iphone - 如何在尝试实现我的DBAccess类时修复sqlite3错误

我正在尝试使用sqlite3函数调用数据库的数据库访问类，但是却遇到了所有这些错误，如果有人之前经历过此类错误，或者是否有任何想法，我就很痛苦为什么它们会发生。

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
  "_sqlite3_step", referenced from:
      -[DBAccess getAllMakes] in DBAccess.o
  "_sqlite3_column_text", referenced from:
      -[DBAccess getAllMakes] in DBAccess.o
  "_sqlite3_prepare_v2", referenced from:
      -[DBAccess getAllMakes] in DBAccess.o
  "_sqlite3_open", referenced from:
      -[DBAccess initalizeDatabase] in DBAccess.o
  "_sqlite3_close", referenced from:
      -[DBAccess initalizeDatabase] in DBAccess.o
      -[DBAccess closeDatabase] in DBAccess.o
ld: symbol(s) not found
