尝试使用 Qt 访问 Mac .app 包中资源文件夹的文件路径。这是我的代码：

CFURLRef appUrlRef;


appUrlRef = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("AFE-MP-512"),NULL,NULL);
CFStringRef filePathRef = CFURLCopyPath(appUrlRef);



qDebug() << filePathRef;

// Release references
CFRelease(filePathRef);
CFRelease(appUrlRef);

我唯一拥有的是表单上的一个按钮来运行代码。尝试编译时出现以下错误：

Undefined symbols for architecture x86_64:
  "_CFBundleCopyResourceURL", referenced from:
      MainWindow::on_pushButton_clicked() in mainwindow.o
  "_CFBundleGetMainBundle", referenced from:

Error while building/deploying project ProgramLaunch (kit: Desktop Qt 5.3 clang 64bit)

我在 mainwaindow.h 中有以下内容

#include <QtCore>
#include <CoreFoundation/CFURL.h>
#include <CoreFoundation/CFBundle.h>

有什么想法可能会出错吗？谢谢

您需要与 CoreFoundation 框架链接。您可以将以下内容添加到您的 qmake 项目中：

LIBS += "-framework CoreFoundation"
