我正在使用消息工具包。在 chatDashbaord 扩展中，我有布尔条件，例如如果 isnewConversation 包含 true，则调用函数 insertConversation2，如果 isnewConversation 包含 false，则调用函数 sendMessag。但是我已经使用断点检查了代码不会进入 isNewconversation 块，我不知道为什么会这样。当我不使用布尔语句时，代码工作文件并将数据附加到数组中，请检查代码谢谢。
消息视图控制器：
class ChatDashboard: MessagesViewController {
var userActive: String? = nil
var receiverName:String? = nil
var isnewConversation = false
var recevierName:String? = nil
var otheruserEmail: String? = nil
var conversationId:String? = nil
var messages : [Message] = []{
didSet{
DispatchQueue.main.async {
self.messagesCollectionView.reloadDataAndKeepOffset()
}
}
扩展 ChatDashboard：
extension ChatDashboard: InputBarAccessoryViewDelegate{
func inputBar(_ inputBar: InputBarAccessoryView, didPressSendButtonWith text: String) {
guard !text.replacingOccurrences(of: "", with: "").isEmpty,let selfSender =
self.selfSender,let messageId = createMessageId() else{
return
}
let message = Message(sender: selfSender, messageId: messageId, sentDate: Date(), kind: .text(text))
guard let otheruserEmail = otheruserEmail,let recevierName = recevierName else {return}
if isnewConversation{
NetworkingService.shared.insertConversation2(with:otheruserEmail,name:recevierName, message: message) { (success) in
if success{
print("message Send")
self.isnewConversation = false
}
else{
print("not send")
}
}
}
else{
guard let converId = conversationId else {return}
NetworkingService.shared.sendMessage(converId,recevierName,message) { (success) in
if success{
print("message send in")
}
else{
print("message not send")
}
}
}
}
}
}
条件为 false 时的 SendMessage func 代码：
func sendMessage(_ convesationId:String,_ name:String,_ message:Message,completion:@escaping(Bool) -> Void){
self.sendMessageReciverToSender(convesationId) { (user) in
guard var receiverToSenderNdoe = user else {completion(false); return}
let dformatter = DateFormatter()
dformatter.dateFormat = "dd/MM/yyy HH:mm"
let dateToString = dformatter.string(from: Date())
guard let email = UserDefaults.standard.value(forKey: "useremail") as? String else {
print("Email not found in user default")
completion(false)
return
}
let currentUserEmail = getUserEmail(currentEmail: email)
var messageData = ""
switch message.kind{
case .text(let messageText):
messageData = messageText
default:
break
}
let newMessge: [String:Any] = [
"id":message.messageId,
"type":message.kind.messageKindString,
"content":messageData,
"date": dateToString,
"sender_email":currentUserEmail,
"is_read":false,
"name":name
]
//issues is here
if var conversationData = receiverToSenderNdoe["messages"] as? [[String:Any]]{
conversationData.append(newMessge)
receiverToSenderNdoe["messages"] = conversationData
self.reciverToSenderSave(convesationId, newMessge) { (result) in
if result{
completion(true)
}
else{
completion(false)
}
}
}
}
}
在 sendMessage func 内部调用了这两个函数
func sendMessageReciverToSender(_ conversationId:String,completion:@escaping([[String:Any]]?) -> Void){
database.child("\(conversationId)/messages").observeSingleEvent(of: .value) { (snapshot) in
if let currentUser = snapshot.value as? [[String:Any]]{
completion(currentUser)
}
else{
print("errro in reciver to sender sendMessageReciverToSender func ")
completion(nil)
}
}
}
func reciverToSenderSave(_ conversationId:String,_ conversation:[[String:Any]],completion:@escaping(Bool)-> Void){
database.child("\(conversationId)/messages").setValue(conversation){(error,ref) in
if error == nil{
completion(true)
}
else{
print("eroor in receiptin \(error?.localizedDescription)")
completion(false)
}
}
}
