iOS uinavigationcontroller problem

[sagarshivam]

Dear All

In my sample project for iPad, I am using uisplitviewcontroller and further , uinavigationcontroller in root view controller (left panel of split view pane) so that on tapping the disclosure button of main table, next view (uitableview) comes up.

Logic is simple that I should push the object of next view class to navigation controller. But I dont understand where I am lacking.

Navigation_TestAppDelegate.m

@synthesize window, splitViewController, rootViewController, detailViewController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    
    UINavigationController *rootNav = [[UINavigationController alloc] initWithRootViewController:rootViewController];
	splitViewController.viewControllers = [NSArray arrayWithObjects:rootNav,detailViewController,nil]; 
    splitViewController.delegate = detailViewController;
    [window addSubview:splitViewController.view];
    [window makeKeyAndVisible];
    [rootNav release];
    return YES;
}

RootViewController.m is:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"CellIdentifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
  
    cell.textLabel.text = [NSString stringWithFormat:@"Row %d", indexPath.row];
	cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
    return cell;
}

and didSelectRowAtIndexPath method (of RootViewController.m)is:

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    
	    _nav= [[nextview alloc] initWithStyle:UITableViewStylePlain];
           // _nav is object of class nextview (uitableviewcontroller type)
	    [self.navigationController pushViewController:_nav animated:YES];
}

I am unable to understand that on tapping cell of root view controller, why nextview is not visible.

um, and what is your question?

Sorry for incomplete query. I just updated my query and code

In the code you showed us, _nav isn't declared anywhere. I believe you want it to be a pointer to a UITableView... did you declare it as such in your header file, perchance? It's also possible that the _ character does something special that I'm simply not aware of.

Also, you have "nextview". Is that a custom class? You haven't shown us your .h and .m for it.

_nav is declared properly. And nextview class is a standard UItableviewcontroller type.

When I am using the same way of pushing the other uitableviewcontroller class object (in my case it is _nav) in root viewcontroller without using uisplitviewcontroller, everything works fine.

Any suggestions?

You should probably follow standard naming conventions and rename your nextview class using "camel-case" (i.e. something like NextTableViewController. It will make things less confusing to those trying to help (or those having to maintain your code in the future).
