Set message content

The current iOS SDK does not expose a standalone NCEngine.setMessageContent(...) API.

To update a message through the published API surface, use BaseChannel.updateMessage(params:completion:) (Objective-C selector: +[NCBaseChannel updateMessageWithParams:completion:]) with UpdateMessageParams (NCUpdateMessageParams in Objective-C).

Update a message

Method signature

Swift

swift

import NexconnChatSDK

static func updateMessage(
    params: UpdateMessageParams,
    completion: ((Message?, NCError?) -> Void)?
)
// Called as: BaseChannel.updateMessage(params:completion:)

Objective-C

Objective C

+ (void)updateMessageWithParams:(NCUpdateMessageParams *)params
                     completion:(nullable void (^)(NCMessage * _Nullable message, NCError * _Nullable error))completion;

Parameters

Parameter	Type	Description
params	NCUpdateMessageParams *	Update parameters. messageId is required and identifies the server message to update. content is required and contains the replacement NCMessageContent.
completion	Block	Completion callback. Returns NCMessage on success, or NCError on failure.

Return value

The completion callback returns the updated NCMessage object on success.

Source-aligned notes

• The current public SDK exposes updateMessageWithParams:completion: and does not expose a separate setMessageContent API.
• NCUpdateMessageParams contains only messageId and content. Public params do not include objectName or searchWords.

Example

Swift

swift

import NexconnChatSDK

let content = TextMessage(text: "Updated message body")
let params = UpdateMessageParams(messageId: "message_id", content: content)

BaseChannel.updateMessage(params: params) { message, error in
    if let error {
        print("Failed to update message: \(error.localizedDescription)")
    } else {
        print("Updated message: \(message?.messageId ?? "")")
    }
}

Objective-C

Objective C

NCTextMessage *content = [[NCTextMessage alloc] initWithText:@"Updated message body"];
NCUpdateMessageParams *params =
    [[NCUpdateMessageParams alloc] initWithMessageId:@"message_id" content:content];

[NCBaseChannel updateMessageWithParams:params
                            completion:^(NCMessage * _Nullable message, NCError * _Nullable error) {
    if (error == nil) {
        NSLog(@"Updated message: %@", message.messageId);
    } else {
        NSLog(@"Failed to update message: %@", error);
    }
}];
