The problem: I found that if you release the CFMutableArray, you
also loose
the NSMutableArray
Question:
1. Where can I get a better understanding of the data conversion
between
these different frameworks?
2. Ultimately the device path names will appear in a ComboBox. Was it
necessary to convert the CFMutableArray to a NSMutableArray for the
datasource function?
It's more convenient to do it this way... however, you were just
casting the
types, not converting them. You could do something like this:
serialPorts = [(NSArray*)devicePaths copy];
CFRelease(devicePaths);
Or you could just retain your serialPorts object:
serialPorts = (NSArray *)devicePaths;
[serialPorts retain];
CFRelease(devicePaths);
