如何在Swift中以编程方式打开icloud应用程序(文件)

import iCloudKit

let container = CKContainer.default()

let database = container.publicCloudDatabase

let query = CKQuery(recordType: "File", predicate: NSPredicate(value: true))

database.perform(query, inZoneWith: nil) { (records, error) in
    if let error = error {
        print("查询失败：\(error.localizedDescription)")
    } else if let records = records {
        for record in records {
            // 处理查询结果
        }
    }
}

for record in records {
    if let fileURL = record["fileURL"] as? CKAsset,
       let fileName = record["fileName"] as? String,
       let fileSize = record["fileSize"] as? Int {
        print("文件名：\(fileName)")
        print("文件大小：\(fileSize) bytes")
        print("文件URL：\(fileURL.fileURL)")
    }
}

let documentInteractionController = UIDocumentInteractionController(url: fileURL.fileURL)
documentInteractionController.presentOptionsMenu(from: view.bounds, in: view, animated: true)
