【问题描述】：

我使用sqlite 数据库进行存储。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迅速增长。在instruments 我可以找到这一行

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

在其中我有 97 个以下文件

任何想法是什么原因或如何删除这些文件将不胜感激。 谢谢！

【参考方案1】：

找到答案了，只是sqliteselect方法我误把sqlite3_close(mysqliteDB);换成了sqlite3_finalize(statement);
