SendBird 聊天 SDK Rubymotion 集成

Question

我正在尝试将 SendBird SDK 聊天与 Rubymotion 集成（通过其 CocoaPod）。

初始步骤工作正常，我已经能够将 pod 添加到我的 Rakefile（使用 motion-cocoapods）并编译没有问题，登录用户并创建消息通道。然而，事件处理程序让我难住了。

这些是我能够从 SendBird 文档翻译的步骤：

在应用委托中初始化

SendBird Objective C:

#import <SendBirdSDK/SendBirdSDK.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // ...
    NSString *APP_ID = @"<YOUR_APP_ID>"; // You could get it from SendBird Dashboard.
    [SendBird initAppId:APP_ID];
    // ...
    return YES;
}

Rubymotion:

APP_ID = "xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx"
SendBird.initAppId(APP_ID)

在我的应用程序中登录/注册时登录 SendBird

SendBird Objective C:

- (void)viewDidLoad
{    
    // other setup code
    [SendBird loginWithUserId:USER_ID andUserName:USER_NICKNAME];   
}

Rubymotion:

（登录后我将用户信息存储在 Auth.current_user 哈希中）

SendBird.loginWithUserId(Auth.current_user["id"],andUserName:Auth.current_user["name"])

创建消息通道并设置事件处理程序

SendBird Objective C:

[SendBird startMessagingWithUserId:targetUserId]; // 1 on 1 channel

// In your event handler
[SendBird setEventHandlerConnectBlock:^(SendBirdChannel *channel) {
    // Callback for [SendBird connectWithTS:] or [SendBird connect:]
} errorBlock:^(NSInteger code) {
    // Error occured due to bad APP_ID (or other unknown reason)
} channelLeftBlock:^(SendBirdChannel *channel) {
    // Callback for [SendBird leaveChannel:]
} messageReceivedBlock:^(SendBirdMessage *message) {
    // Received a regular chat message
} fileReceivedBlock:^(SendBirdFileLink *fileLink) {
    // Received a file
} messagingStartedBlock:^(SendBirdMessagingChannel *channel) {
    // Callback for [SendBird startMessagingWithUserId:] or [SendBird inviteMessagingWithChannelUrl:]
} messagingUpdatedBlock:^(SendBirdMessagingChannel *channel) {
    // Callback for [SendBird inviteMessagingWithChannelUrl:]
} messagingEndedBlock:^(SendBirdMessagingChannel *channel) {
    // Callback for [SendBird endMessagingWithChannelUrl:]
} allMessagingEndedBlock:^ {
    // Callback for [SendBird endAllMessaging:]
} readReceivedBlock:^(SendBirdReadStatus *status) {
    // When ReadStatus has been received
} messageDeliveryBlock:^(BOOL send, NSString *message, NSString *data, NSString *tempId{
   // To determine the message has been successfully sent.
} mutedMessagesReceivedBlock:^(SendBirdMessage *message) {
   // When soft-muted messages have been received
} mutedFileReceivedBlock:^(SendBirdFileLink *message) {
   // When soft-muted files have been received
}];

Rubymotion:

我遇到麻烦了。我能够创建消息通道，但我不知道如何在 Rubymotion 中编写 Objective-C 事件处理程序。 http://objc2rubymotion.herokuapp.com/ 的在线翻译器因 ^ 和 * 语法而失败。感谢任何帮助。

SendBird.startMessagingWithUserId(id_of_target_user)

#Event Handler

编辑：

一位比我更了解 Rubymotion 的朋友为我指出了正确的方向，所以现在我有了以下事件处理程序：

SendBird.startMessagingWithUserId(2)

SendBird.setEventHandlerConnectBlock(
    -> (channel) {
            # handle connect
    },
    messagingStartedBlock: -> (channel) {
      mp "channel created:" + channel.to_s
    })

然而，这失败了，出现了 NoMethodError:

2016-08-03 19:48:58.711 faces_ios_v1[75673:798798] chat_screen.rb:24:in `on_load': undefined method `setEventHandlerConnectBlock:messagingStartedBlock:' for SendBird:Class (NoMethodError)
    from screen_module.rb:39:in `view_did_load'
    from view_controller.rb:15:in `viewDidLoad'
2016-08-03 19:48:58.723 faces_ios_v1[75673:798798] *** Terminating app due to uncaught exception 'NoMethodError', reason: 'chat_screen.rb:24:in `on_load': undefined method `setEventHandlerConnectBlock:messagingStartedBlock:' for SendBird:Class (NoMethodError)
    from screen_module.rb:39:in `view_did_load'
    from view_controller.rb:15:in `viewDidLoad'

如果我不在事件处理程序中包含 messagingStartedBlock，我会收到以下错误：

2016-08-03 19:35:20.120 faces_ios_v1[74958:793380] chat_screen.rb:14:in `on_load': undefined method `setEventHandlerConnectBlock' for SendBird:Class (NoMethodError)
    from screen_module.rb:39:in `view_did_load'
    from view_controller.rb:15:in `viewDidLoad'
2016-08-03 19:35:20.132 faces_ios_v1[74958:793380] *** Terminating app due to uncaught exception 'NoMethodError', reason: 'chat_screen.rb:14:in `on_load': undefined method `setEventHandlerConnectBlock' for SendBird:Class (NoMethodError)
    from screen_module.rb:39:in `view_did_load'
    from view_controller.rb:15:in `viewDidLoad'

这没有意义，因为 setEventHandlerConnectBlock 显然应该是 SendBird class 的一个方法。

相关的SendBird SDK文档可以在这里找到：

好的，在朋友的大力帮助下解决了这个问题。

事实证明，SendBird 事件处理程序方法需要传递所有事件块，否则将无法工作。所以这会起作用：

  SendBird.startMessagingWithUserId(2)

    SendBird.setEventHandlerConnectBlock(
  -> (channel) { },
  errorBlock: -> (code) { },
  channelLeftBlock: -> (channel) { },
  messageReceivedBlock: -> (message) { },
  systemMessageReceivedBlock: -> (message) { },
  broadcastMessageReceivedBlock: -> (message) { },
  fileReceivedBlock: -> (file_link) { },
  messagingStartedBlock: -> (channel) {
    mp "Messaging started"
    mp channel
   },
  messagingUpdatedBlock: -> (channel) { },
  messagingEndedBlock: -> (channel) { },
  allMessagingEndedBlock: -> { },
  messagingHiddenBlock: -> (channel) { },
  allMessagingHiddenBlock: -> { },
  readReceivedBlock: -> (status) { },
  typeStartReceivedBlock: -> (status) { },
  typeEndReceivedBlock: -> (status) { },
  allDataReceivedBlock: -> (sendBirdDataType, count) { },
  messageDeliveryBlock: -> (send, message, data, temp_id) { },
  mutedMessagesReceivedBlock: -> (message) { },
  mutedFileReceivedBlock: -> (message) { }
)

并将输出：

"Messaging started"
#<SendBirdMessagingChannel:0x10f9bcdc0>

此集成工作后，我将上传一个教程/github 项目。
