## 复制Target

A target specifies a product to build and contains the instructions for building the product from a set of files in a project or workspace. A target defines a single product; it organizes the inputs into the build system—the source files and instructions for processing those source files—required to build that product. Projects can contain one or more targets, each of which produces one product.

## 更名Target

plist文件则修改为productnameBeta-Info.plist，同时，我还将其移到与默认的Info.plist文件在同个目录下。不只是在同一个分组下，也是在同一个物理目录下。改完plist文件后，还需要修改productnameBeta的Target的Info.plist File设置，该属性设置了相应Target绑定的plist文件是哪个。该属性值本来为productname copy-Info.plist，现需要更改为productname/productnameBeta-Info.plist

## 判别Target

#ifdef BETA
// 测试版需要执行的代码
#else
// 默认生产版需要执行的代码
#endif
