Question

我得到了＆＃34; 16＆＃34;从我的关键＆＃34;价值＆＃34;在tax_ncurrency中。我使用Alamofire处理json，但我不能将它分配给我的标签：productTax

    ["data": (
        {
        "tax_n_currency" =         {
            Value = 16;
            Variable = Tax;
        };
    },
        {
        "tax_n_currency" =         {
            Value = USD;
            Variable = Currency;
        };
    }
)]

我的要求。

     Alamofire.request(.GET, url!, parameters: ["accesskey":223344666]).responseJSON { (request, response, result) in

         let json = result.value as! [String:AnyObject]
        print(json)
        let data = json["data"] as! [AnyObject]
        //print(mm)

        let taxnCurrency = data[0]["tax_n_currency"] as! NSDictionary
        print(taxnCurrency)

        if let tax = taxnCurrency["Value"]?.intValue{
            self.productTax.text = "\(tax) %"
            print(tax)
        }
    }

Answer 1

尝试：

if let tax = data["data"] as? [AnyObject],
        tax_n_currency = tax["tax_n_currency"] as? [String:AnyObject],
        value = tax_n_currency["Value"] as? Int {
    print(value)
}

Answer 2

我喜欢使用if语句检查变量是否真的设置，您可以使用print来检查是否在if语句中获取。如果这不起作用，请提供有关JSON的更多信息。编辑：将第一个条件更改为Dict数组

 Alamofire.request(.GET, url!, parameters: ["accesskey":223344666]).responseJSON { (request, response, result) in
        var taxnCurrency: Integer!
        let json = result.value as! [String:AnyObject]
        let data = json["data"] as! [[String:AnyObjecy]]

        if let dict = json[0]["tax_n_currency"] {
                      if let tax = dict["Value"] as! Integer {
                          taxnCurrency = tax
                      }
                   }
