If hide this code from JWNavigationController.m so searchDisplayController is working rootViewController.navigationController = self;

but new problem is UITableVIew didselectrowatindexpath is notworking .. what can i do?

It should be UINavigationController instead of UIViewController in JWNavigationController.h file. Reason is isNavigationBarHidden is present in Navigation Controller. Also, if you are using navigation controller, then reason for crash is that JWNavigationViewController you are using is getting removed from memory, i.e. maybe you are removing that object from memory or it is getting release automatically. Try to check above both reasons, some solution will help you get out of this. — P.J, Dec 24 '13 at 10:45

Your JWNavigationController does not inherit from UINavigationController. But, isNavigationBarHidden is a method implemented by UINavigationController.

Now look at the error (which uses the term 'selector', but that refers to the method): It basically says that the instance of your JWNavigationController does not implement isNavigationBarHidden, and this is the issue.

Could it be that you mistyped, and meant to write:

@interface JWNavigationController : UINavigationController <UINavigationBarDelegate>

isNavigationBarHidden: is a selector which is only available in classes that derive from UINavigationController. You have to modify this line:

@interface JWNavigationController : UIViewController

with this:

@interface JWNavigationController : UINavigationController

UINavigationController not work with SearchDisplay Controller
