UISearchDisplayController : application is showing exception

Im trying to work with UISearchDisplay controller the application is launching correctly. When i start typing in the UISearchbarController its showing the following exception and exiting the application.

The exception is as follows: [BrowserViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x5b4ccc0 2010-08-13 11:59:58.469 MixedApplication[7297:207] *** Terminating app due to uncaught except开发者_JAVA百科ion 'NSInvalidArgumentException', reason: '-[BrowserViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x5b4ccc0'

Can you post your code for the tableView:numberOfRowsInSection?
