Hello,
I am writing a Cocoa application for accessing a serial device. (IOKit) In
order to do this, you need to translate between CF and NS data types. (I
believe)
For instance:
CFMutableArrayRef devicePaths = CFArrayCreateMutable(NULL, 0, NULL);
GetSerialPortPaths(serialServices, devicePaths); // Fills in
CFMutableArray
serialPorts = (NSMutableArray *) devicePaths;
//CFRelease(devicePaths);
printf("Found %d serial ports\n", [serialPorts count]);
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?
TIA
Allen
