How to control interface orientation?

[mradlmaier]

I want that my app runs in portrait mode except for a view scenes/View controllers

Normally one would enable all orientations in the Deployment infos, and then, in each view controller:

-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskAllButUpsideDown;
} // in the view controllers which support both

and

-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
} // in the view controllers, which should only support portrait mode

However, this method (in iOS7) only gets called on the root view controller (according to apple docs).
This is the SASlideMenuRootViewController, and I tested it, it seems, this is the only controller in which above method is called.

Now, how do I know when this method is called, which view controller is about to be presented?

Hi mradlmaier,

sorry for the late replay. I am not sure I understood correctly. If you need to rotate the interface depending on the currently selected content view controller maybe the solution suggested in http://stackoverflow.com/questions/20355089/shouldautorotate-supportedinterfaceorientations-and-preferredinterfaceorientati will work.
In the SASlideMenu case you will need to subclass SASlideMenuRootViewController and do something like:

- (BOOL)shouldAutorotate {
    UIViewController* topController =  [self.selectedContent  topViewController];
    return [topController shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations {
    UIViewController* topController =  [self.selectedContent  topViewController];

    return [topController supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    UIViewController* topController =  [self.selectedContent  topViewController];
    return [topController preferredInterfaceOrientationForPresentation];
}

But I do not have the time to test it now.

I want that some view controllers are in Landscape/Portrait and others only in Portrait.

The stackoverflow.com post doesn't work. I tried a few other similiar solutions and they don't work in a SASlideMenu Project, but work in normal projects. I believe it has to do with SASlideMenu.

Thinking a little more about it, my conclusion is that it is not possible to have SASlideMenu to support different orientation for different content controller.
If you want a view controller that can be in landscape and another only in portrait what should be the behaviour when you exit from one controller that is in landscape and you switch to the other controller that cannot be in landscape?
The menu will be rotated and so will be the content controller.
Currently SASlideMenu only support one behaviour at time.

[mradlmaier]

I understand. The only way would be that the menu supports all orientations, and, when exiting a view controller, the menu rotates to the last view controllers orientation. Maybe users might find it confusing. However, would be nice, if one could see it in action to make up one's mind if it is good or not...

I think it will be confusing. What you can do is when you need a landscape view you present it modally. That way it will be responsibility of the specific view controller to define the orientation behaviour, that view should be presented from a content view controller.

[mradlmaier]

I would present it modally, but it is a little more complicated. The view controller, which I want to present in landscape, is contained in a tabbar controller, so I can't present it modally.
