请原谅我对 Swift 还很陌生。我想创建一个用于“POST”请求并从服务器获取响应的委托。然后将从服务器返回的参数传递给 func 并允许我的主类做出相应的响应。下面是我的代表和我的主要课程。它没有打印 LoginViewController 类中的响应日志。我有点迷失了，不太知道哪里出了问题。非常感谢有关如何使其发挥作用或更好的方法的建议/指示。谢谢！

import Alamofire
protocol ServletDelegate {
func responseSuccess(sender: Servlet, respArray : [String])
func responseFail(sender: Servlet, respArray : [String])
}
class Servlet : UIViewController{
var delegate:ServletDelegate?
//form 'data' parameter
Alamofire.request(.POST, Config.flURL, parameters:["data" : ""]).responseData {
response in
print ("request \(response.request)")
print ("response \(response.response)")
print ("result \(response.result)")
print ("data \(response.data)")
let responseData = NSString (data: response.data!, encoding: NSUTF8StringEncoding)
result = (responseData?.componentsSeparatedByString("~z0@"))!
print("responseData :\(responseData)");
print("result :\(result)");
self.delegate?.responseSuccess(self, respArray: result);
}

class LoginViewController: Servlet, UITextFieldDelegate, ServletDelegate {
@IBAction func submitBtnAction(sender: UIButton) {
Servlet().LoginUserHttp(tfUsername.text!, userPassword: tfPassword.text!);
}
func responseSuccess(sender: Servlet, respArray: [String]) {
print("responseSuccess: \(respArray)");
}
func responseFail(sender: Servlet, respArray: [String]) {
print("responseFail: \(respArray)");
}
}
首先，您的 servlet 类不应该是 UIViewController，其次 - 不要使用 ;很快它是多余的，第三你没有设置委托，第四是委托应该很弱，这样你就不会遇到强引用循环，第五我没有看到传递发送者的理由
顺便说一句，您可能应该通过响应失败委托传递一些错误对象，但这取决于您
