我看到一个较老的iOS项目，我有一段时间没有做任何事情，我需要更新扫描仪的SDK，所以它是64位的。我将扫描仪套件的文件(拖放)添加到项目中，但现在当我构建时，我得到了错误架构armv7的未定义符号
它指的是arm64，但我尝试了几件事，现在它指的是armv7(设置其他链接器标志和编辑基本构建设置)。
我的构建设置是:架构:标准Base SDK 8.4只构建活动架构:不有效架构:armv7 armv7s arm64
构建的输出是:

唯一的错误与SDK有关，但我确认我已经安装了64位版本。提前感谢
我不知道我怎么把这个问题贴了两次，但它在这里得到了回答(XCode -架构armv7 arm64的未定义符号)。简而言之，我没有在我的项目中链接AVFoundation。
