這是我的.vimrc

"========================== 
"vundle 
set nocompatible " be iMproved

" set the runtime path to include Vundle and initialize 
set rtp+=~/.vim/bundle/Vundle.vim

" alternatively, pass a path where Vundle should install plugins 
"call vundle#begin('~/some/path/here') 
" let Vundle manage Vundle, required 
Plugin 'VundleVim/Vundle.vim'  
" The following are examples of different formats supported. 
" Keep Plugin commands between vundle#begin/end. 
"====================== 
" plugin on GitHub repo 
"====================== 
" For GitHub repos, you specify plugins using the 'user/repository' format 
Plugin 'Valloric/YouCompleteMe'

"color schemes

"======================== 
" All of your Plugins must be added before the following line 
"======================

filetype plugin indent on " required 
" To ignore plugin indent changes, instead use: 
"filetype plugin on  
" Brief help 
" :PluginList - lists configured plugins 
" :PluginInstall - installs plugins; append ! to update or just 
":PluginUpdate 
" :PluginSearch foo - searches for foo; append ! to refresh local cache 
" :PluginClean - confirms removal of unused plugins; append ! to 
" see :h vundle for more details or wiki for FAQ 
" Put your non-Plugin stuff after this line

"" Ultisnips 
let g:UltiSnipsExpandTrigger="<c-tab>" 
let g:UltiSnipsListSnippets="<c-s-tab>" 

結果顯示：在這張照片我的 「FO」 攻絲後。然後，我可以做的是點擊「Tab」從一個選項移動到另一個，問題是我應該點擊什麼來擴展補充「剪輯」一個（[選項卡]不能接受完成，因爲什麼valloric said in user guide）？ 另一個問題是爲什麼我不能讓你完成一個功能，一個班級？在這種情況下，我想我可以完成一個func「fopen」。 是否發生了一些碰撞，因爲這裏有很多插件？

設置此變量的東西適合你的口味：

let g:UltiSnipsExpandTrigger="<c-space>" 
let g:UltiSnipsJumpForwardTrigger="<c-j>" 
let g:UltiSnipsJumpBackwardTrigger="<c-k>"
