We're developing an OSX app that have to be supported by OSX 10.7 to 10.9. We're currently using QTKit and QTMovieView to show videos, but when trying to upload a new version recently we got this error message:
Deprecated API usage. Apple no longer accepts submissions of apps that use QuickTime APIs.
We have also tested to set the Base SDK to 10.8, but same result there.
And changing to AVKit and AVPlayerView does not work for version prior to 10.9.
So is there a way to use AVKit for versions prior to 10.9 or some way to publish an app with QTKit?
