Swift Alamofire Response のリターン結果待つ Closure利用の例

Closure パラメータの関数を用意

func postRequest( urlSuffix : String, params:[String : AnyObject]?, filterParams : [String]?, 
success: (response: AnyObject!) -> Void, failure: (error: NSError?) -> Void)
{
    Alamofire.request(.POST, webServicesURLPrefix + urlSuffix, parameters: params, encoding: .JSON, headers: self.headers)
    request?.responseJSON { response in
        switch response.result
        {
        case .Success:
            success(response: response.result.value)
        case .Failure(let error):
            failure(error: error)
        }
    }
}

関数を呼び出し

self.postRequest("do-registration.php", params: params, filterParams: nil, success: { (response) -> Void in
        self.afterResponse(response)
        }) { (error) -> Void in
            failure(error: error)
    }
