The Search Result Should Display in the Drop down List, If i click those Search result It should Redirect to the NewsDetailsViewController. I do not know how to do this can any one help me out of this issue .
Here is my NewsViewController.m

Thanks In Advance.
As far as searching is concerned, You'll have to search your arrays in the NewsViewController, based on keywords that the user enters and if any results are returned, the perform a segue to your NewsDetailsViewController where those results will be displayed. For performing segue to the NewsDetailsViewController, you can use this method,
[self performSegueWithIdentifier:@"segueIdentifier" sender:nil];
Another suggestion is to use UITableViewController instead of Dropdown. The reason being that it is available in the SDK itself and you can show somewhat more data using TableView whereas Dropdown has to be made custom.
