通用调用实现方法

Question

如果我知道他的参数，我可以调用实现方法。例如

let method: Method = class_getInstanceMethod(owner.dynamicType, selector)
let implementation = method_getImplementation(method)
// if i known this ((String, String) -> NSString)
typealias Function = @convention(c) (AnyObject, Selector, String, String) -> Unmanaged<NSString>
let function = unsafeBitCast(implementation, Function.self)
let result = { title, message in function(owner, selector, title, message).takeUnretainedValue() }

但该怎么办，如果我以前不知道方法的类型？我能做点什么吗？也许可以将参数告诉为数组？
