我在构建我的应用程序时遇到了这个错误。谁能帮我解决这个问题？

我正在使用 swift 和 parse.com。非常感谢您的帮助！

由于我无法发布图片，所以我在下面发布了整个错误消息。

【问题讨论】：

显而易见的起点是：您是否尝试链接到 sqlite3 库？如果有，怎么做？
在 PFSQLiteDatabaseResult.o 中也有同样的错误

标签： ios swift parse-platform

【解决方案1】：

经过反复试验，答案是再次检查所有框架。似乎 parse.com 在这几个月内才进行了更新。

目前它需要 libsqlite3.dylib 作为它的库。

如果你发现类似的问题，首先在这里查看最新的需求： https://www.parse.com/apps/quickstart#parse_data/mobile/ios/native/existing

【讨论】：

以防万一 Gibran 的回答不清楚，解决方法是转到 Build Phases -> Link Binary with Library 部分并将 libsqlite3.dylib 添加到链接库列表中
请注意，现在我们有“.tbd”库。 stackoverflow.com/questions/31450690/…

【解决方案2】：

我也遇到了这种情况，@Gibran 的回答让我走上了正轨。我使用 Xcode 7 和 iOS 9 发现的一个区别是 libsqlite3.dylib 已替换为 libsqlite3.tbd

【解决方案3】：

我以前遇到过这个问题。只需从框架中导入libsqlite.dylib 和libz.dylib，您的错误就会消失。

【解决方案4】：

你可以在那里找到答案（您需要将框架添加到您的项目中）
