Iphone 如何在尝试实现DBAccess类时修复sqlite3错误

我正在开发我的数据库访问类，它试图用sqlite3函数调用DB，但是我得到了所有这些错误，我只是想知道是否有人以前遇到过这些错误，或者他们是否知道为什么会发生这些错误

Undefined symbols:
  "_sqlite3_finalize", referenced from:
      -[DBAccess getAllMakes] in DBAccess.o
  "_sqlite3_errmsg", referenced from:
      -[DBAccess initalizeDatabase] in DBAccess.o
      -[DBAccess closeDatabase] in DBAccess.o

将framework libsqlite3.0.dylib添加到框架中的项目中

好的，因为我没有添加sqlite框架。。或者，我只是想知道我现在要添加哪个框架。。一旦我弄明白了，我会发布一个更新。所以我不得不添加libsqlite3.0.dylib框架，所有的错误都消失了：）这感觉真棒，哈哈。好吧，因为我还没有添加sqlite框架。。或者，我只是想知道我现在要添加哪个框架。。一旦我弄明白了，我会发布一个更新。所以我最后不得不添加libsqlite3.0.dylib框架，所有的错误都消失了：）这感觉真棒，哈哈。
