如何在visionOS的SwiftUI中以编程方式关闭指定标识的窗口？

首先，确保你的MyData结构体遵循Codable和Hashable协议——这是WindowGroup标识类型的必备要求：

struct MyData: Codable, Hashable {
    let intValue: Int
    let stringValue: String
}

对应的WindowGroup定义示例：

@main
struct MyVisionProApp: App {
    var body: some Scene {
        WindowGroup(for: MyData.self) { $data in
            MyCustomView(data: data)
        }
        
        // 其他窗口组...
    }
}

要编程关闭这类窗口，核心思路是通过UIApplication获取所有场景会话，过滤出关联MyData标识的会话后销毁，具体实现如下：

关闭所有MyData标识的窗口 #

import UIKit

func closeAllMyDataWindows() {
    guard let app = UIApplication.shared as? UIApplication else { return }
    
    // 筛选出所有带MyData标识的窗口场景会话
    let targetSessions = app.connectedScenes
        .compactMap { $0 as? UIWindowScene }
        .map { $0.session }
        .filter { session in
            guard let userActivity = session.userActivity,
                  let data = userActivity.userInfo?[NSUserActivityTypeKey] as? Data else {
                return false
            }
            // 尝试解码验证是否为MyData类型
            return (try? JSONDecoder().decode(MyData.self, from: data)) != nil
        }
    
    // 逐个销毁会话（对应关闭窗口）
    targetSessions.forEach {
        app.requestSceneSessionDestruction($0, options: nil)
    }
}

关闭特定匹配的MyData窗口 #

如果需要精准关闭某一个（或某一批）符合条件的窗口，只需修改过滤逻辑：

func closeTargetMyDataWindow(targetInt: Int, targetString: String) {
    guard let app = UIApplication.shared as? UIApplication else { return }
    
    let targetSessions = app.connectedScenes
        .compactMap { $0 as? UIWindowScene }
        .map { $0.session }
        .filter { session in
            guard let userActivity = session.userActivity,
                  let data = userActivity.userInfo?[NSUserActivityTypeKey] as? Data,
                  let myData = try? JSONDecoder().decode(MyData.self, from: data) else {
                return false
            }
            // 匹配目标参数
            return myData.intValue == targetInt && myData.stringValue == targetString
        }
    
    targetSessions.forEach {
        app.requestSceneSessionDestruction($0, options: nil)
    }
}

注意事项 #

• requestSceneSessionDestruction是异步操作，窗口不会立即关闭
• 调用方法时需确保应用处于活跃状态，场景会话已加载
• 若自定义了WindowGroup的userActivity类型，需调整NSUserActivityTypeKey对应的键值
