我研究了所有这些Swift,asp.net和javascript问题。
目标:
当我从MessageListController
中的聊天消息列表中选择一条消息时,我希望下一个ChatDetailController
中打开的会话是所选的会话。
我在此iOS图像中为WatchKit应用执行相同的操作。选择与Sophia的消息,并打开与Sophia的聊天。 [![在此处输入图片描述] [6]] [6]
我想传递json“ message_id”,即chatMessageId
属性。如您在代码中所见,我已经将chatMessageId
从MessageModel
传递到ChatDetailController
。
我需要通过chatMessageId
的{{1}}吗?还是我已经传递了所需的数据?
传递的上下文:可选(HTWatch_Extension.MessageModel(合作伙伴:“ 9859”,昵称:“马可”,消息:“您看到过狗吗?”,城市:“ Madrid”,countryBadgeImageURL:https://i.imgur.com/PJcyle7.jpg,messageListImageURL :https://i.imgur.com/PJcyle7.jpg,chatMessageId:“ Tva9d2OJyWHRC1AqEfKjclRwXnlRDQ”,状态:“离线”))
尝试:
我是否需要从ChatModel
的{{1}}方法中解析ChatModel
的do-catch块中放入{{ 1}}?

如果我正确理解,您的Chat.json
将拥有所有消息ID的聊天记录。选择消息ID行之一,并加载各自的聊天记录。
在这种情况下,您可以使用filter
根据消息进行解析。假设您在这样的字典中有它。
示例:
let responseString = "{\"name\":\"Tom\"}"
if let responseData = responseString.data(using: .utf8){
do {
let object = try JSONSerialization.jsonObject(with:responseData , options: .allowFragments)
print("Response Object=\(object)")
} catch{
print("parsing Error=\(error)")
}
}
您可以使用类似的代码创建对象。最终对象应类似于chatDictionary
let chatDictionary = [
[
"fromId": "zz1234skjksmsjdfwe2zz",
"toId": "qq43922sdkfjsfmmxdfqq",
"messageText": "Have you seen is dog?",
"imageUrl": "https://i.imgur.com/PJcyle7.jpg",
"message_id": "Tva9d2OJyWHRC1AqEfKjclRwXnlRDQ",
"read": "true"
],
[
"fromId": "zz1234skjksmsjdfwe2zz",
"toId": "qq43922sdkfjsfmmxdfqq",
"messageText": "Yes I have. It's cute.",
"imageUrl": "https://i.imgur.com/PJcyle7.jpg",
"message_id": "Tva9d2OJyWHRC1AqEfKjclRwXnlRDQ",
"read": "true"
],
[
"fromId": "zz1234skjksmsjdfwe2zz",
"toId": "qq43922sdkfjsfmmxdfqq",
"messageText": "I want to get a pet too.",
"imageUrl": "https://i.imgur.com/PJcyle7.jpg",
"message_id": "Tva9d2OJyWHRC1AqEfKjclRwXnlRDQ1",
"read": "true"
]
]
您确实选择了索引行
override func table(_ table: WKInterfaceTable, didSelectRowAt rowIndex: Int) {
let message = messageObjects[rowIndex]
// Create a chat object Dictionary, parse it before you pass it to the detail View Controller , if you have the chat.json.
// I have used 'Tva9d2OJyWHRC1AqEfKjclRwXnlRDQ', but here you can your message id property to make it dynamic
message.chatObjects= chatDictionary.filter { (dictionaryTemp:[String : String]) -> Bool in
return dictionaryTemp["message_id"] == "Tva9d2OJyWHRC1AqEfKjclRwXnlRDQ"
}
presentController(withName: "ChatDetailController", context: message)
}
