iPhone SQLite页面缓存不断增长

I use sqlite数据库用于存储。还有许多数据库事务。我的问题是 sqlite 页面缓存的内存使用量快速增长。在instruments我可以找到这条线

Graph   Category                 Live Bytes   # Living # Transient  Overall Bytes   
0       VM: SQLite page cache    12.12 MB     97       1434         191.38 MB   

里面有 97 个以下文件

任何导致此问题的原因或如何删除这些文件的想法将不胜感激。 谢谢你！

找到答案了，这只是一个sqlite选择我错误输入的方法sqlite3_close(mySqliteDB);代替sqlite3_finalize(statement);
