从文档文件夹中删除Sqlite数据库

Question

We have an iOS application for the iphone that is having strange behavior. I store some data of the app in an SQLite Database file in the documents folder. Every once in a while i realize that when the application crashes the file on the disk gets deleted. And i can´t figure out why the app would do this...Any Ideas?!

Answer 1

Make sure that you're saving any documents for the application to the application's private folder in the documents. I use this:

[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainask, YES) lastObject];

Answer 2

找到了解决方案...如果我将数据库保存在Cache Directory中而不是Documents目录中，那么它将起作用... :)
