reload tableview from navigation controller

I am new to iPhone development.

I have a navigation controller which loads a tableview. The class identity of the tableview is a tableViewController class.

I want to know how to refresh the table view from the navigation controller.

I know within the tableViewController i can use the

[self.tableView reloadData];

Sorry if i am vague. Thanks in advance.

after feedback:

Here is the navigation controller

@interface slNavController : UINavigationController{

UIToolbar *toolbar;
slTableViewController *tableVC;

}
@property(nonatomic, retain) slTableViewController *tableVC;

where slTableViewController is the Delegate of the tableView that needs to be refreshed.

and where i needed to refresh the table i used

[tableVC.tableView reloadData];

Here is slTableViewController header

@interface slTableViewController : UITableViewController <UITableViewDelegate,UITableViewDataSource> {

IBOutlet UITableView *slTableView;
NSMutableArray *list;
TryAppDelegate *appDelegate;
//UIToolbar *toolbar;
IBOutlet UITextField *textField;

}

But 开发者_JAVA技巧still not able to refresh the tableview.

There must be some viewController which is the delegate of the tableView. Send reloadData to that controller, e.g.

[viewController.tableView reloadData];

If you know where in the stack the viewController is, you can access it through the navController. For instance, if it happens to be the rootViewController, then you can do

HomesViewController *homesController = [[[self navigationController] viewControllers] objectAtIndex:0];

If it is Navigation based application you want to reload the data of table view, You have to write in view will appear like this

[self.tableView reloadData];

Give your navigationController a pointer to the tableViewController.

In the .h file:

@property(nonatomic, retain) YourTableViewController *tableViewController;

Then when you want to reload data:

[tableViewController.tableView reloadData];
