import AFNetworking
//自定义枚举类型
enum RequestType {
    case GET        //get请求
    case POST       //post请求

class AFNetworkingManager: AFHTTPSessionManager {
    //单例模式 使用闭包对实例进行值设定

    func requestData(requestType: RequestType , urlString :String , parameters :[String : AnyObject]?,returnData : (result : AnyObject?,error : NSError?)->()) {

        }
        
        
    }

调用例子 AFNetworkingManager.shareObject.requestData()

//get 请求
AFNetworkingManager.shareObject.requestData(.GET, urlString: "http://httpbin.org/get", parameters: ["name" : "SongJinwei","age" : 25]) { (result, error) in
            print(result)
        }
//post 请求
AFNetworkingManager.shareObject.requestData(.POST, urlString: "http://httpbin.org/post", parameters: ["name" : "SongJinwei","age" : 25]) { (result, error) in
            print(result)
        }
