Hi Eric,
I can confirm the image is not released, even by adding
HIImageViewSetImage(myView, NULL) like this
HIImageViewSetImage(myView, myImage1); // First image retained by the
view
CGImageRelease(myImage1);
// Now I need to replace the first image of the image view by another
image
HIImageViewSetImage(myView, NULL);
HIImageViewSetImage(myView, myImage2); // Second image retained by
the view
CGImageRelease(myImage2);
If you have any workaround I'm all ears!
Cheers,
Thimeau

When calling HIImageViewSetImage() the image is retained by the

before another image is set by another call to HIImageViewSetImage().
Example:
HIImageViewSetImage(myView, myImage1); // First image retained by
the view
CGImageRelease(myImage1);
// Now I need to replace the first image of the image view by
another image
HIImageViewSetImage(myView, myImage2); // Second image retained by
the view
CGImageRelease(myImage2);
When doing this it appears that when setting the second image,
HIImageViewSetImage() doesn't release the first image creating a
leak! Is there a way to do this properly?
I looked at the code and it looks to me that the
HIImageViewSetImage _should_ release the image already associated
with the image view. I haven’t written a test app to confirm this,
however.
If you can reproduce a problem with the image not being released,
please file a bug with a test app that shows the problem, and I’ll
take a look. Perhaps there’s a code path that I’m not seeing. I
might be able to suggest a workaround if so.
