使用 UIApplicationDelegateAdaptor 从 userDidAcceptCloudKitShareWith 获取回调无效
Using UIApplicationDelegateAdaptor to get callbacks from userDidAcceptCloudKitShareWith not working
我正在尝试在 userDidAcceptCloudKitShareWith
被呼叫时收到通知。传统上这是在 App Delegate
中调用的,但由于我正在构建一个 iOS 14+,使用 App
作为我的根对象。关于如何将 userDidAcceptCloudKitShareWith
添加到我的应用程序 class,我找不到任何文档,所以我使用 UIApplicationDelegateAdaptor
来使用 App Delegate
class,但似乎 userDidAcceptCloudKitShareWith
从未被调用过?
import SwiftUI
import CloudKit
// Our observable object class
class ShareDataStore: ObservableObject {
static let shared = ShareDataStore()
@Published var didRecieveShare = false
@Published var shareInfo = ""
}
@main
struct SocialTestAppApp: App {
@StateObject var shareDataStore = ShareDataStore.shared
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView().environmentObject(shareDataStore)
}
}
}
class AppDelegate: NSObject, UIApplicationDelegate {
let container = CKContainer(identifier: "iCloud.com.TestApp")
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
print("did finish launching called")
return true
}
func application(_ application: UIApplication, userDidAcceptCloudKitShareWith cloudKitShareMetadata: CKShare.Metadata) {
print("delegate callback called!! ")
acceptShare(metadata: cloudKitShareMetadata) { result in
switch result {
case .success(let recordID):
print("successful share!")
ShareDataStore.shared.didRecieveShare = true
ShareDataStore.shared.shareInfo = recordID.recordName
case .failure(let error):
print("failure in share = \(error)")
}
} }
func acceptShare(metadata: CKShare.Metadata,
completion: @escaping (Result<CKRecord.ID, Error>) -> Void) {
// Create a reference to the share's container so the operation
// executes in the correct context.
let container = CKContainer(identifier: metadata.containerIdentifier)
// Create the operation using the metadata the caller provides.
let operation = CKAcceptSharesOperation(shareMetadatas: [metadata])
var rootRecordID: CKRecord.ID!
// If CloudKit accepts the share, cache the root record's ID.
// The completion closure handles any errors.
operation.perShareCompletionBlock = { metadata, share, error in
if let _ = share, error == nil {
rootRecordID = metadata.rootRecordID
}
}
// If the operation fails, return the error to the caller.
// Otherwise, return the record ID of the share's root record.
operation.acceptSharesCompletionBlock = { error in
if let error = error {
completion(.failure(error))
} else {
completion(.success(rootRecordID))
}
}
// Set an appropriate QoS and add the operation to the
// container's queue to execute it.
operation.qualityOfService = .utility
container.add(operation)
}
}

看看这个问题,它有很多有用的东西可以检查几个可能的答案:
CloudKit CKShare userDidAcceptCloudKitShareWith Never Fires on Mac App
确保将 CKSharingSupported
键添加到 info.plist,然后尝试使用上述 link 中的答案将 userDidAcceptCloudKitShareWith
放在不同的位置(其中你把它取决于你正在构建什么样的应用程序)。
在 Scene-based
应用程序中,userDidAcceptCloudKitShareWith
回调被发布到场景委托,但在 SwiftUI 2.0 App-based
应用程序中,SwiftUI 本身使用场景委托来提供 scenePhase
事件,但不提供处理主题回调的本机方式。
解决这个问题的可能方法是找到一个 window 并注入自己的场景委托包装器,它将处理 userDidAcceptCloudKitShareWith
并将其他人转发给原始 SwiftUI 委托(以保持标准 SwiftUI 事件工作) .
这里有几个基于 window 访问的演示快照(但是您可以使用任何其他更好的方式来获取 window)

struct athlyticSocialTestAppApp: App {
@StateObject var shareDataStore = ShareDataStore.shared
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
let sceneDelegate = MySceneDelegate()
var body: some Scene {
WindowGroup {
ContentView().environmentObject(shareDataStore)
.withHostingWindow { window in
sceneDelegate.originalDelegate = window?.windowScene.delegate
window?.windowScene.delegate = sceneDelegate
}
}
}
}
class MySceneDelegate : NSObject, UIWindowSceneDelegate {
var originalDelegate: UISceneDelegate?
func windowScene(_ windowScene: UIWindowScene, userDidAcceptCloudKitShareWith cloudKitShareMetadata: CKShareMetadata) {
// your code here

// forward all other UIWindowSceneDelegate/UISceneDelegate callbacks to original, like

originalDelegate?.scene(scene, willConnectTo: session, options: connectionOptions)
