Question

How do you access a file to use in unit tests? (Every time I have asked with more specific information I cannot get ANYONE to answer.)

Answer 1

What exactly are you trying to do?
If you are trying to dump a data file and re-read it:

// To Dump:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);   
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"/MyDataFile"];
[NSKeyedArchiver archiveRootObject:mediaManager toFile:filePath];

// To Re-Load:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"/MyDataFile"];

myReciever = [[NSKeyedUnarchiver unarchiveObjectWithFile:filePath] retain];
