1.封装网络(使用SDWebImage和AFNetworking框架)下载图片

程序启动的时候就会调用,需要先在这个方法中开始监测网络

1.每个cell之间有固定的间距

cell样例

###在自定义cell的.m文件中重写：

- (void)setFrame:(CGRect)frame
{
    frame.size.height -= XMGMarin;

    [super setFrame:frame];
}

By

XYConst.h文件中声明（学习官方常量的定义）

#import <UIKit/UIKit.h>

/** 导航栏的最大Y值 */
UIKIT_EXTERN CGFloat const XYNavMaxY;

/** 标题栏的高度 */
UIKIT_EXTERN CGFloat const XYTitlesViewH;

/** tabBar的高度 */
UIKIT_EXTERN CGFloat const XYTabBarH;

/** 全局统一的间距 */
UIKIT_EXTERN CGFloat const XYMargin;

/** tabbarbutton重复点击 */
UIKIT_EXTERN NSString * const XYTabBarButtonDidClickRepeatNotification;

/** 标题按钮重复点击 */
UIKIT_EXTERN NSString * const XYTitleButtonDidRepeatClick;

XYConst.m中实现

#import <UIKit/UIKit.h>

/** 导航栏的最大Y值 */
CGFloat const XYNavMaxY = 64;

/** 标题栏的高度 */
CGFloat const XYTitlesViewH = 35;

/** tabBar的高度 */
CGFloat const XYTabBarH = 49;

/** 全局统一的间距 */
CGFloat const XYMargin = 10;

/** tabbarbutton重复点击 */
NSString * const XYTabBarButtonDidClickRepeatNotification =     @"XYTabBarButtonDidClickRepeatNotification";

/** 标题按钮重复点击 */
NSString * const XYTitleButtonDidRepeatClick = @"XYTitleButtonDidRepeatClick";

1.需要安装的应用程序

  • node.js 地址

  • 集成git，安装xcode即可

  • 安装hexo

    终端输入 $ sudo npm install -g hexo-cli（sudo 执行管理员权限）

2.使用Hexo来显示博客

创建一个文件夹（blogxxx）（所有命令都是在该文件中）
  • 进入到根目录执行命令
    • cd blogxxx
    • hexo init
    • npm install
    • hexo s (运行hexo,以后要在本地运行博客只要输入该命令即可)
    • Ctrl+C(停止运行)

配置_config.yml文件

(1).显示图片的方法，使用asset-image：
  • cd到文件目录下，执行 npm install https://github.com/CodeFalling/hexo-asset-image –save
  • 修改_config.yml 中有 post_asset_folder:true
  • 在source/_posts中创建一个xxx.md文件同名的文件夹xxx,该xxx文件夹放入xxx.md文件中使用到的图片,在xxx.md中引用图片方式为：![图片名称](xxx/图片名称带格式后缀)
(2).主题
  • git clone https://github.com/wuchong/jacman.git themes/jacman
    • jacman文件夹下，从终端进入删除掉相关的.git和.gitignore文件
    • 在_config.yml文件中搜索theme，将theme：xxx设置为 theme： jacman（主题名）

3.关联github仓库的链接

  • 在_config.yml文件中 ，将deploy改为
    • type: git
    • repository: 仓库链接
    • branch: master（分支）

###关键步骤：关联命令

  • npm install hexo-deployer-git –save

设置url

  • 在 _config.yml 文件中的 http://yoursite.com 替换为 http://仓库名.github.io

hexo 相关命令

设置git身份信息

  • git config –global user.name “你的用户名”

  • git config –global user.email “你的邮箱”

  • hexo clean 清理

  • hexo g 生成静态站点(位于public目录)
