项目想做成电商app平台

基础构想将现有的app维护好，以上一个版本的app为模版创建多个app给租户使用

需求： 1.现有app 为模版里面涉及的有关现有App的图片字样要使用boundle包装起来
并创建一个全局文件替换字样
2.有关推送分享登陆模块创建confige配置文件使租户可以使用自己的账户
3.因为大量租户无须有高度自定义话的内容所以初步模版不考虑配置不同的控件页面样式只需要能替换appid icon name 和一些主题色就好

根据需求思考方案:可以简化开发步骤通过创建多个target创建大量相似项目（可能可以使用脚本替换）

1.png

2.png

3.png

如图步骤你就可以生成2个包名不同的APP了
但是根据需求我们还需要查找出有关现有app的图片文字进行替换
以及有关推送分享登陆模块创建confige配置文件使租户可以使用自己的账户

然后通过读取项目配置做差异化

之后通过读取文件取得个性化定制
但是此方式图片处理不是很好如果图片过多较难处理
思路通过唐桥猿题库的博客

在Xcode的一个项目中，可以允许建立多个编译的target，每个target代表着最终编译出来的一个App文件，在每个target中，可以添加不同的编译源文件和资源文件。最终，通过我们在不同target之间，修改其 Copy Bundle Resources 和 Compile Sources 配置，使课程之间的差异性得到实现。我们具体的配置方案如下：

我们的每个课程的资源文件都具有相同的文件名，例如首页背景都叫 HomeBackgroundBg.png ，由于每个课程背景不一样，所以我们在工程中，每一个课程target下，通过修改Copy Bundle Resources，使其都配置有不同的（但是同名） HomeBackgroundBg.png 。这样的好处是，在代码逻辑层面，我们可以完全不用处理课程间资源文件的差异性问题。资源文件的差异性都是通过配置文件来保证的。

对于文案一类的差别，我们通过修改Compile Sources，使不同的课程有着不同的文案定义文件。通过这样，我们使不同课程有了不同的文案。另外包括后台网络接口的差异性问题，统计项的差异性问题，也都是这样处理的。

如此简易版的多target 相似项目也就又了一定的可行性
