Answer 1

This one do the trick.But i don't know whether it is the efficient way of doing this.

 NSArray *arrData = [NSArray arrayWithObjects:
                    @"cloud,country,plant",
                    @"country,cloud,plant",
                    @"country,plant,cloud",
                    @"clouds,country,plant"
                    ,@"country,clouds,plant",
                    nil];

NSMutableArray *resArray = [[NSMutableArray alloc]init];
for(NSString *tempString in arrData)
{
    NSArray *cache = [tempString componentsSeparatedByString:@","];
    if([cache containsObject:@"cloud"])
      {
        [resArray addObject:tempString];
      }
}
