这是错误：'NSInternalInconsistencyException'，原因：'更新时出错。 '数据库被锁定'” ***在第一掷调用堆栈：（ \t 0的CoreFoundation 0x00f5b5a9 __exceptionPreprocess + 185 \t 1 libobjc.A.dylib 0x00d8a313 objc_exception_throw + 44 \t 2的CoreFoundation 0x00f13ef8 + [NSException提高：格式：参数：] + 136 –

在我看来你还没有正确关闭数据库（sqlite3_close（database））。

对于未来的项目看一看FMDatabase：在您关闭数据库properly.Try重装数据库和表

Offtopic这可能发生在你的实现看起来像上面。

FMDatabase is an Objective-C wrapper around SQLite
