Thanks guys, its starting to become a bit clearer now. I'll use the
alloc / init / release route for now until I"ve read through the
memory management doc
Cheers,
Memo.

I'm just writing a Quartz Composer plugin using the QCPlugIn API
and ran
into a problem regarding this, my question isn't related to the
QCPlugIn API
so I'm posting here first.
At the start of the plugin (in enableExecution) I use the code:
- (void) loadCardXMLData {
NSString *dataPath = @"/data.plist";
cardsLoadedData = [NSDictionary dictionaryWithContentsOfFile:
dataPath];
// cardsLoadedData = [[NSDictionary alloc] initWithContentsOfFile:
dataPath];
if(cardsLoadedData) {
NSLog(@"*** SUCCESSFULLY LOADED %@", dataPath);
} else {
NSLog(@"*** COULD NOT LOAD %@", dataPath);
}
}
If I use the convenience route (with no release in
disableExecution) I get a
freeze (I need to force quit QC) as soon as I enable the plugin. If
I use
the alloc route (and release in disableExecution) everything works
fine. Is
this normal behaviour? or could it be QC related?
P.S. cardsLoadedData is a property of my QCPlugIn class, and I
don't use it
at all except at the end of execute I just send it out to QC
with self.outputXMLData = cardsLoadedData;
Cheers,
Memo.
You're assigning an autoreleased object to your cardsLoadedData ivar.
Next time the autorelease pool pops, your dictionary is going to get
released. Either retain the dictionary, or use alloc+init, or
(preferably) use self.cardsLoadedData= instead of just
cardsLoadedData=, which will assign via the property method, which
will retain for you (assuming you've set up the property correctly).
