Say I have an NSValue object. How can I save this to disk and retrieve it later?

NSValues can’t be saved in aplist, which is whatwriteToFiledoes. You can use archiving instead:Save:
[NSKeyedArchiver archiveRootObject: myNSValue toFile:@"myPath"];Load:
NSValue *myNSValue = [NSKeyedUnarchiver unarchiveObjectWithFile:@"myPath"];
