我在我的 iOS 应用程序中使用libmusicxml2.framework 。她是为 Mac OSX 构建的，当我在模拟器上运行它时一切正常。但是当我在设备上运行时，出现以下错误：

    Undefined symbols for architecture armv7:

  NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

如何为 libmusicxml2.framework 添加 armv7 支持？请帮忙..

您将需要再次构建您的框架 iOS SDK。它具有不同的项目文件结构，并且 SDK 支持完全不同的功能集：OSX 中支持的许多方法和类在 iOS 中不支持。您可以尝试从头开始为 iOS 创建项目文件，但这将是一项具有挑战性的任务，并且由于 SDK 不兼容，无法保证成功。也许您可以向框架的作者寻求帮助。
