iPhone application landscape mode doesn't work

Question

Currently I have only portrait mode in iPhone application. I would like to permit landscape mode for one controller in application but unfortunately I'm not able to make it work.

I have these settings in my plist file:

<array>
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
    <string>UIInterfaceOrientationLandscapeLeft</string>
</array>

And I implemented these methods in my controller:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

-(BOOL)shouldAutorotate
{
   return YES;
}

I use navigation controller in the app so I realize that it might be the problem. I subclassed the UINavigationController and implemented again shouldAutorotateToInterfaceOrientation , supportedInterfaceOrientations and shouldAutorotate in the same way as above. Of course for I use subclassed navigation controller to show the controller which should have ability to rotate. I also tried to overwrite the methods of navigation controller by category but it also doesn't work.

I don't work on the application from the beginning, I inherited the codes. If there is some possibility how to restrict landscape globally it might be my case. For testing I use iPhone 6.0 simulator but my deployment target is 5.0. I appreciate any tips / help.

Answer 1

iOS6 also requires that you set a rootViewController for your window rather than adding the controller's view as a subview.

If you are doing something like this:

[window addSubview:someController.view];

then you can try changing it to this:

[window setRootViewController:someController];

Also look at this link . For ios6, Apple introduced these two methods :

supportedInter

1. faceOrientations:
2. shouldAutorotate

Hope it helps.

Try this on Controller youwant to give landscape orientation

// override to allow orientations other than the default portrait orientation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // return YES for supported orientations
    return UIInterfaceOrientationIsLandscape(interfaceOrientation); // support only landscape
}

1. Go to target window.
2. Click on Summary tab.
3. iPhone/iPad Deployment info -> Set the supported interface orientations for iPhone & iPad as per your requirement. See following image for more reference.
