Set message content

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

To modify a message through the published API surface, use BaseChannel.modifyMessage(params:completion:) (Objective-C selector: +[NCBaseChannel modifyMessageWithParams:completion:]) with ModifyMessageParams (NCModifyMessageParams in Objective-C).

Modify a message

Method signature

Swift

swift

import NexconnChatSDK

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

Objective-C

Objective C

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

Parameters

Parameter	Type	Description
params	NCModifyMessageParams *	Modification 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 modifyMessageWithParams:completion: and does not expose a separate setMessageContent API.
• NCModifyMessageParams 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 = ModifyMessageParams(messageId: "message_id", content: content)

BaseChannel.modifyMessage(params: params) { message, error in
    if let error {
        print("Failed to modify message: \(error.localizedDescription)")
    } else {
        print("Modified message: \(message?.messageId ?? "")")
    }
}

Objective-C

Objective C

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

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