Navigating my nib/xib files

[learningCentres]

Afternoon All,

Can anyone see any errors with the code below, it succeeds ok but doesn't show the second nib file, when I click on the button it does nothing...

- (IBAction) EnglishOneButtonPressedid)sender {
EnglishOneViewController *englishOneViewController = [[EnglishOneViewController alloc] initWithNibName:@"EnglishOneViewController" bundle:nil];
[[self navigationController] pushViewController:englishOneViewController animated:YES];
[englishOneViewController release];
}

(apart from the sad face pmsl)

[learningCentres]

Now I've also tried

- (IBAction)EnglishOneButtonPressedid)sender
{
EnglishOneViewController *englishOneViewController = [[EnglishOneViewController alloc] initWithNibName:@"EnglishOneViewController" bundle:nil];
[self .navigationController pushViewController:englishOneViewController animated:YES];
[englishOneViewController release];
}

but this doesn't work either any idea's?

Are you sure the Nib is called "EnglishOneViewController"?

Thanks for your reply, Yeah it is definitely named like that Would I need to add anything to EnglishOneViewController.h or .m

Here is the complete RootViewControllers.m

#import "LearningCentresViewController.h"
#import "EnglishOneViewController.h"

@implementation LearningCentresViewController

- (IBAction)EnglishOneButtonPressed:(id)sender 
{
    EnglishOneViewController *englishOneViewController = [[EnglishOneViewController alloc] initWithNibName:@"EnglishOneViewController" bundle:nil];
    [self .navigationController pushViewController:englishOneViewController animated:YES];
    [englishOneViewController release];
}

- (IBAction)MathsOneButtonPressed:(id)sender 
{
    MathsOneViewController *mathsOneViewController = [[MathsOneViewController alloc] initWithNibName:@"EnglishOneViewController" bundle:nil];
    [self .navigationController pushViewController:mathsOneViewController animated:YES];
    [mathsOneViewController release];
}





/*
// The designated initializer. Override to perform setup that is required before the view is loaded.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
        // Custom initialization
    }
    return self;
}
*/

/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
}
*/


/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
}
*/


/*
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
*/

- (void)didReceiveMemoryWarning {
	// Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];
	
	// Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
	// Release any retained subviews of the main view.
	// e.g. self.myOutlet = nil;
}


- (void)dealloc {
	
    [super dealloc];
}

I am aiming to have one main screen which has two buttons one leading to EnglishOneViewController.xib and one going to MathsViewController.xib

In your maths code you need to change the Nib name, but other than that it should be working.

Xcode isn't giving you any warnings or errors?

Oh yeah, I've done that now... no warnings, no errors nothing? just that nothing happens

I have attached the project because there must be something I'm missing I have re-written the code twice and still can't get it to work!!! ARGHHHH

[harrytheshark]

I see the problem now, you don't have a navigation controller to do the pushing.

Ok I see... What file would I need to code it in? RootViewController?

[harrytheshark]

Yeah, the root view controller

Would you mind giving me a hint on what code I need? My head hurts from searching...Do I just need to declare the class?

[harrytheshark]

Try creating a new navigation based project, and see what's in that and how it works.

Think I've made it worse lol....

Doesn't want to load at all now...

my h file is

@interface LearningCentresViewController : UIViewController {
	
	UIViewController *navigationController;
	
}

@property (nonatomic, retain) UINavigationController *navigationController;

- (IBAction) EnglishOneButtonPressed:(id)sender;
- (IBAction) MathsOneButtonPressed:(id)sender;

@end

and m is

I thought I could make UINavigationController into a pointer type of *navigationController - but it now errors saying 'type of property "navigationController" does not match type of iVar "navigationController"???????

[learningCentres]

Can anyone recommend a good tutorial for switching NIB files?
