Use code like this to identify NSString in your array:

    NSMutableArray *arr = [[NSMutableArray alloc] init];
    [arr addObject:@"Best"];
    [arr addObject:@"Good"];
    [arr addObject:[NSNumber  numberWithInt:3]];

    for(NSString *str in arr)
    {
        if(str && [str isKindOfClass:[NSString class]])
        {
            NSLog(@"String: %@\n",str);    
        }
    }
