天猫首页UI层次与类设计分析

　　电商APP的首页设计和实现，直接关系到对用户跳出率与最后的购买转换率。使用过天猫iPhone客户端的童鞋，一定能感受到其良好的用户体验和交互流畅。作为电商行业的佼佼者，以及具有移动端开发多年的沉淀，天猫在首页的UI层次与类设计是怎样的呢，笔者使用越狱iPad、ida、Reveal、dumpdecrypted、class-dump等工具对该页面作了分析，给出主要的头文件以及一些Reveal截图，供大家参考。

一、逆向文件整理

　　其中Tmall4iPhone.app为未脱壳前的文件，但可以从里面的文件看出，其对各资源文件有良好的命名，以及用到了多个阿里组件SDK；Tmall4iPhone.h为app所有的头文件；FrontPage_all.h为首页相关的头文件；FrontPage_main.h为首页重要的几个头文件，也将在本文第四节中给出。在截图中呈现的大部分为自定义View类，头文件可以在Tmall4iPhone.h中搜索，了解其定义声明。

　　https://github.com/1962449521/TmallFrontPage_Crack

二、由头文件及Reveal UI层次得出的猜想

　　1. 内容容器并非直观认为的TableView，而是使用了ScrollView，但几乎实现了与tableView相同的数据源、重用机制等特点。

　　2. 数据分段加载，总数据分成多段批次向服务器请示，ScrollView的contentSize随逐次数据请求而递增。

　　3. 每批次获取数据后，生成各个小节的数据实例及UI实例，将UI加入到ScrollView。

　　4. 各小节的数据实例由canResue属性决定是否能做内存重用。

　　5. 首页有隐藏的WebView以处理线上Bug，配合大促实时维护，或做一些类似红包雨、弹幕墙的活动。

三、 Reveal UI分析

　　1. 容器组成分析

　　* 由UITabBar可以了解到多Tab App常用的TabBarController.

　　* FrontPageTopBar为页头的扫描、搜索消息等。页面滑至顶部时背景透明，滑离顶部时背景为红色。非第一次使用App, 页面DidAppear时，页面会自动滑动到中间的推荐部位。

　　* 有隐藏的PopLayer,内含hybrid的webView,猜测用于大促时的动态监控与实时修复，或是红包雨、弹幕墙等活动。

　　2. 一些小控件

　　3.主要内容容器TMFrontPageLazyScrollView

　　3. 剩余部分主要是目录树或者穿插其中的静态广告栏

四、较为关键的头文件：首页视图控制器ViewController、内容容器ScrollView、单项内容数据模型与ViewModel

　　1.首页视图控制器ViewController
