【Unity项目实战】本地存储工具类LocalSave分享

如果想要查找存储值的位置的话：

1. Mac OS
   在Mac OS X上PlayerPrefs是存储在~/Library/Preferences文件夹，名为unity.[company name].[product name].plist，其中company name和product name名是在Project Setting中设置，.plist文件可用于编辑器和桌面平台运行。 (打开Find，按住Option键，点击“前往 →“资源库”，就可以找到Preferences文件夹。)

2. Windows
   在Windows平台下，PlayerPrefs被存储在注册表的 HKEY_CURRENT_USER\Software[company name][product name]键下（打开“运行”输入regedit打开注册表），其中company name和product name名是在Project Setting中设置。

3. 例如
   [HKEY_CURRENT_USER\SOFTWARE*1*2]
   *1对应PlayerSettings的Company Name
   *2对应Product Name
