TabView Help: clicking on a button and loading xib hides tab

[grem28]

Hey all, i'm really new to all this iphone dev and i'm just trying to get some stuff working. I have a tabView controller that has 5 tabs. Each tab loads a xib file. In the first xib file i have 4 buttons. When i click on one of the buttons i am making it load a new xib. the problem is that by doing this, it loads the xib, but it seems to load it over the tabView.... another words, the tab bar disappears. How do i fix this. Thanks all!

Do you really expect an answer without showing any code?

welcome.xib is already loaded as the first tab.. here's the code.

Welcome.h

#import <UIKit/UIKit.h>
@class Page1;


@interface Welcome : UIViewController {

	IBOutlet UIButton *allBut;
	Page1 *pg1;
	
}

@property (nonatomic, retain) IBOutlet UIButton *allBut;
@property (nonatomic, retain) Page1 *pg1;

- (IBAction) getButView: (id) sender ;

@end

Welcome.m

#import "Welcome.h"
#import "Page1.h"


@implementation Welcome
@synthesize allBut, pg1;

- (IBAction) getButView: (UIButton *) sender {
	
	switch (sender.tag) {
		case 0:
			//Page1 *svc = [[Page1 alloc] initWithNibName: @"Page1" bundle: nil];
			//pg1.delegate = self;
			
			pg1 = [[Page1 alloc] initWithNibName:@"Page1" bundle:nil];
			
			[self presentModalViewController: pg1 animated: YES];
			[pg1 release];
			break;
			
		case 1:
			NSLog(@"But 2");
			break;
			
		case 2:
			NSLog(@"But 3");
			break;
			
		case 3:
			NSLog(@"But 4");
			break;
			
		default:
			NSLog(@"HELLO2");
			break;
	}
}

Page1.xib is just a page with text in it.

presentModalViewController will take over the whole screen. If you still want to see the tab bar, then you should do something else. Perhaps use a navigation controller to push the new view controller.

here's the layout i'm trying to do:




click on the about, it takes u to the about.xib with the tabs on the bottom.

[BrianSlick]

That's fine. Use a navigation controller.

does the navigation controller go on the welcome.xib or on the about.xib?

[BrianSlick]

Neither. It will be the first view controller in your Welcome tab. You will specify which view controller should appear first in the navigation controller.

sorry dude, i'm a noob. you kinda lost me there. I used the TabBar Application template.

The first tab is set to welcome.xib. Where do i stick the navigation controller to? Won't sticking the navigation controller also place a tabbar on top of the initial design... i.e.



?

The navigation bar can be turned off.

Right now you have:

Tab bar controller
...view controller
...view controller
...view controller
...view controller
...view controller

What you need to have:

Tab bar controller
...Navigation controller
......view controller
...view controller
...view controller
...view controller
...view controller

so how do i go abouts doing that? In IB, i select the first tab and (what i did before) then select the welcome. how do you select a navigation conroller?

[BrianSlick]

Drag a navigation controller directly to the tab bar.

Hold on... i just realized something. How will it be with the tab buttons. do each one load a navcontroll or only the one i want.

TabController
tab1
(NavC)
Welcome
About
Videos
etc

tab 2
Events

tab 3
Donate
tab 4
(NavC)
FindUs (map)
Details page (annotation call out)

that's correct right?

[BrianSlick]

Yes.

Another question for you... how do i make it so the fourth button on my welcome screen says something like contact us. when the user clicks, it brings up a menu from the bottom that will have 3 options: call us (click it and it dials), email (click and email opens up), and cancel. Here's a screenshot from an app i have that has that menu i'm referring to.



Thanks for everything... really, you are awesome!

See the UINavigationController documentation.

okay, i'm real close now. I got the navigation working. i click on one of the four buttons and it slides to my "Page1.xib" (about us). Now, on the Welcome.xib, i have the navigation controller hidden. When i click on the About button and load the Page1.xib, how do i get the controller to show up with the back button? I tried adding a navigation controller in IB but that doesn't seem to connect to the original nav controller.

[BrianSlick]

The navigation controller is still there. The bar is simply hidden. Show it. Read the documentation for that class.

Thanks for your help brian. I really appreciate it! Sorry that i still don't get it. I looked at the documentation and here's what I got...

- (void)viewDidLoad {
    [super viewDidLoad];
	
	self.title = @"About Us";
	[self.navigationController popViewControllerAnimated:YES];
}

I placed that in the page (About Us) that is being loaded and my navigation bar is still missing. What am i doing wrong?

[BrianSlick]

You really didn't find any methods related to the navigation bar? Really?

ok... i found what you were talking about... i tried to implement it but i'm doing something wrong...

- (void)viewDidLoad {
[super viewDidLoad];

self.title = @"About Us";
- (void)setNavigationBarHidden:NO animated:YES animated ;

}

This doesn't work. how do i get this to work?

[BrianSlick]

Oh boy. You need to get yourself an Objective-C book, quickly.

[[self navigationController] setNavigationBarHidden:NO animated:YES];
