MacOs sandbox, security scoped bookmarks

[Plamen Petkov]

Hi,

I struggle writing a code related to MacOs security scoped bookmarks (related to MacOs sandboxing, where to keep access to user selected files across App runs one have to facilitate Security Scoped Bookmarks). Anyone having an experience on that matter or point to some links with examples?

Env: Qt 5.10, MacOs High Sierra

Hi and welcome to devnet,

Try something like:

QUrl url("file:///Users/your_user/your_file.extension");
NSURL *nsUrl = url.toNSURL();
NSError *error = nil;
NSData *bookmark = [nsUrl bookmarkDataWithOptions:NSURLBookmarkCreationWithSecurityScope
                                                  includingResourceValuesForKeys:nil
                                                  relativeToURL:nil
                                                  error:&error];
qDebug() << "Error" << error;
qDebug() << QByteArray::fromNSData(bookmark);

Hope it helps

Is this code can compile in *.cpp ?
I want to add them into my code but occurs some error...

#if defined(Q_OS_MACOS)
QUrl url = QUrl::fromLocalFile(selectFolder);
qInfo() << "Get url: " << url;

NSURL *nsUrl = url.toNSURL();
NSError *error = nil; // Unknown type name 'NSError'
NSData *bookmark = [nsUrl bookmarkDataWithOptions:NSURLBookmarkCreationWithSecurityScope
                                                  includingResourceValuesForKeys:nil
                                                  relativeToURL:nil
                                                  error:&error];
// Expected ',' or ']' in lambda capture list
qDebug() << "Error" << error;
qDebug() << QByteArray::fromNSData(bookmark);

#endif

That's Objective C++.
The code need to be in a *.mm file.
