我现在搜索了一天,但没有找到合适的解决方案。
我的应用程序内部包含一个标签栏控制器和导航控制器。
我只希望所有屏幕都是“纵向”,但只有一个子视图是“横向”。
它可以到达那里,但是当我从子视图返回时,实际上仍然保持横向,即使我只允许.portrait ind控制器,父级也显示为横向。
我已经做了:
extension UITabBarController {
override open var shouldAutorotate: Bool {
get {
if let visibleVC = selectedViewController {
return visibleVC.shouldAutorotate
}
return super.shouldAutorotate
}
}
override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
get {
if let visibleVC = selectedViewController {
return visibleVC.preferredInterfaceOrientationForPresentation
}
return super.preferredInterfaceOrientationForPresentation
}
}
override open var supportedInterfaceOrientations: UIInterfaceOrientationMask {
// your custom logic for rotation of selected tab
get {
if let visibleVC = selectedViewController {
return visibleVC.supportedInterfaceOrientations
}
return super.supportedInterfaceOrientations
}
}
}
extension UINavigationController {
override open var shouldAutorotate: Bool {
get {
if let visibleVC = visibleViewController {
return visibleVC.shouldAutorotate
}
return super.shouldAutorotate
}
}
override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
get {
if let visibleVC = visibleViewController {
return visibleVC.preferredInterfaceOrientationForPresentation
}
return super.preferredInterfaceOrientationForPresentation
}
}
override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
get {
if let visibleVC = visibleViewController {
return visibleVC.supportedInterfaceOrientations
}
return super.supportedInterfaceOrientations
}
}
}
并在父控制器中:
override var shouldAutorotate: Bool{
return true
}
override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
return .portrait
}
override var supportedInterfaceOrientations: UIInterfaceOrientationMask{
return .portrait
}
当我将设备转到纵向时,视图将再次以纵向显示,但我希望在孩子横向离开后立即进行,即使我不转动设备也是如此。
有任何想法吗?
谢谢!
最佳答案
在您的Landscape View控制器中添加此代码
override func viewDidLoad() {
super.viewDidLoad()
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.myOrientation = .landscapeRight
}
和ViewWillDisappear添加此
override func viewWillDisappear(_ animated: Bool) {
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.myOrientation = .portrait
UIView.setAnimationsEnabled(false)
UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")
UIView.setAnimationsEnabled(true)
UIViewController.attemptRotationToDeviceOrientation()
UIView.setAnimationsEnabled(false)
}
在appDeledate中添加此行
var window: UIWindow?
var myOrientation: UIInterfaceOrientationMask = .portrait
