tabBarController and navigationControllers in landscape mode, episode II
- by unforgiven
I have a UITabBarController, and each tab handles a different UIViewController that pushes on the stack new controllers as needed. In two of these tabs I need, when a specific controller is reached, the ability to rotate the iPhone and visualize a view in landscape mode. After struggling a lot I have found that it is mandatory subclassing UITabBarController to override shouldAutorotateToInterfaceOrientation. However, if i simply return YES in the implementation, the following undesirable side effect arises:
every controller in every tab is automatically put in landscape mode when rotating the iPhone.
Even overriding shouldAutorotateToInterfaceOrientation in each controller to return NO does not work: when the iPhone is rotated, the controller is put in landscape mode.
I implemented shouldAutorotateToInterfaceOrientation as follows in the subclassed UITabBarController:
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if([self selectedIndex] == 0 || [self selectedIndex] == 3)
return YES;
return NO;
}
So that only the two tabs I am interested in actually get support for landscape mode.
Is there a way to support landscape mode for a specific controller on the stack of a particular tab?
I tried, without success, something like
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if([self selectedIndex] == 0 || [self selectedIndex] == 3)
{
if ([[self selectedViewController] isKindOfClass: [landscapeModeViewController class]])
return YES;
}
return NO;
}
Also, I tried using the delegate method didSelectViewController, without success.
Any help is greatly appreciated.
Thank you.
