What you are observing is "expected": as of today, the QCView does not
support being used in a NSView tree backed by CALayers

Hi Apple Gurus.
I came across a very strange problem when create my GUI in interface
builder.
When create a new application, I open the .nib file, drag a QCView
onto it.
Then I specify the load file to let the QCView to play it. Building
the application and run, everything works perfectly.
Now, I want to try an experiment: I open the inspector window of
QCView and go to the Core animation part, there is two options of
view: ContentView and View. I thought one is for the root window
which the QCView hosts, the other is for the QCView itself.
I checked both of them, and went to the background filter part. Then
I added a core image filter: bloom to the window ground. As you
know, the QCView in the Nib window is usually black. After I added
the bloom filter, the edge of the QCView shows bloom effect. This
proved that the Bloom Core Image filter had been added to the QCView
in the interface builder at least.
However, when I rebuilded the Application to run it, the QCView
disappeared. I can't see the Quartz Composer Composition animation.
After I unchecked the two options mentioned above, the QCView
appeared again. What's more, as long as any one of options is
checked, the QCView doesn't work. So I guessed whether the QCView
doesn't support the core animation function to add with it?
Thank you for any reply. Good Luck.
