I am trying to achieve the following but dont know the best way to go about it so any tips would be great.

My app has a first root view which has a tab bar with 4 tabs, one of the tabs contains a table view. When an item is selected on the table view I want to display a details page (which I can do fine) but also completely change the tab bar to match the new set of data.

A good example of this is the free F1 2011 app. When selecting "Live Timing" you are taken to a new screen with a different tab bar (with a home button at the top to get back to previous screen.)

How would be the best way to go about implementing this?

Thanks in advance.

Try linking the the view controller with the table to the new UITabBarController and make it a modal segue. In the class for your viewcontroller with the table do an

#import "FirstViewControllerInNewTabBar"

Then in the 

(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

method you will want to do the following:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    // Since your segue is pointing to the new tab bar controller
    UITabBarController *tabBarController = (UITabBarController *)segue.destinationViewController;  

    // Now you want to pass data into the new tab bar's view controllers
    FirstViewControllerInNewTabBar *vc = (FirstViewControllerInNewTabBar *)[tabBar.viewControllers objectAtIndex:0];

    // Assuming FirstViewControllerInNewTabBar has a property 'NSString *dataToPassIn'
    vc.dataToPassIn = @"Potato";
}

Just create a new tabbarcontroller view (as you would do in the app delegate) in the didSelectRowAtIndexpath: method.

  • Thanks for the info. I have still been having problems with this as the views are switching but my tab bar is not shown or is party covered. But I think that is down to the issue that you cant push a tab bar controller to a navigation controller. I came across the following links which seem to explain this: [link](http://stackoverflow.com/questions/1251981/tab-bar-will-no-work-as-a-subview-of-another-view-but-works-fine-as-a-subview-of) – Fraser Apr 17 '11 at 10:50
