Question

I’m pretty new to Objective-C and I’m working on a webradio app.

My app is composed of some NavigationControllers included in a TabBarController.

I want to make a View wich would stay just above the TabBar ALL THE TIME. (it will contain the audio player controls and must be accessible anywhere in the app)

What would be the best way to do so?

Thanks!

You need to add your view as a subview of the UITabBarController view property:

m_yourToolbar =[[UIToolbar alloc] initWithFrame:CGRectMake(0, 401, 320, 44)];
// set some properties on the toolbar
// ...
[self.tabBarController.view m_yourToolbar];

This adds the UILabel blah over the content for every tab in the UITabBarController (m_tabBarController).

@interface YouAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
    UIToolbar * m_yourToolbar;

    // ... whatever other stuff you have in your app delegate
}

@property (nonatomic, retain) UIToolbar * yourToolbar;

In your app delegate implementation you will need:

@synthesize yourToolbar= m_yourToolbar;
// .. other app delegate stuff

So in your view controllers that need to update the toolbar, you can get hold of the app delegate, grab the yourToolbar property and set attributes on it:

AppDelegate *appDelegate = (YouAppDelegate *)[[UIApplication sharedApplication] delegate];
// set stuff on the toolbar property
appDelegate.yourToolbar.stuff = stuff;
