can't figure out why archiveRootObject is failing to write file

Question

this seems to work fine in the simulator but on the device the files are not being written.

here's the code.

-(void)saveOld{

NSArray *saveState = [NSArray arrayWithObjects:headArray,dropQArray,[NSNumber numberWithInt:dropLimit],[NSNumber numberWithInt:dropCount],[NSNumber numberWithInt:score],[NSNumber numberWithInt:level],[NSNumber numberWithInt:maxChain],nil];

NSMutableString *path = [[NSHomeDirectory() mutableCopy]autorelease];
[path appendString:@"/saveState"];

BOOL saved = [NSKeyedArchiver archiveRootObject:saveState toFile:path];
NSLog(@"did save state %d",saved);
path = [[NSHomeDirectory() mutableCopy]autorelease];
[path appendString:@"/isSaveState"];


saved = [NSKeyedArchiver archiveRootObject:[NSNumber numberWithBool:1] toFile:path];
NSLog(@"did save state %d",saved);
}

There is no home directory on the iPhone :D

You should use this instead:

NSString *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

This will give you the basic documents directory, append strings to it then.
