> --------------------------------------------------------
>
> Key: WEEX-200
> URL: https://issues.apache.org/jira/browse/WEEX-200
> Project: Weex
> Issue Type: Bug
> Components: iOS
> Reporter: xingZhang
> Assignee: xingZhang
> Priority: Major
>
> As iOS developers knows, we cannot distinguish the block by its params
> count, but it has been a time we use the default value of block parameter, I
> find out that the default value could be dirty data.
>
> here is the callback type definition.
> typedef void (^WXCallback)(_Nonnull id result)
> typedef void (^WXKeepAliveCallback)(_Nonnull id result, BOOL keepAlive);
>
> when the method called, weexSDK will set the callback according to the
> @encode result,
> but these two type's encode result are all "?", see more encode result from
> Apple Documents
> [https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/ObjCRuntimeGuide/Articles/ocrtTypeEncodings.html]
