OK, I took a step back today and reconvened the knowledge you guys
have shared, reread the Hillegass chapter on GC (what a great
book!!), and reviewed the approaches I had taken. One thing that
jumped out at me was that I had not revisited the flags:
_SM2DGraphView_Private =
NSAllocateCollectable(sizeof(SM2DPrivateData), NSScannedOption|
NSCollectorDisabledOption);
with the __strong declaration on the private data object. If I use
both flags as shown above (which is what was originally suggested by
Greg Parker AND the __strong declaration on
#define myPrivateData ((SM2DPrivateData __strong *)
_SM2DGraphView_Private)
the framework compiles, my project compiles with it and miracle of
miracles it appears to run fully. Obviously I need to put this
through its paces but this is the only time I have had a successful
run of this inclusive project with GC on. Thanks to everybody who
added a little bit, each piece has helped me to understand the whole
better even if the project eventually fails.
Can anybody see obvious problems in what I did above?
Yes. __strong should be part of the ivar declaration, not the #define.
