Qt - 访问束路径 [英] Qt - accessing the bundle path
本文介绍了Qt - 访问束路径的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
Qt文档 Mac差异页面提供了访问应用程序包路径的以下代码：
The Qt documentation "Mac Differences" page provides the following code for accessing an application's bundle path:
CFURLRef appUrlRef = CFBundleCopyBundleURL(CFBundleGetMainBundle());
CFStringRef macPath = CFURLCopyFileSystemPath(appUrlRef, kCFURLPOSIXPathStyle);
const char *pathPtr = CFStringGetCStringPtr(macPath,CFStringGetSystemEncoding());
qDebug("Path = %s", pathPtr);
CFRelease(appUrlRef);
CFRelease(macPath);
但是，对于更简单的东西来说有什么优点：
However, what is the advantage of that over something simpler, like the following:
QDir dir = QDir(QCoreApplication::applicationDirPath());
dir.cdUp();
dir.cdUp();
return dir;
推荐答案
Qt 5和OS X 10.9更大的是：
The modern way with Qt 5 and OS X 10.9 or greater is:
CFURLRef url = (CFURLRef)CFAutorelease((CFURLRef)CFBundleCopyBundleURL(CFBundleGetMainBundle()));
QString path = QUrl::fromCFURL(url).path();
