Question

我想在iOS上安装OpenCV，但不是所有模块，只是少数。

我怎样才能做到这一点？是否有一个参数我可以传递给build_framework.py脚本，允许我这样做？

我关注了OpenCV tutorial，但对此没有任何说明。

从v2.4.6开始，OpenCV有一个自定义的python脚本来简化工作（plateforms＆gt; ios＆gt; build_framework.py）

您只需在cmake行添加标志即可进行自定义编译。

例如：我只需要lib imgproc并将所有标题包含在存档中，我的cmake现在重新解析这个：

cmakeargs = ("-GXcode " +
            "-D BUILD_SHARED_LIBS=OFF "+
            "-D BUILD_opencv_core=ON "+
            "-D BUILD_opencv_imgproc=ON "+
            "-D BUILD_opencv_world=ON "+
            "-D BUILD_opencv_gpu=OFF "+
            "-D BUILD_opencv_calib3d=OFF "+
            "-D BUILD_opencv_contrib=OFF "+
            "-D BUILD_opencv_features2D=OFF "+
            "-D BUILD_opencv_flann=OFF "+
            "-D BUILD_opencv_highgui=OFF "+
            "-D BUILD_opencv_legacy=OFF "+
            "-D BUILD_opencv_ml=OFF "+
            "-D BUILD_opencv_nonfree=OFF "+
            "-D BUILD_opencv_objdetect=OFF "+
            "-D BUILD_opencv_photo=OFF "+
            "-D BUILD_opencv_stitching=OFF "+
            "-D BUILD_opencv_video=OFF "+
            "-D BUILD_opencv_videostab=OFF "+
            "-DCMAKE_BUILD_TYPE=Release " +
            "-DCMAKE_TOOLCHAIN_FILE=%s/platforms/ios/cmake/Toolchains/Toolchain-%s_Xcode.cmake " +
            "-DCMAKE_INSTALL_PREFIX=install") % (srcroot, target)

不要忘记添加核心和世界库，因为它们是强制性的。执行python脚本＆gt; profite。

之后，手动将lib添加到项目中，并删除标题中留下的讨厌的导入标题＆gt; opencv.hpp，你应该好好去！
