Problems accessing a picture on the iOS 10.2.1 using Qt 5.8

philippeb8

So I am trying to access a file selected by the QML engine (so I know the file exists):

    QString path = "file:assets-library://asset/asset.PNG?id=FF324EBC-DC50-4F6A-8F72-E93CB26D91F5&ext=PNG";

    QFile file1(path);
    if (!file1.exists())
        qCritical() << "file1 not found";

    QFile file2(QUrl(path).path());
    if (!file2.exists())
        qCritical() << "file2 not found";

    QFile file3(QUrl(path).toLocalFile());
    if (!file3.exists())
        qCritical() << "file3 not found";

And I get the 3 error messages. It used to work before but I guess the upgrade of iOS to 10.2.1 messes things up.

Hi,

Are you sure your id parameter is correct ?

philippeb8

Yes because it is a picture I select from the V-Play's camera roll. I hard coded the filename for this example.

What's more funny is if I try to print recursively the contents of the root folder in C then I get the following listing (there is no such "asset" subfolder):

I mean what is this?

philippeb8

All I know so far is that the AssetLibrary.framework is deprecated and replaced by the Photos.framework. This is most likely what is going on here.

Ok today it works. I didn't do anything except rerunning "qmake". Sorry for the noise...!
