Mac 枚举所有进程窗口并截图

清除app的所有权限
tccutil reset All com.xxx.xxx
mac 10.15 调试程序每次启动都需要重新授权。

// 1. 先获取window列表 CGWindowListOption 可以换成自己需要的  windowid传空可以获取所有窗口
    CFArrayRef windowsRef = CGWindowListCreate(kCGWindowListOptionOnScreenOnly | kCGWindowListExcludeDesktopElements, kCGNullWindowID);
    CFArrayRef windowInfoRef = CGWindowListCreateDescriptionFromArray(windowsRef);
// 2. 遍历窗口，对窗口截图
    int index = 0;
    int count = CFArrayGetCount(windowsRef);
    for (int i = 0; i < count; i ++) {
        // 3. 获取窗口ID
        CGWindowID wid = (CGWindowID)CFArrayGetValueAtIndex(windowsRef, i);
        // 4. 获取窗口信息
        NSDictionary *dict = CFArrayGetValueAtIndex(windowInfoRef, i);
        NSDictionary *value = dict[(NSString *)kCGWindowBounds];
        NSLog(@"%@", dict);
        NSLog(@"%@---%@---%@---%@", value[@"X"], value[@"Y"], value[@"Width"], value[@"Height"]);
        NSString *x = value[@"X"];
        NSString *y = value[@"Y"];
        NSString *width = value[@"Width"];
        NSString *height = value[@"Height"];
        NSNumber *number = dict[(NSString *)kCGWindowLayer];
        // 5. 过滤窗口，好像 kCGWindowLayer == 0的是应用程序窗口，其他类型的是menubar还有其他一些东西，暂时搞不清楚
        if (number.intValue == 0) {
            // 6. 通过windowID 和rect获取窗口截图
            NSRect rect = NSMakeRect(x.intValue, y.intValue, width.intValue, height.intValue);
            CGImageRef imgRef = CGWindowListCreateImage(rect, kCGWindowListOptionIncludingWindow, wid, kCGWindowImageDefault);
            NSImage *img = [[NSImage alloc] initWithCGImage:imgRef size:CGSizeZero];
            NSImageView *imageView = [[NSImageView alloc] initWithFrame:NSMakeRect(0, 100 * index, 100, 100)];
            [self.view addSubview:imageView];
            imageView.image = img;
            index += 1;
        }
        
    }
