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?
