自用筆記，口胡莫怪
最近鼓搗用Unity開發IOS app，對每次生成Project都要在Xcode下手動添加Framework文件甚煩，查了下，可以用Postprocessbuildplayer解決
Postprocessbuildplayer（無後綴名），放在工程文件下Assets/Editor下，Unity在編譯最後會自動執行這個腳本文件
以下以ARToolKit所需添加的Framework文件為例：（參看這裡）

說明：文件的ID和FILEREFID需要用Xcode先正確生成一次工程，之後找到工程文件夾下的 Unity-iPhone.xcodeproj，右鍵 Show Package Contents ，用 TextEdit 打開其下的 project.pbxproj ，尋找要添加的文件名即可
上面的程序就是通過腳本直接生成 project.pbxproj 以達成直接添加所需文件和庫的目的
蛇足提示：ID和FILEREFID長得像但其實不一樣。。。某人二逼兮兮一晚上都運行不對就是因為眼瞎了。。。
