this seems to work fine in the simulator but on the device the files are not being written.
这似乎在模拟器中工作正常，但在设备上没有写入文件。
here's the code.
这是代码。
-(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
iPhone上没有主目录：D
You should use this instead:
你应该使用它：
NSString *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
This will give you the basic documents directory, append strings to it then.
这将为您提供基本文档目录，然后为其附加字符串。
