代码：
getUrlRespDataJson_async(
.POST,
url: ServerApi.registerUrl(),
parameters: [
"dealer" : dealer,
"phone" : phone,
"password" : password,
"code" : code,
],
respJsonHandler: { respDataJson in
gLog.info("respDataJson=\(respDataJson)")
NSNotificationCenter.defaultCenter().postNotificationName(kRegisterComplete, object: respDataJson)
})
func getUrlRespDataJson_async(httpMethod:Alamofire.Method, url:String, parameters: [String : AnyObject]? = nil, headers: [String : String]? = nil, respJsonHandler: (Alamofire.Result<JSON, NSError>) -> Void) {
}
public enum Result<Value, Error : ErrorType> {
case Success(Value)
case Failure(Error)
/// Returns `true` if the result is a success, `false` otherwise.
public var isSuccess: Bool { get }
/// Returns `true` if the result is a failure, `false` otherwise.
public var isFailure: Bool { get }
/// Returns the associated value if the result is a success, `nil` otherwise.
public var value: Value? { get }
/// Returns the associated error value if the result is a failure, `nil` otherwise.
public var error: Error? { get }
}
出错：
Cannot convert value of type ‘Result<JSON, NSError>’ to expected argument type ‘AnyObject?’
即，想要把：
Result<JSON, NSError>
当做AnyObject的类型的参数传递，结果不支持。
换成：
NSNotificationCenter.defaultCenter().postNotificationName(kRegisterComplete, object: nil, userInfo: ["respDataJson" : respDataJson])
也不行，同样错误。

How to convert Tuple to AnyObject in Swift – Stack Overflow
答案是：
没法把tuple类型变量转换为AnyObject
－》除非用workaround，借用新建一个类，成员变量是原先的tuple
－》就搞得太复杂了。。。
－》不这样弄了。
ios – Pass Tuples as AnyObject in swift – Stack Overflow
－》只能自己想办法：
把tuple，转换为dict去传递。。。
［总结］
swift和oc中，都不支持把：
Result<JSON, NSError>
类型的变量，即tuple类型的变量，作为AnyObject去传递值。
－》所以此处只能放弃此种用法，该放到新建类，或者改为dictionary的方式去传递值了。
