如何在Swift 2中将Array <string>添加到Dictionary <string，anyobject =“”>

Question

解决！请参阅本文底部的解决方案

我尝试使用Alamofire创建一个JSON对象用于我的后端。我能够添加一个带有String值的键，但似乎无法将Array的值添加到AnyObject。我虽然会非常直接，但我还没能找到解决方案。

func someFunction(btn: UIButton){

        var someDictionary = Dictionary<String, AnyObject>()
        let someArray = [textField[1].text,textField[2].text,textField[3].text]
        someDictionary["answer"] = textField[0].text
        someDictionary["options"] = someArray as? Array // <---- Can't be assigned to AnyObject

        let url = "http://localhost:3000/api/question"
        Alamofire.request(.POST, url, parameters: someDictionary).responseJSON { response in
            if let JSON = response.result.value as? Dictionary<String, AnyObject>{   
            }
        }

 }

解决方案：删除as? Array并创建循环以附加已初始化的数组

func someFunction(btn: UIButton){



        var someDictionary = Dictionary<String, AnyObject>()
        var SomeArray = [String]()
        for i in 1...3{                          //created loop to append the textField text
            SomeArray.append(textField[i].text!)
        }
        someDictionary["answer"] = textField[0].text
        someDictionary["options"] = SomeArray // Removed "as? Array"
        let url = "http://localhost:3000/api/question"
        Alamofire.request(.POST, url, parameters: someDictionary).responseJSON { response in
            if let JSON = response.result.value as? Dictionary<String, AnyObject>{
                print("JSON Response From Server-->\(JSON)")


            }
        }

    }

清理项目并再次运行。您的代码对我有用，我可以分配

func someFunction(btn: UIButton){

    var someDictionary = Dictionary<String, AnyObject>()
    let someArray = ["SomeString","SomeString","SomeString"]
    someDictionary["answer"] = textFields[0].text
    someDictionary["options"] = someArray // now you can assign

    let url = "http://localhost:3000/api/question"
    Alamofire.request(.POST, url, parameters: someDictionary).responseJSON { response in
        if let JSON = response.result.value as? Dictionary<String, AnyObject>{
        }
    }

}
