Force Landscape Viewcontroller in iOS 7

Force landscape mode in one ViewController using Swift

It may be useful for others, I found a way to force the view to launch in landscape mode:

Put this in the viewDidLoad():

let value = UIInterfaceOrientation.landscapeLeft.rawValue
UIDevice.current.setValue(value, forKey: "orientation")

and,

override var shouldAutorotate: Bool {
    return true
}

Here is how I forced one of my views to be Landscape using NavigationViewController:

1. Implemented this answer: https://stackoverflow.com/a/12662433/2394787

2. Imported message in the View controller: objc/message.h

3. Added this line of code in the viewDidLoad method:

objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationLandscapeLeft);

Hope it helps someone.

How to force view controller orientation in iOS 8?

For iOS 7 - 10:

Objective-C:

[[UIDevice currentDevice] setValue:@(UIInterfaceOrientationLandscapeLeft) forKey:@"orientation"];
[UINavigationController attemptRotationToDeviceOrientation];

Swift 3:

let value = UIInterfaceOrientation.landscapeLeft.rawValue
UIDevice.current.setValue(value, forKey: "orientation")
UINavigationController.attemptRotationToDeviceOrientation()

Just call it in - viewDidAppear: of the presented view controller.
