Plist files not being read

Question

Hey there, my app has a search bar that searches a plist file. I've created the plist file but I keep getting this error:

[Session started at 2010-07-27 19:11:07 +0530.]
2010-07-27 19:11:12.550 InfoCarApp[2062:20b] *** -[NSCFDictionary allkeys]: unrecognized selector sent to instance 0x3d51440
2010-07-27 19:11:12.552 InfoCarApp[2062:20b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFDictionary allkeys]: unrecognized selector sent to instance 0x3d51440'

My app basically searches through the plist and it has to display the data in an tableView. Here's the code how I have declared the plist:

- (void)viewDidLoad {
    [super viewDidLoad];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"sortednames" ofType:@"plist"];
    NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
    //self.names = dict;
    self.allNames = dict;
    [dict release];

    //NSArray *array = [[names allKeys] sortedArrayUsingSelector:@selector(compare:)];
    //self.keys = array;
    [self resetSearch];
    search.autocapitalizationType = UITextAutocapitalizationTypeNone;
    search.autocorrectionType = UITextAutocorrectionTypeNo;
}

Please help. Thanks in advance.
