Git 仓库结构（一）***

阅读更多关于 Git 仓库结构（一）***

Git 仓库 1.1Git 基本概念在Git中，我们将需要进行版本控制的文件目录叫做一个仓库（repository），每个仓库可以简单理解成一个目录，这个目录里面的所有文件都通过Git来实现版本管理，Git都能跟踪并记录在该目录中发生的所有更新。现在我们已经知道什么是repository（缩写repo）了，假如我们现在建立一个仓库（repo），那么在建立仓库的这个目录中有一个“.git”的文件夹。这个文件夹非常重要，所有的版本信息，更新记录，以及Git进行仓库管理的相关信息全部保存在这个文件夹里面。所以，不要修改/删除其中的文件，以免造成数据的丢失。进一步的讲解请参考下面一张图，大概展示出了我们需要了解的基本知识。　　　　根据上面的图片，下面给出了每个部分的简要说明： Directory：使用Git管理的一个目录，也就是一个仓库，包含我们的工作空间和Git的管理空间。 WorkSpace：需要通过Git进行版本控制的目录和文件，这些目录和文件组成了工作空间，除了.git之外的都属于工作区。 .git：存放Git管理信息的目录，初始化仓库的时候自动创建。 Index/Stage：暂存区，或者叫待提交更新区，在提交进入repo之前，我们可以把所有的更新放在暂存区。 Local Repo：本地仓库，一个存放在本地的版本库；HEAD会只是当前的开发分支（branch）。

问题 I was looking for posts regarding to this, but I don't fully understand... What is the difference between: [context reset]; and: for (NSManagedObjectID *objId in objectIds) { [context deleteObject:[context objectWithID:objId]]; } Or are they equivalent? Thanks 回答1: Using reset puts the managed object context back to the state it was in when you first created it-- before you had performed any fetches, created any new objects, etc. If you have any managed objects in memory that were fetched

variables retaining values after app close

阅读更多关于 variables retaining values after app close

问题 My app is retaining all of the variable values when it closes and this is effecting how it runs when reopened. Is there any way to reset them all upon app close? or is there a way to clean the app from memory when it is closed so to speak? For the moment I have just been setting all of the important variables "=0" in the last few lines of execution but I know there must be a correct way to doing this. EDIT: OK I thought that it would just be easier to reply here instead of individually to

compass常用模块（reset、css3、layout篇）

阅读更多关于 compass常用模块（reset、css3、layout篇）

compass内置五大模块：reset、css3、layout、typography、utilities（官网： http://compass-style.org/reference/compass/ ） 1、reset：浏览器样式重置模块，用来减少不同浏览器之间的差异性 reset把对样式的重置封装成了一个又一个的mixin，通过@import "compass/reset/utilities"来引入这些mixin的集合，有时不需要进行全局的样式重置，可以单独重置某一块。用法： @import "compass/reset/utilities"; @include reset-html5; 可以使用normalize替换掉compass的reset模块 (1)使用包管理工具，npm install normalize.css (2)使用compass的normalize的插件使用命令行指令“gem install compass-normalize” 这里使用第二种方式： 1.在config.rb中引用插件 require 'compass-normalize' 扩展： <1>require 'compass/import-once/activate'用来设置，在不同代码位置，重复引用时只需一次即可，避免代码冗余。实在需要重复引用时加上“！”即可，如 @import
