Force Rotate UIViewController - ios

Question

So, I've given up on trying to solve an issue I've been having where my controller will rotate without calling my shouldAutorotateToInterfaceOrientation: method, because everyone for a few years has been stating it as an iOS bug.
Now I need to just force rotate my UIViewController. Is there a way I can do that, since the UIDevice instance method has been removed now and I don't know what to do to force rotate my controller.

Answer 1

I'm not sure which UIDevice method that you are saying has been removed, but the following has worked for me (this does use the UIDevice orientation method). Bottom line, if you have a view that only accepts landscape, you can use the following to force iOS to change the orientation. It's curious, but it works. I apologize that I can't give credit to the original author, but once came across this elsewhere on StackOverflow:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
- (void)forceLandscape
{
// make sure shouldAutorotateToInterfaceOrientation is configured to accept only landscape
if (UIDeviceOrientationIsPortrait([[UIDevice currentDevice] orientation]))
{
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
UIView *view = [window.subviews objectAtIndex:0];
[view removeFromSuperview];
[window addSubview:view];
}
}
The equivalent to force portrait mode (assuming, of course, your shouldAutorotateToInterfaceOrientation accepts only portrait):
- (void)forcePortrait
{
// make sure shouldAutorotateToInterfaceOrientation is configured to accept only portrait
if (UIDeviceOrientationIsLandscape([[UIDevice currentDevice] orientation]))
{
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
UIView *view = [window.subviews objectAtIndex:0];
[view removeFromSuperview];
[window addSubview:view];
}
}

Answer 2

Using xcode7.3 ios9.
I have been trying to force landscape view on and off for over a week now, no hair left :(. For anyone else finding this question and none of the answers work, or any of the other myriad answers on forcing landscape, I finally found something that works here:
http://www.btday.com/how-to-force-view-controller-orientation-in-ios-8/
Suggestion is to put operation in viewDidAppear, but it also seems to work in viewWillAppear and is slightly less ugly.
override func viewWillAppear(animated: Bool) {
UIDevice.currentDevice().setValue(UIInterfaceOrientation.LandscapeLeft.rawValue, forKey: "orientation")
}
If this is wrong/bad, please speak up, only had a mac for a little over a month so I'm a total nuub!
Also note I'm using a UITabBarController and it doesn't seem to matter whether you put this in the tab bar controller or one of it's children
