arrays - 如何在本地数组 swift 3 中保存来自 Alamofire 的 response.result.value

Question

Alamofire.request(NEWS_FEED_URL).responseJSON { response in

guard let newsResponse = response.result.value else{
        print("Error: \(response.result.error)")
        return
    }
    print("JSON: \(newsResponse)")
    let localArray:Array = [newsResponse]
    print("Local Array:", localArray)
}



I am using alamofire to fetch data from server and trying to write parser on the response data. When I fetch response.result.value from alamofire and print it is working fine. But as soon as I put response.result.value in my local array it gives  


[<__NSArrayI 0x6080000bcf80>(
{
    category = World; 
})]

以此类推(控制台)。此外，我无法将“Any”类型的响应值转换为“Array”。请帮助我如何在“Array”类型的本地数组中添加 response.result.value。有人可以简要解释一下在 alamofire 上进行类型转换吗？

您只需将 response.result.value 的结果转换为字典数组。

guard let newsResponse = response.result.value as? [[String:String]] else{
    print("Error: \(response.result.error)")
    return
}
print("JSON: \(newsResponse)")
let localArray = newsResponse
//Access the localArray
print("Local Array:", localArray)
//Now to get the desired value from dictionary try like this way.
let dic = localArray[0]
let title = dic["title"] ?? "Default Title"
let link = dic["link"] as? "Default link"
//... get other value same way.

注意:您的响应已经是一个数组，所以不要通过将它添加到另一个数组中来从中创建数组。
