HOW TO BUILD A OPENCV PROJECT BY XCODE ON MACBOOK

step1:

MacOS Xcode新建一个opencv工程新建一个xcode工程- >选择command line tool ->命名你的工程并选择语言为c++

step2

点击工程->Building Settings->搜索Searching Paths
MacOS Xcode新建一个opencv工程
在 Header Searching Path 后填写：/usr/local/include
在 Library Searching Path 后填写：/usr/local/lib /usr/local/Cellar/opencv/3.4.3/lib#

step3

配置工作目录（方便使用相对路径）：
Product -> Scheme -> Edit Scheme -> Options -> Working Directory -> Use custom working directory MacOS Xcode新建一个opencv工程

step4

MacOS Xcode新建一个opencv工程
在工程目录下新建一个group->点击桌面shift+command+g进入文件夹全选其中的.dylib文件拖入新建的group

step5

若工程涉及调用mac自带的摄像头请进行如下操作（因为新版本macos的隐私权限问题）

按照里面的方法制作一个info.plist开启摄像头权限
MacOS Xcode新建一个opencv工程
进入/用户/xueruixiang/Library/Developer/Xcode/DerivedData/工程名/build/Products/Debug,将做好的info.plist放进去
就可以访问mac的摄像头啦！！！
附上测试程序

#include
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

IplImage* doCanny(IplImage* image_input,
double lowThresh,
double highThresh,
double aperture)
{
if(image_input->nChannels != 1)
return (0);

IplImage* image_output = cvCreateImage(cvGetSize(image_input),
                                       image_input->depth,
                                       image_input->nChannels);

cvCanny(image_input,image_output,lowThresh,highThresh,aperture);

return(image_output);

}

int main(int argc, char* argv[])

CvCapture* capture = cvCreateCameraCapture(CV_CAP_ANY);

assert(capture != NULL);

IplImage *frame = 0;

IplImage *frame_edge = cvCreateImage(cvGetSize(frame),
                                     IPL_DEPTH_8U,
                                     1);
while(1)

    frame = cvQueryFrame(capture);
    if(!frame) break;
    
    cvConvertImage(frame,frame_edge,0);
    frame = cvCloneImage(frame_edge);
    
    frame_edge = doCanny(frame_edge,70,90,3);
    
    cvShowImage("Camera",frame_edge);
    char c = cvWaitKey(15);
    if(c == 27)  break;
}

cvReleaseCapture(&capture);
cvReleaseImage( &frame_edge );
cvReleaseImage( &frame);


return (int)0;
