Colin,
Thanks for your reply.
While you are right considering the code I have posted here, the truth is that
in my actual code I have the setObject. But since I have more stuff going on I
didn’t want to flood the list with code:
void Settings::setSharedKey(QString key, QVariant value)
{
if (defaults==nil)
defaults = [[NSUserDefaults alloc]
initWithSuiteName:@“group.com.acme.app"];
[defaults setObject:[ISettingsManagerCocoaHelper variantToNSObject:value]
forKey:key.toNSString()];
[defaults synchronize];
}
I’m still struggling with this. I can’t have the settings saved. I’m tired to
googling and trying stuff.
Any ideas? Do you have anything similar?
Thanks!
Regards,
Nuno
