ios打framework包：Undefined symbols for architecture arm64:

首页查看framework支持的CPU类型：

lipo -info MixedDevelopmentCameraAndPhotoAlbum.framework/MixedDevelopmentCameraAndPhotoAlbum

Architectures in the fat file: MixedDevelopmentCameraAndPhotoAlbum.framework/MixedDevelopmentCameraAndPhotoAlbum are: armv7 armv7s i386 x86_64 arm64 

如果都支持，查看加入framework的项目中，是否引用framework包（不单单是拷贝过去，xcode必须引用）
