未显示 iOS 15 通信通知图片 [英] iOS 15 Communication Notification picture not shown

问题描述

我一直在尝试将我的(本地和推送)通知更新为通信通知.

I've been trying to update my (local & push) notifications to Communication notifications.

当用户收到一位朋友的通信事件时，我希望显示的通知包含该朋友的个人资料图片.就像新的 iMessage 应用一样.

When a user receives a communication event from one of their friend, I want the displayed notification to include the friend's profile picture. Just like the new iMessage app does.

在观看了专门的 WWDC2021 会议后，我在我的 SwiftUI 应用中添加了一个 Siri Intent:

After watching the dedicated WWDC2021 session, I added a Siri Intent to my SwiftUI app:

// I correctly added the StartCallIntent to both my app's Info.plist and the Siri Intent extension.
<array>
    <string>INStartCallIntent</string>
</array>

并尝试使用以下内容更新我的通知流程:

and tried to update my notification flow with the following:

let image = INImage(imageData: friend.profilePicture.cellImage.pngData()!)
let intentFriend = INPerson(
  personHandle: INPersonHandle(value: friend.phoneNumber, type: .phoneNumber),
  nameComponents: friend.nameComponents,
  displayName: friend.localName,
  image: image,
  contactIdentifier: nil,
  customIdentifier: nil,
  isMe: false,
  suggestionType: .instantMessageAddress
)

let incomingCommunicationIntent = INStartCallIntent(
  callRecordFilter: nil,
  callRecordToCallBack: nil,
  audioRoute: .unknown,
  destinationType: .normal,
  contacts: [intentFriend],
  callCapability: .audioCall
)

let interaction = INInteraction(intent: incomingCommunicationIntent, response: nil)
interaction.direction = .incoming
interaction.donate(completion: nil)

do {
  let result = try notification.updating(from: incomingCommunicationIntent)
  return result
} catch let error {
  print("-- \(error)")
  // TODO: Handle error here
}

return notification

然后处理返回的 UNNotificationContent 以显示为推送通知或本地通知.

The returned UNNotificationContent is then handled to be displayed either as a push notification or a local one.

虽然上面的代码没有崩溃并且似乎是/work/，但通知看起来没有任何不同.使用调试器查看，_UNNotificationCommunicationContext 已初始化，但是:

While the above code doesn't crash and seems to /work/, the notification doesn't look any different. Looking with a debugger, the _UNNotificationCommunicationContext is initialized, but:

• _displayName 为零
• _recipients 为空(如预期)
• _contentURL 为零
• _attachments 为空
• sender 设置为 UNNotificationContact
  • 句柄 &displayName 设置正确
  • _handleType 似乎也设置正确
  • _displayName is nil
  • _recipients is empty (as expected)
  • _contentURL is nil
  • _attachments is empty
  • sender is set to a UNNotificationContact on which
    • handle & displayName are correctly set
    • _handleType seems correctly set too

    在应用的日志中，我可以看到:

    In the app's logs, I can see:

    [Intents] -[INCache cacheableObjectForIdentifier:] Unable to find cacheable object with identifier EDB29166-E46A-CF23-AB27-8B61F763A039 in cache.
    [Intents] -[INCache cacheableObjectForIdentifier:] Unable to find cacheable object with identifier intents-remote-image-proxy:?proxyIdentifier=EDB29166-E46A-CF23-AB27-8B61F763A039.png&storageServiceIdentifier=com.apple.Intents.INImageServiceConnection in cache.
    

    我缺少什么才能正确显示朋友的个人资料图片?

    What am I missing to correctly display the friend's profile picture?

    谢谢

    推荐答案

    不幸的是，Apple 在记录通信通知方面做得并不好，他们的 WWDC 视频遗漏了大量非常重要的细节，但有一些事情:

    Unfortunately Apple did not do a great job at documenting communication notifications, their WWDC video leaves a ton of very important details out, but there are a few things:

    1. 在您的通知服务扩展的 Info.plist 中，您需要添加以下内容:NSExtension ->NSExtensionAttributes (dict) ->IntentsSupported(数组)->INSendMessageIntent 或 INStartCallIntent.

    1. In your Notification Service Extension's Info.plist you need to add this: NSExtension -> NSExtensionAttributes (dict) -> IntentsSupported (array) -> INSendMessageIntent or INStartCallIntent.

    确保您启用了通信通知"；主要应用目标的能力.

    Make sure you enabled the "Communication Notifications" capability on your main app target.

    最后，你的代码看起来不错，但你需要添加这个(注意:我只测试了 INSendMessageIntent)

    Finally, your code looks right but you need to add this (note: I have only tested this for INSendMessageIntent)

    // Swift
    incomingCommunicationIntent.setImage(image, forParameterNamed: \.sender)
    
    // Objective-C
    [incomingCommunicationIntent setImage:image forParameterNamed:"sender"];
