UITabBarContoller --> UISplitViewContoller - iphone

I want to show full screen view controller from UISplitViewController detail view controller. But I want UITabBar still to be visible. When I presentViewController it will hide my UITabBar. Can anyone suggest me the flow?

You don't have to nest your UIViewController in a UINavigationController.
Then instead of
[someViewController presentViewController: anotherViewController];
you have to call
[someNavigationController presentViewController:anotherViewController];
this will do the trick.
Note that it will add the anotherViewController at the top of the stack of viewControllers.
to remove it just call dismissViewController on the navigation controller!

popToRootViewControllerAnimated doesn't modify attached navigationItem

My UIViewController calls a function on my rootViewController which then called popToRootViewControllerAnimated to return the view to the rootController. This all works - great!
Unfortunately the UINavigationItem (toolbar at the top) seems to display a mashup of both the rootViewController and the UIViewController that has just been removed.
What do I need to do? What have I done wrong?
The navigation bar doesn't remember changes that were made to it, so when you push a new controller, the navigation bar is altered to give the title of the new view controller, but it doesn't store what was there for the previous view controller.
You will need to recreate the items in the toolbar each time you come back to the view controller that has custom items.
You might be able to do this on viewWillAppear instead of viewDidLoad. I can't recall exactly, but you should recreate custom controls on navigation toolbar because it does not get preserved when a new view controller is pushed.
It seems that calling popToRootViewController from the rootViewController messes things up. TO rectify this I called the following from within the calling UIViewController
[self.navigationController popViewControllerAnimated:YES];

Back UIButton Controlling UINavigationController

I have looked everywhere for this.
I have a navigation controller. I like using the navigation controller with all the animation however the bar irritates me so i have disabled it.
I would like to create a UIButton that will push the navigation controller back a page instead.
Is this possible? can someone tell me how to achieve this and get hold of the correct item that allows to push back to the previous view.
Thanks
Create a button with a target on a function that do:
[self.navigationController popViewControllerAnimated:YES]
Since navigation controller works as a stack your current view controller is poped out from the stack and the previous view controller is showed
Look at the UINavigationController documentation, you can have your UIButton call the navigation controller's popViewControllerAnimated:
Did you try these methods in the UINavigationController class:
– pushViewController:animated:
– popViewControllerAnimated:
– popToRootViewControllerAnimated:
– popToViewController:animate
Call the pop methods from your button's action method.
Assuming you have a valid reference to the Nav Controller, set up the button action to use:
Pops view controllers until the specified view controller is at the top of the navigation stack.
- (NSArray *)popToViewController:(UIViewController *)viewController animated:(BOOL)animated

Push UITabViewController from UIViewController is possible?

my app first viewController is UIViewController.
and when user click button firstView disappear and push UITabViewController
is it possible?
i can't find how to push UITabViewController from UIViewController.
UPDATE sorry, I misread TabVC for UITableViewController. Do you mean UITableViewController or UITabBarController? I'll leave my answer below anyways.
In this instance, it's usually best to have a UITabBarController be the root view object. Although it can be done, it's a messier implementation, in my opinion.
I would in fact make the UITabBarController the root and display the UIViewController modally from that UITabBarController on launch.
The user would be presented with the UIViewController and when they clicked the button, dismiss that modal view, revealing the UITabBarController.
Just use a UINavigationController.
Use the navigation controller to push the tableView as the second level in the hierarchy. As a bonus you'll get the back button for 'free' and you don't have to worry about delegates for getting back to the original UIViewController.
you may try this:
self.tabBarController.selectedViewController
= [self.tabBarController.viewControllers objectAtIndex:2];
it should work because selectedViewController property contains view of selected tab.
First of all you have view controller . And make Second view controller which contain tabbarcontroller . Now just push second view controller . And add tabbarcontroller's view as a subview to second view controller .
Hope you gets it ..

how to pop a controller off the navigation stack without using the navigation bar

I'm trying to implement a navigation controller with some hierarchical views. I want to use a regular UIViewController to present choices for drilling down, I don't want to use the navigation bar - I want to have my own, custom buttons for returning back up a level.
I see examples like:
[[self navigationController] pushViewController:nextViewController animated:YES];
and my questions are these: Is navigationController a property of all UIViewControllers? Can I refer to self.navigationController regardless of the view that's on the stack? If I'm at an arbitrary view, can I have a button action that contains something like [self.navigationController popToRootViewController animated:YES];
Each view I present will need a button to return to the previous view, or to the root view, depending on the situation. I want to create that button in each view controller and control which view in the stack it returns to. Am I on the right track?
Is navigationController a property of all UIViewControllers?
Yes.
Can I refer to self.navigationController regardless of the view that's on the stack?
Every UIViewController on the UINavigationController's stack will return the UINavigationController object when calling navigationController on it.
If I'm at an arbitrary view, can I have a button action that contains something like [self.navigationController popToRootViewControllerAnimated:YES];
Yes. popToRootViewControllerAnimated: will take the user to the root UIViewController for the UINavigationController, and you can use [self.navigationController popViewControllerAnimated:YES]; to just pop off the top UIViewController. This last one does the same as tapping the Back UIBarButtonItem.
Am I on the right track?
Yes :)

uiview to Uiview switch

I have a uiview class and i want to switch to other uiview class but without using addsubview
is there any other way to do that except the one (addSubView)
If you have UIViewControllers for the corresponding UIViews, and have a UINavigationController to handle your view flow, you can use pushViewController message at the mentioned navigation controller.
Since you have a navigation controller you can use pushViewController:animated to add anotherViewController to the navigation stack. You can also use presentModalViewController:animated. The section on Navigation Controllers in View Controller Programming Guide explains this very well.
