fail to work with yasnippet

[richarddwang]

*Sorry for don't know how to post an issue correctly and my poor English, If there are somewhere goes wrong /can do better, please give me a chance to apologize and fix it next time

I would like to integrate yasnippet's suggestions into company's pop suggestion menu every where. I use Irony-mode and company-Irony company-irony-c-headers

way1.from the only answer of a question on stack exchange http://emacs.stackexchange.com/questions/10431/get-company-to-show-suggestions-for-yasnippet-names ---->don't work

way2.from https://gist.github.com/nonsequitur/265010 ---->don't work

way3.from http://stackoverflow.com/questions/2087225/about-the-fix-for-the-interference-between-company-mode-and-yasnippet ----->don't work

finally, I use

(eval-after-load 'company
  '(add-to-list
    'company-backends '( company-irony-c-headers company-irony company-yasnippet)))

and sucessfully realize both company and yasnippet's suggestions show on the pop menu but.....only in irony-mode(only active in my .cc), and in global(like .el) yasinippet completely overlap comany and I can't see its suggestion or TAB to complete when there's only one candidate

[note] this is my confiquration part for company-mode from my Completion.el and Irony.el Completion.el

;;********
;; enable

 (require 'company)
(add-hook 'after-init-hook 'global-company-mode)
;;*******************
;; confiqure company
;;*******************
;; company-idle-delay:company delay until suggestions are shown
;;     (nil will cause completion menu don't pop automatically)
;; company-transformers...: weight by frequency

(setq company-idle-delay              0
      company-minimum-prefix-length   2
      company-show-numbers            t
      company-tooltip-limit           20
      company-dabbrev-downcase        nil
      company-transformers '(company-sort-by-occurrence)
      company-dabbrev-other-buffers   t
      )

;;**************************
;; Load as a grouped backend
;;**************************
;; company-irony-c-header : It must be loaded after irony-mode, while the backend should be grouped with company-irony, and before it. (so I try to put company-yasnippet into the group, and finally integrated yasnippet into completion pop menu!!!!!!!)
;; caution!!! company-yasnippet overlap company-mode in global
(eval-after-load 'company
  '(add-to-list
    'company-backends '( company-irony-c-headers company-irony company-yasnippet)))

Irony.el

;; =============

my emacs confiquration https://github.com/frankie8518/Emacs_super_configuration

Is there any good solution or suggestion to show both yasinippet and company's suggestions on pop menu?
