[jira] [Created] (WEEX-200) deprecate WXCallback and WXModuleCallback callback type

xingZhang created WEEX-200:
------------------------------

             Summary: deprecate WXCallback and WXModuleCallback callback type 
                 Key: WEEX-200
                 URL: https://issues.apache.org/jira/browse/WEEX-200
             Project: Weex
          Issue Type: Bug
          Components: iOS
            Reporter: xingZhang
            Assignee: xingZhang


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]
