//Read TopScore.plist  File

-(void)readTopScorePlist

{

NSError *error;

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //1

NSString *documentsDirectory = [paths objectAtIndex:0]; //2

NSString *path = [documentsDirectory stringByAppendingPathComponent:@"TopScore.plist"]; //3

NSFileManager *fileManager = [NSFileManager defaultManager];

if (![fileManager fileExistsAtPath: path]) //4

{

NSString *bundle = [[NSBundle mainBundle] pathForResource:@"TopScore" ofType:@"plist"]; //5

[fileManager copyItemAtPath:bundle toPath: path error:&error]; //6

}

NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile:path];

self.MyTopScore = [[data valueForKey:@"TopScore"] intValue];

[data release];

}

//Write To TopScore.plist

-(void)writeToTopScorePlist

{

[fileManager copyItemAtPath:bundle toPath: path error:&error]; //6

}

NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile:path ];

    [data setObject:[NSString stringWithFormat:@"%i",self.MyTopScore] forKey:@"TopScore"];

    [data writeToFile:path atomically:YES];

    [data release] ;
