在iOS中显示新视图和标签栏控制器

Question

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.

Answer 1

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";
}

只需在didSelectRowAtIndexpath：方法中创建一个新的tabbarcontroller视图（就像在应用程序委托中所做的那样）。
