iphone - 如何将架构armv7、armv7s添加到{name}.framework？

Question

我正在使用libmusicxml2.framework在我的 iOS 应用程序中。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，我收到以下错误:

    Undefined symbols for architecture armv7:
  "vtable for MusicXML2::xmlreader", referenced from:
      MusicXML2::xmlreader::~xmlreader() in TransposerLibXML.o
      MusicXML2::xmlreader::xmlreader() in TransposerLibXML.o
  NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

如何添加对 libmusicxml2.framework 的 armv7 支持？请帮忙..

您需要根据 iOS SDK 构建框架。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创建 iOS 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。也许您可以向该框架的作者寻求帮助。
