I am trying to integrate the SendBird SDK chat with Rubymotion (via its CocoaPod).
The initial steps work fine and I have been able to add the pod to my Rakefile (using motion-cocoapods) and compile with no issues, login users and create a messaging channel. However, the event handler has me stumped.
These are the steps i have been able to translate from the SendBird docs:
Initialize in app delegate
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)
Login to SendBird when signing in / registering in my app
SendBird Objective C:
- (void)viewDidLoad
{
// other setup code
[SendBird loginWithUserId:USER_ID andUserName:USER_NICKNAME];
}
Rubymotion:
(I store user information in Auth.current_user hash once logged in)
SendBird.loginWithUserId(Auth.current_user["id"],andUserName:Auth.current_user["name"])
Create a Messaging Channel and setup an event handler
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:
Here i get in trouble. I am able to create the messaging channel but I have no idea how to write that Objective-C event handler in Rubymotion. The online translator at http://objc2rubymotion.herokuapp.com/ fails due to the ^ and * syntax. Any help is appreciated.
SendBird.startMessagingWithUserId(id_of_target_user)
#Event Handler
EDIT:
A friend who knows more Rubymotion than I do pointed me in the right direction and so now I have the following event handler:
SendBird.startMessagingWithUserId(2)
SendBird.setEventHandlerConnectBlock(
-> (channel) {
# handle connect
},
messagingStartedBlock: -> (channel) {
mp "channel created:" + channel.to_s
})
However this fails with a 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 view_controller.rb:15:in `viewDidLoad'
If I don't include messagingStartedBlock in the Event Handler I get the following error:

from view_controller.rb:15:in `viewDidLoad'
This makes no sense, as setEventHandlerConnectBlock should clearly be a method of the SendBird class.
The relevant SendBird SDK documentation can be found here:
Okay this was solved after a lot of help from a friend.
It turns out that the SendBird Event Handler method needs to be passed ALL event blocks or it will not work. So this will work:
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) { }
)
and will output:
"Messaging started"
#<SendBirdMessagingChannel:0x10f9bcdc0>
Once i get this integration working, I will upload a tutorial / github project.
I will post back the link as a comment once it is done
