iPadOS 13上的屏幕旋转故障 [英] Screen rotation glitch on iPadOS 13

问题描述

我一直在处理iPadOS 13.1.3上与设备方向有关的UI故障.有任何解决方案或解决方法吗?

I've been dealing with a UI glitch on iPadOS 13.1.3 that is related to device orientation. Is there any solution or workaround for this?

说明

让我们让屏幕A模态显示屏幕B.屏幕A仅锁定为纵向，屏幕B支持所有方向.如果显示了屏幕A，则将设备旋转到横向，然后将要显示屏幕B，则屏幕A的尺寸首先会错误地调整大小，这将导致更严重的故障.

Let's have screen A that displays modally screen B. Screen A is locked to portrait only and screen B supports all orientations. If screen A is displayed, device is rotated to landscape then and screen B is about to be displayed, screen A is resized incorrectly first which results a wierd glitch.

在iPadOS 13.2上不再出现故障.

The glitch no longer occurs on iPadOS 13.2.

推荐答案

我像这样解决它:

• 删除您的func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?)实现.让我们让视图控制器来处理这个问题.

• Delete your implementation of func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?). Let's let the view controllers handle this.

在VC1中:

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    .portrait
}

还删除"hacky解决方案".

Also delete the "hacky solution".

在VC2中:

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    .all
}
override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
    .portrait
}

因此，我们得到的是VC2最初以纵向显示，但随后可以旋转.

So what we get is that VC2 appears initially in portrait but can then be rotated.

如果您希望VC2在出现后立即旋转为横向，请添加以下内容:

If you want VC2 to rotate immediately into landscape after appearing, then add this:

var appeared = false
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    appeared = true
    UIViewController.attemptRotationToDeviceOrientation()
}
