Code example

[[OIMManager manager] deleteAllMsgFromLocalWithOnSuccess:^(NSString * _Nullable data) {
    // Local messages cleared; reset in-memory message caches and UI

    // Handle clearing failure
}];

Return value

The onSuccess callback confirms that all local message records on the device were deleted.

State changes after the call

1. Local-only operation: This destructive operation removes records from the current device's local database only. Server roaming records remain intact; if the client synchronizes or re-queries history from the server, messages may be restored.
2. No remote events: This method does not dispatch message deletion events to other devices or users. To clear messages across both the server and local storage simultaneously, see Clear all messages.
