问题描述
我们正在使用Xcode 11中的催化剂，将基于Swift的iOS应用转换为Mac 兼容.
We are converting our Swift based iOS app to Mac compatible using Catalyst in Xcode 11.
当用户调整大小应用程序窗口时，我们在用户界面中遇到问题.那么我们可以禁用调整大小模式并为应用程序窗口提供修复框架吗?
We are facing an issue in UI when user resize app window. So can we disable resize mode and give fix frame for app window?
推荐答案
测试版5将sizeRestrictions属性添加到 UIWindowScene .
Beta 5 added a sizeRestrictions property to UIWindowScene.
如果将sizeRestrictions.maximumSize和sizeRestrictions.minimumSize设置为相同的值，则该窗口将无法调整大小:
If you set sizeRestrictions.maximumSize and sizeRestrictions.minimumSize to the same value, the window will not be resizable:
windowScene.sizeRestrictions?.minimumSize = CGSize(width: 640, height: 480)
windowScene.sizeRestrictions?.maximumSize = CGSize(width: 640, height: 480)
添加此代码最简单的位置可能是场景委托中的scene(_:willConnectTo:options:).传入的scene对象是UIWindowScene，因此只需将其强制转换然后设置sizeRestrictions.
The easiest place to add this code is probably scene(_:willConnectTo:options:) in your scene delegate. The scene object passed in is a UIWindowScene, so just cast it and then set sizeRestrictions.
注意:sizeRestrictions仅在iOS 10.15 Beta 5中可用.此代码将在较早的Beta中崩溃.
Note: sizeRestrictions are only available in iOS 10.15 Beta 5. This code will crash in older betas.
