objective-c - AnyObject 到 NsDictionery

Question

如何将此javascript数据转换为ios兼容数据并将其放入字典中，当我执行类似newCustomer [“cvc_check”]之类的操作时，我得到一个零，我试图从解析PFCloud.callFunctioninBackground中获取数据这是调用 stripe.com api 来获得这些结果

func hasToken(token: STPToken!) {

var parameters = ["cardToken":token.tokenId,
                  "objectId":PFUser.currentUser().objectId]

    PFCloud.callFunctionInBackground("createCustomer", withParameters:parameters) {
        (results: AnyObject!, error: NSError!) -> Void in
        if !error {

            var newCustomer = results as Dictionary<String, AnyObject>
            println(newCustomer["cvc_check"]) // This gives me a nil

            self.successfulPayment()
        } else {
            let message = error.userInfo["error"] as NSString
            self.hasError("\(message) Please try agains.")
        }
    }

Answer 1

我认为问题出在这条线上：

var newCustomer = results as Dictionary<String, AnyObject>

正如您在评论中所说，结果是一个Array，所以这一行应该是：

var newCustomer = results as Array<Dictionary<String, AnyObject>>

这有帮助吗？
