iOS只旋转某一个页面

只旋转某一个页面

下面的代码只支持 self.present(vc, animated: true, completion: nil) 展现的页面，才可以旋转

 

在 UINavigationController 中重写下面方法

override var shouldAutorotate: Bool{
    return self.topViewController?.shouldAutorotate ?? false
}
override var supportedInterfaceOrientations: UIInterfaceOrientationMask{
    return self.topViewController?.supportedInterfaceOrientations ?? .portrait
}
override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
    return self.topViewController?.preferredInterfaceOrientationForPresentation ?? .portrait
}

  在 UITabBarController 中重写下面方法

override var shouldAutorotate: Bool{
    return self.selectedViewController?.shouldAutorotate ?? false
}
override var supportedInterfaceOrientations: UIInterfaceOrientationMask{
    return self.selectedViewController?.supportedInterfaceOrientations ?? .portrait
}
override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
    return self.selectedViewController?.preferredInterfaceOrientationForPresentation ?? .portrait
}

 

然后在需要旋转的页面中加入下面代码

override var shouldAutorotate: Bool{
    return true
}
override var supportedInterfaceOrientations: UIInterfaceOrientationMask{
    return UIInterfaceOrientationMask.landscapeRight
}
override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
    return .landscapeRight
}
