推荐答案

LaunchServices is the OS X API that contains info about the user's preferred applications.

函数将返回您要查找的数据.这是其用法的简短示例:

The LSGetApplicationForURL() function will return the data you seek. Here's a short example of its use:

#include <CoreFoundation/CoreFoundation.h>
#include <ApplicationServices/ApplicationServices.h>

int main(int argc, char *argv[])
{
  CFURLRef mailURL = CFURLCreateWithString(kCFAllocatorDefault, CFSTR("mailto://"), NULL);
  CFURLRef mailAppURL = NULL;
  OSStatus ret = 0;
  if((ret = LSGetApplicationForURL(mailURL, kLSRolesAll, NULL, &mailAppURL)) == 0)
  {
    CFStringRef path = CFURLCopyFileSystemPath(mailAppURL, kCFURLPOSIXPathStyle);
    CFShow(path);

    CFRelease(path);
    CFRelease(mailAppURL);
  }
  else
  {
    fprintf(stderr, "LaunchServices error %d\n", ret);
  }

  CFRelease(mailURL);
  return ret;
}

在我的系统上，显示/Applications/Mail.app.如果您需要有关退回商品的更多信息，可以使用

On my system, that prints /Applications/Mail.app. If you want more info about the returned item, you can use the LSCopyItemInfoForURL() function on mailAppURL.
