For example, assume you have an archived dictionary that records the call letters and associated frequencies of radio stations. To remove an entry for a defunct station, you could write code similar to the following:
NSMutableDictionary *stations = nil;
stations = [[NSMutableDictionary alloc]
initWithContentsOfFile: pathToArchive];
[stations removeObjectForKey:@"KIKT"];
