我有一个基于Qt（4.8.5）的应用程序在OS X 10.9上运行。该应用程序使用QSettings类指定应用程序名称和公司。 Plist文件由QSetttings在以下位置创建：
~/Library/Preferences/com.company_name.app_name.plist
The app works pretty fine in terms of saving/restoring preferences. Then I quit the app, delete *.plist file, run the app again and voila - it restored its preferences! Based on what what file? Hot to delete it?

In 10.9 (and higher) .plist files are being cached. So once you have deleted a .plist file, the cache must be refreshed. Either log out or execute the following command in Terminal:
在10.9（及更高版本）中，正在缓存.plist文件。因此，一旦删除了.plist文件，就必须刷新缓存。在终端中注销或执行以下命令：
killall -u yourusername cfprefsd
