前言
由于Xcode的习惯，很多OC代码中.h文件引用都是只写文件的,因为Xcode会自动查找该文件的真实位置再传递给编译器编译,但这种做法有个限制,就是必须把.h文件引用到项目中,不然会找到,笔者的问题也就源于此,出于个人习惯,我不喜欢把不需要修改的文件引用到项目中,特别是编译好的库,一般情况下都是只引用.a文件,然后包含一个头文件全部搞掂,即方便后期维护第三方库,也方便文件管理,鉴于手动修改的文件实在太多了,这种没含量的浪费时间行为,还是交给CPU吧,于是便有了此文.
(特别说明,此工具的作用是把#import "header.h",扩展为#import "../../include/header.h"的形式,如果没这个需求就不用向下看了)
正文
假设源引用是#import "header.h",然后该文件放在上两层的include目录中(也就是../../include/header.h),先整理一下思路,要找到.h文件,第一种是暴力法,枚举整个项目目录,把找到的文件填充进去,但感觉不是很好(感觉会有隐性BUG),第二种是先列举所有可用文件列表,再从列表中匹配,这种方法可自定义程度高,本文采用此法.
进行项目目录,用命令行find . -name "*.h">~/Desktop/1.txt && find . -name "*.m">>~/Desktop/1.txt把所有可能的文件生成列表(若有其它格式,继续添加,如.mm),打开.txt把./替换为完整的路径,然后把文本拆解为单行的数组,也就是完整的文件路径,对每个文件进行读取,查找引用,替换引用,重新保存,过程如下:
- 1.查找源文件目录中是否存在引用文件,若有,则优先使用.
- 2.查找子目录中是否存在引用文件,若有,则优先使用.
- 3.如源文件目录和子目录都找不到,则搜索切换到父目录重新执行,若枚举完所有路径都找不到,那就写入出错日志(代码中未实现,可自行添加).
代码如下,有什么疑问欢迎和我交流.
