敬上
安裝或更新專案的 Pod 後,請務必開啟 Xcode
專案 .xcworkspace。
在應用程式中匯入 Firebase:

importFirebase
Objective-C
@importFirebase;
1. 建立對話記錄物件
如要產生智慧回覆功能,您必須傳送 ML Kit 依時間順序排序的
TextMessage 物件,具有最早的時間戳記。每當使用者
新增或接收訊息、新增訊息、其時間戳記以及
並將傳送者的使用者 ID 加入對話記錄中。
使用者 ID 可以是任何能用來識別
對話。User-ID 不需要對應至任何使用者資料
而且使用者 ID 不必保持一致
叫用智慧回覆產生器。
如果訊息是由您想建議回覆的使用者所寄送,請設定
isLocalUser 設為 true。
Swift
varconversation:[TextMessage]=[]// Then, for each message sent and received:letmessage=TextMessage(text:"How are you?",timestamp:Date().timeIntervalSince1970,userID:"userId",isLocalUser:false)conversation.append(message)
Objective-C
NSMutableArray*conversation=[NSMutableArrayarray];// Then, for each message sent and received:FIRTextMessage*message=[[FIRTextMessagealloc]initWithText:@"How are you?"timestamp:[NSDatedate].timeIntervalSince1970userID:userIdisLocalUser:NO];[conversationaddObject:message];
對話記錄物件如下列範例所示:

抱歉,我遲到了!
請注意,上述範例中最新的訊息並非來自本機
內容。這很重要,因為 ML Kit 建議要傳送的回覆
也就是本機使用者確定自己能順利通過
ML Kit 對話記錄,此記錄的結尾是使用者可能前往的訊息
也就是您要回覆的對象。

If ML Kit determines the conversation is in English, and that\nthe conversation doesn't have potentially sensitive subject matter, ML Kit\ngenerates up to three replies, which you can suggest to your user.\n\n\u003cbr /\u003e\n\nBefore you begin\n----------------\n\n1. If you have not already added Firebase to your app, do so by following the steps in the [getting started guide](/docs/ios/setup).\n2. Include the ML Kit libraries in your Podfile: \n\n ```\n pod 'Firebase/MLCommon', '6.25.0'\n pod 'Firebase/MLNLSmartReply', '6.25.0'\n ```\n After you install or update your project's Pods, be sure to open your Xcode project using its `.xcworkspace`.\n3. In your app, import Firebase: \n\n #### Swift\n\n ```swift\n import Firebase\n ```\n\n #### Objective-C\n\n ```objective-c\n @import Firebase;\n ```\n\n1. Create a conversation history object\n---------------------------------------\n\nTo generate smart replies, you pass ML Kit a chronologically-ordered array of\n`TextMessage` objects, with the earliest timestamp first. Whenever the user\nsends or receives a message, add the message, its timestamp, and the message\nsender's user ID to the conversation history.\n\nThe user ID can be any string that uniquely identifies the sender within the\nconversation. The user ID doesn't need to correspond to any user data,\nand the user ID doesn't need to be consistent between conversations or\ninvocations of the smart reply generator.\n\nIf the message was sent by the user you want to suggest replies to, set\n`isLocalUser` to true. \n\n### Swift\n\n var conversation: [TextMessage] = []\n\n // Then, for each message sent and received:\n let message = TextMessage(\n text: \"How are you?\",\n timestamp: Date().timeIntervalSince1970,\n userID: \"userId\",\n isLocalUser: false)\n conversation.append(message)\n\n### Objective-C\n\n NSMutableArray *conversation = [NSMutableArray array];\n\n // Then, for each message sent and received:\n FIRTextMessage *message = [[FIRTextMessage alloc]\n initWithText:@\"How are you?\"\n timestamp:[NSDate date].timeIntervalSince1970\n userID:userId\n isLocalUser:NO];\n [conversation addObject:message];\n\nA conversation history object looks like the following example:\n\n| Timestamp | User ID | Local User? | Message |\n|------------------------------|---------|-------------|----------------------|\n| Thu Feb 21 13:13:39 PST 2019 | | true | are you on your way? |\n| Thu Feb 21 13:15:03 PST 2019 | FRIEND0 | false | Running late, sorry! |\n\nNote that the most recent message in the example above is from a non-local\nuser. This is important because ML Kit suggests replies intended to be sent\nby the user of your app: the local user. You should be sure you're passing\nML Kit a conversation log that ends with a message to which your user might\nwant to reply.\n\n2. Get message replies\n----------------------\n\nTo generate smart replies to a message, get an instance of `SmartReply` and pass\nthe conversation history to its `suggestReplies(for:completion:)` method: \n\n### Swift\n\n let naturalLanguage = NaturalLanguage.naturalLanguage()\n naturalLanguage.smartReply().suggestReplies(for: conversation) { result, error in\n guard error == nil, let result = result else {\n return\n }\n if (result.status == .notSupportedLanguage) {\n // The conversation's language isn't supported, so the\n // the result doesn't contain any suggestions.\n } else if (result.status == .success) {\n // Successfully suggested smart replies.\n // ...\n }\n }\n\n### Objective-C\n\n FIRNaturalLanguage *naturalLanguage = [FIRNaturalLanguage naturalLanguage];\n FIRSmartReply *smartReply = [naturalLanguage smartReply];\n [smartReply suggestRepliesForMessages:inputText\n completion:^(FIRSmartReplySuggestionResult * _Nullable result,\n NSError * _Nullable error) {\n if (error || !result) {\n return;\n }\n if (result.status == FIRSmartReplyResultStatusNotSupportedLanguage) {\n // The conversation's language isn't supported, so the\n // the result doesn't contain any suggestions.\n } else if (result.status == FIRSmartReplyResultStatusSuccess) {\n // Successfully suggested smart replies.\n // ...\n }\n }];\n ]\n\nIf the operation succeeds, a `SmartReplySuggestionResult` object is passed to\nthe completion handler. This object contains a list of up to 3 suggested\nreplies, which you can present to your user: \n\n### Swift\n\n for suggestion in result.suggestions {\n print(\"Suggested reply: \\(suggestion.text)\")\n }\n\n### Objective-C\n\n for (FIRSmartReplySuggestion *suggestion in result.suggestions) {\n NSLog(@\"Suggested reply: %@\", suggestion.text);\n }\n\nNote that ML Kit might not return results if the model isn't confident in\nthe relevance of the suggested replies, the input conversation isn't in\nEnglish, or if the model detects sensitive subject matter.\n| **Known issue**: Currently, on 32-bit iOS devices, ML Kit doesn't return suggestions for any input."]]
