使用libsqlite3.dylib和FMDB Xcode 7 ios9的体系结构i386的未定义符号

Question

我正在使用Xcode 7和iOS 9创建一个简单的应用程序，它使用sqllite3保存数据并检索它。但是，在使用libsqlite3.dylib库和从github检索到的FMDB构建应用程序时，我收到以下错误消息。

我在搜索周围后自己发疯，但无法找到任何解决方案。请建议。提前谢谢。

Answer 1

检查是否在Build Phases的Link Binary with Libraries部分中添加了libsqlite3.dylib

Answer 2

看起来您的项目与libsqlite3无关。仔细检查它是否与它相关联，如果是，可以将其添加为链接器标记。
