iOS：默认的IB popover转换做的很奇怪
我碰到了一个奇怪的问题，当一个视图控制器出现在一个弹出框中时，呈现视图控制器view不会被捕捉到它的超视图的底边，在这种情况下window 1}}本身。
AppDelegate代码：
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let window = UIWindow(frame: UIScreen.main.bounds)
window.rootViewController = UIStoryboard(name: "NavigationController", bundle: Bundle.main).instantiateInitialViewController()
window.makeKeyAndVisible()
window.backgroundColor = .yellow // Needed to detect the issue.
self.window = window
return true
}
要测试的故事板：

复制新项目中的所有内容，删除main作为要启动的主要故事板。
- 在iPhone X Plus模拟器（或真实设备）上运行项目。
- 单击底部以显示视图控制器。 2.1。启用慢动作（仅限模拟器）。
- 旋转您的设备。
我正在谈论的问题是黄色view可见（window）。一次旋转确实正确地布局了呈现视图控制器，另一次旋转确实以错误的状态开始。
这是我的故事板中的错误还是来自UIKit的错误？
更新：该项目使用最新的iOS SDK并且没有弃用的API（如上所示＆＃39;几乎所有内容都是使用IB＆＃39;构建的）。
更新2：我更新了原始句子，以明确表示 <{1}}
