SwiftUI CKShare设置为只读的默认权限

Question

我有几个应用程序，包括CloudKit记录共享，现在它似乎在iOS 16中正常工作。

我只包括读、写和读权限选项，并要求共享收件人在用户联系人中。

这似乎确实像预期的那样工作，但是在股票期权中的默认选择是读写。大部分时间我只想读。我无法找到将默认权限从“可以更改”更改为“仅查看”的方法

我的CloudSharingController非常简单：

struct CloudSharingView: UIViewControllerRepresentable {
    let share: CKShare
    let container: CKContainer
    let recipe: Recipe

    func makeCoordinator() -> CloudSharingCoordinator {
        CloudSharingCoordinator(recipe: recipe)
    }

    func makeUIViewController(context: Context) -> UICloudSharingController {
        share[CKShare.SystemFieldKey.title] = recipe.rName
        let controller = UICloudSharingController(share: share, container: container)
        controller.modalPresentationStyle = .formSheet
        controller.delegate = context.coordinator

        controller.availablePermissions = [.allowReadWrite, .allowReadOnly]
        return controller
    }

    func updateUIViewController(_ uiViewController: UICloudSharingController, context: Context) {
    }
}//cloud sharing view

final class CloudSharingCoordinator: NSObject, UICloudSharingControllerDelegate {
    let stack = CoreDataStack.shared
    let recipe: Recipe
    init(recipe: Recipe) {
        self.recipe = recipe
    }

    func itemTitle(for csc: UICloudSharingController) -> String? {
        recipe.rName
    }

    func cloudSharingController(_ csc: UICloudSharingController, failedToSaveShareWithError error: Error) {
        print("Failed to save share: \(error)")
    }

    func cloudSharingControllerDidSaveShare(_ csc: UICloudSharingController) {
        print("Saved the share")
    }

    func cloudSharingControllerDidStopSharing(_ csc: UICloudSharingController) {
        if !stack.isOwner(object: recipe) {
            stack.delete(recipe)
        }
    }
}//cloud sharing coordinator

如有任何指导，将不胜感激。Xcode 14.0，iOS 16.0

Answer 1

availablePermissions似乎有两对选项：

allowPrivate
allowPublic

和

allowReadOnly
allowReadWrite

您需要从每对中指定一个，所以在您的情况下，您需要

controller.availablePermissions = [.allowPrivate, .allowReadWrite]

如果您没有从一对中指定一个，那么它似乎是最允许的选项。
