Delete a view

[kharaku]

Hi All

I am working off a customized version of
iPhone – Core Data and UITableView. A drill-down application

I want to delete the 'province' drop down and go strait to city.

I don't have a third tier of navigation in my app.

Here's the code I THINK I need to modify

// Override to support row selection in the table view.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
	if(self.entityName == @"County" || self.entityName == @"Province")
	{
		
		// Get the object the user selected from the array
		NSManagedObject *selectedObject = [entityArray objectAtIndex:indexPath.row];
		
		// Create a new table view of this very same class.
		RootViewController *rootViewController = [[RootViewController alloc]
												  initWithStyle:UITableViewStylePlain];
		
		// Pass the managed object context
		rootViewController.managedObjectContext = self.managedObjectContext;
		NSPredicate *predicate = nil;

		
		if(self.entityName == @"County")
		{
			rootViewController.entityName = @"Province";
			
			// Create a query predicate to find all child objects of the selected object. 
			predicate = [NSPredicate predicateWithFormat:@"(ProvinceToCounty == %@)", selectedObject];
			
			
			
		} 
		else if(self.entityName == @"Province")
		{
			rootViewController.entityName = @"City";
			
			// Create a query predicate to find all child objects of the selected object.
			predicate = [NSPredicate predicateWithFormat:@"(CityToProvince == %@)", selectedObject];
		}
	
		[rootViewController setEntitySearchPredicate:predicate];

		//Push the new table view on the stack
		[self.navigationController pushViewController:rootViewController animated:YES];
		[rootViewController release];
	}
	
	if(self.entityName == @"City")
	{
		// Get the object the user selected from the array
		City *selectedCity = [entityArray objectAtIndex:indexPath.row];
		
		DetailsViewController *detailsView = [[DetailsViewController alloc] initWithNibName:@"DetailsViewController" bundle:[NSBundle mainBundle]];
		
		
		detailsView.title = selectedCity.Name;
		detailsView.inhabitants = selectedCity.Inhabitants;
		detailsView.description = selectedCity.Description;
		detailsView.phone = selectedCity.Phone;
		detailsView.email = selectedCity.Email;
		
		
		//Push the new table view on the stack
		[self.navigationController pushViewController:detailsView animated:YES];
		[detailsView release];
	}
}

I want to go strait from the 'country' view to the 'city' view with the detailsView controller.

How the heck do I do that?

Oh for heaven's sake! You study the code, figure out where the middle view controller gets invoked, and change the logic to go from the first to the third view controller.

I get really tired of these "I want to write an app that dances and sings, and causes my iPhone to levitate. It will be great. Can you post some example levitation code?" type posts. Roll up your sleeves and figure this stuff out yourself! Buy a book that teaches you iPhone programming and read it cover to cover, doing all the exercises. In short, put some work into it, before asking other people to do your work for you!

I agree with Duncan.

Also - self.entityName == @"County" is bad.

Always compare strings with NSString's isEqualToString:.

There is no 3rd view there is a root controller and a detail view controller.

Further the point of a forum is sharing information.

I changed that to if([self.entityName isEqualToString: @"County"])
