Question

我的API中有这样的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代码如下所示：

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]
            }
        }

    }

如何获取此数组中的各个字段（addressLine1，addressLine2等）以显示在我的UIPickerView中？任何帮助将不胜感激。

Answer 1

您可以使用此keys从Dictionary获取所有self.addyArray.first.keys //return array of keys。

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

或

class MyCell: FSPagerViewCell{


}

确保您的阵列不为空。

Answer 2

假设你按照上面提到的json结构正确得到了结果。

filename = forms.FileField(label='Select a file')

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) 
                  } 
               }
            }
        }

    }

从JSON数组中获取字段并在UIPickerView Swift中显示
