Hey all. I'm still pretty new to iPhone development, and I'm having a bit of trouble figuring out how to change the title of my Navigation Bar. On another question on this site somebody recommended using :

I have a UINavigationController that contains 3 UIViewControllers on the stack.

I have a ViewBased App. I added a UITableView on one of the UIViewControllers. It shows the data and I implemented all the delegate methods etc. My problem is when I want to show the detailView it just doesn't happen. My code: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { DetailViewController *detailViewController =[[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; NSLog(@"DidSelectRowAtIndexPath"); // Pass the selected object to the new view controller. [self.navigationController pushViewController:detailViewController animated:YES]; [detailViewController release]; } I see that I need a navigationController but I don't have one and I was unsucessful trying to add one programatically. I don't have one in my appDelegate either, so my question is do I need to add one to show the detail view? If yes, please give me a code sample

I have a UIviewcontroller in a navigation based project, to which i am pushing some views as a result of some button action. When I first load this view, its size is showing (0,0,320,416) in the viewwillappear method. But, if you run it again, its size is showing (0,0,320,460) in the same viewwillappear method. My view is seems to be resizing when you load it again. Due to that I have so many problems in the pushed view. Can anybody help me please?

In my app, I have 5 navigation controllers. One of the navigation controllers displays 3 view controllers sharing the same data (from a Sqlite database). The only difference is that they present the data in a different way : ViewController 1 = recipes sorted by countries ViewController 2 = recipes sorted by vegetables ViewController 1 = recipes sorted by wines to drink with The Sqlite database is fed with a web-service. As new recipes may be added anytime, I need to refresh the database anytime the application becomes active. And as the application can become active on any of the view controller (depending on the one selected when the app went to background) I have to write the refresh code in the 3 view controller implementation files. I think this method sucks because the web-service is called when the user switch between the navigation controllers. This create frequent and useless traffic and database updates. I would prefer to do the job only one time per applicat
