSON字符串的逻辑，以便我可以访问实际参数，例如name，display_address和price。我之前使用过“Decode”，但从未通过第三方库。我确信这是可能的，我可能只是一步或两步之遥，但我现在缺乏经验阻碍了这一点。任何帮助。谢谢
这是我获取JSON数据的函数，下面是我得到的响应
func getYelp() {
let yelpAPIClient = CDYelpAPIClient(apiKey: "MY_API_KEY")
yelpAPIClient.cancelAllPendingAPIRequests()
CDYelpFusionKitManager.shared.apiClient = yelpAPIClient
CDYelpFusionKitManager.shared.apiClient.searchBusinesses(byTerm: "Bars",
location: "Hollywood, California",
latitude: nil,
longitude: nil,
radius: 10000,
categories: [CDYelpBusinessCategoryFilter.bars],
locale: CDYelpLocale.english_unitedStates,
limit: 5,
offset: 0,
sortBy: CDYelpBusinessSortType.distance,
priceTiers: [CDYelpPriceTier.twoDollarSigns],
openNow: true,
openAt: nil,
attributes: nil) { (response) in
if let response = response,
let businesses = response.businesses?.toJSONString(),
businesses.count > 0 {
print(businesses)
}
}
}

第三方库已经为您完成了所有解码。不要将响应转换回JSON字符串。
response.businesses是CDYelpBusiness个对象的数组，其定义如下：
public var id: String?
public var name: String?
public var imageUrl: URL?
public var isClosed: Bool?
public var url: URL?
public var price: String?
public var phone: String?
public var displayPhone: String?
public var photos: [String]?
public var hours: [CDYelpHour]?
public var rating: Double?
public var reviewCount: Int?
public var categories: [CDYelpCategory]?
public var distance: Double?
public var coordinates: CDYelpCoordinates?
public var location: CDYelpLocation?
public var transactions: [String]?
尝试迭代它们并访问它们的属性，如下所示：
for business in response.businesses {
print(business.name)
}
