Help With UINavigationController

[malidog96]

Hey Everyone
I'm developing an app and i need some help.

I have a login screen displayed over a UINavigation Controller and i want it to pushTo the next view controller that is under the login screen. the problem is, is that the view under the login view is controlled by another view controller and so therefore self.navigationController pushViewController:newScreen dosent work.

What i have is:
Login.m

...

-(IBAction) logIn:(id)sender {
			
			[self dismissModalViewControllerAnimated:YES];
			
			//I am Currentaly in Home view and need to push to First view

I have tried doing

[home.navigationController pushViewController:firstView animated:YES]

but that dosent work

Please Help

you say "the view under the login", there is a view under another? if so, just hide (or removeFromSuperview) navigationController.

[malidog96]

Yeah, the home view is under the login page(which was called by presentModalViewController)

I want the home view to push to the Next view when i click the login button on the login page.

You can look at the diagram, the login screen has a button and the button causes the home view to push to the Next view before the login dismissModalView happens.

debug that line, because it is the right way to do it.

[home.navigationController pushViewController:firstView animated:YES]

home.navigationController is your navigation controller? firstView is correctly initialized

[malidog96]

yes now ive initialized home by doing

@interface loginViewController{
homeViewController *home;
}

in the login.h file and then done a

-(IBAction)login{
home = [[homeViewController alloc] init];
[home.navigationController pushViewController:firstView animated:YES];
}

in the login.m file

did i implement home correctly???

P.S. - I don't really know how to use the gdb debugger. How would i debug a line??

Best Regards,

hey dany88
i made a test file.

i haven't added any text but you can figure it out.

button to access the login view is at the right hand side of the navigation bar

the login screen has a button that dismisses the view and attempts to push the view controller. you can mess around with the test project to try to get it to work for you.

it is attached at the bottom.

[dany_dev]

for "debug" i mean to add some breakpoint to see what happen.

However i downloaded the sample, the problem is that you are doing

	RootViewController *home = [[RootViewController alloc] init];
	FirstView *firstView = [[FirstView alloc] initWithNibName:@"FirstView" bundle:nil];
	[home.navigationController pushViewController:firstView animated:YES];

in other words, you are allocing a new RootViewController and you say "in navigationController of this NEW viewcontroller (and not the viewcontroller that i have already allocated and added to my view), please push FirstView"

what you need is:

testAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
	
	FirstView *firstView = [[FirstView alloc] initWithNibName:@"FirstView" bundle:nil];
	[appDelegate.navigationController pushViewController:firstView animated:YES];

In this manner, you are accessing at your appDelegate with a singleton method, and then you push on his navigationcontroller your view

ps: don't miss the [firstView release]; for don't leak.
