从 JSON 数组中获取字段并显示在 UIPickerView Swift 中

Question

我的API有一个这样的JSON响应：

SUCCESS: {
data =     (
            {
        addressDescription = "";
        addressLine1 = "30 xxx Street";
        addressLine2 = xxx;
        addressLine3 = "";
        addressType = 1;
        city = Lagos;
        country = Nigeria;
        id = xxx;
        state = Lagos;
    },
            {
        addressDescription = "AAA";
        addressLine1 = "11 bbb Street,";
        addressLine2 = "Ikeja";
        addressLine3 = "";
        addressType = 1;
        city = Lagos;
        country = Nigeria;
        id = xxx;
        state = Lagos;
    }
);

我的 Swift 代码看起来像这样：

var productsArray = [AnyObject]()
Alamofire.request(URL).responseJSON {
        response in
        //printing response
        print(response)
        //getting the json value from the server
        let result = response.result
        if let dict = result.value as? Dictionary<String,AnyObject> {
            if let innerDict = dict["data"]{
                self.addyArray = innerDict as! [AnyObject]
            }
        }
    }

如何让此数组中的各个字段(addressLine1、addressLine2 等(显示在我的 UIPickerView 中？任何帮助将不胜感激。

Answer 1

您可以使用

此功能从Dictionary获取所有keys。

self.addyArray.first.keys //return array of keys

或

self.addyArray[0].keys //return array of keys

确保您的数组不为空。

Answer 2

假设您按照上述 json 结构正确获得结果。

    guard let dictRes = result as? [String : Any] else {
        print("No data")
        return
    }
    guard let data = dictRes["data"] as? [Any] else {
        return
    }
    for value in data {
        let dictData = value as? [String : Any]
        print("addressDescription : (dictData!["addressDescription"])")
        print("addressLine1 : (dictData!["addressLine1"])")
        print("addressLine2 : (dictData!["addressLine2"])")
        print("addressLine3 : (dictData!["addressLine3"])")
    }

Answer 3

Alamofire.request(URL).responseJSON {
        response in
        //printing response
        print(response)
        //getting the json value from the server
        let result = response.result
        if let dict = result.value as? Dictionary<String,AnyObject> {
            if let innerDict = dict["data"]{
               for val in 0..<innerDict.count { 
                let dic = innerDict as! [String, AnyObject]
                  for vals in dic {
                    print(vals)
                    productsArray.append(vals) 
                  } 
               }
            }
        }
    }
