iOS / Xcode 4: View won't load

This is really frustrating as I've tinkered with previous versions of Xcode and have done this before but playing around with a new app now, it's not working for some reason.

I have the app open to a UITableView and want it to load to a detail UIView once I select a cell. However, when I choose a cell in the iPhone simulator, it just highlights the cell blue and doesn't load the view.

Here is the code I'm using the the RootViewController:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
WorkoutViewController *workoutViewController;
workoutViewController = [[WorkoutViewController alloc] initWithNibName:@"WorkoutViewController" bundle:nil];
workoutViewController.workoutName = [workouts objectAtIndex:indexPath.row];
[self.navigationController pushViewController:workoutViewController animated:YES];
[workoutViewController release];
workoutViewController = nil;

I have the view linked to the File Owner in the WorkoutViewController.xib file. When I put in a breakpoint at @implementation WorkoutViewController, it does get to that breakpoint but it goes to the @synthesize line and then jumps right back out to [self.navigationController ...etc]; and never returns back to the WorkoutViewController.m file.

Doh! Problem resolved. I had forgotten to actually put the RootViewController into a navigation controller on the MainWindow.xib. Appreciate the responses.

I would guess that you didn't set the ViewController to be the TableView's delegate. To check, open your ViewController xib-file and rightclick FilesOwner. Under Referencing Outlet you would usually have both delegate and data source" connected to your TableView. If that is not the case, drag New Referencing Outlet to your TableView.

If I'm wrong and they are all connected, you might want put a breakpoint at the beginning of your didSelectRowAtIndexPath method. Does the debugger stop there, once you select a row?

It might also be worth mentioning that a breakpoint at @implementation usually doesn't make much sense, you would rather want to place it in a method like init. Also, even though you are using Xcode 4 now, this is unlikely to be the cause of your problem, it looks more like an implementation issue.

Hope this helps, if you need further help just let me know!
