Delete a channel

Deleting a channel removes the local channel record from the channel list. This does not delete the messages within the channel — only the channel entry is removed.

Delete a single channel

Call delete(completion:) on a channel instance:

Swift

swift

import NexconnChatSDK
guard let channel = DirectChannel(channelId: "targetUserId") else { return }
channel.delete { success, error in
    if success {
        print("Channel deleted.")
    } else {
        print("Failed: \(error?.localizedDescription ?? "unknown error")")
    }
}

Objective-C

Objective C

NCDirectChannel *channel = [[NCDirectChannel alloc] initWithChannelId:@"targetUserId"];

[channel deleteWithCompletion:^(BOOL success, NCError *error) {
    if (success) {
        NSLog(@"Channel deleted.");
    } else {
        NSLog(@"Failed: %@", error);
    }
}];

Delete multiple channels

Call the class method deleteChannels(identifiers:completion:):

Swift

swift

import NexconnChatSDK
let id1 = ChannelIdentifier(channelType: .direct, channelId: "user1")
let id2 = ChannelIdentifier(channelType: .group, channelId: "groupId")
BaseChannel.deleteChannels(identifiers: [id1, id2]) { error in
    if error == nil {
        print("Channels deleted.")
    }
}

Objective-C

Objective C

NCChannelIdentifier *id1 = [[NCChannelIdentifier alloc] initWithChannelType:NCChannelTypeDirect
                                                                   channelId:@"user1"];
NCChannelIdentifier *id2 = [[NCChannelIdentifier alloc] initWithChannelType:NCChannelTypeGroup
                                                                   channelId:@"groupId"];

[NCDirectChannel deleteChannels:@[id1, id2]
                     completion:^(NCError *error) {
    if (error == nil) {
        NSLog(@"Channels deleted.");
    }
}];

Alternatively, build an identifiers array and pass it to deleteChannels:completion::

Swift

swift

import NexconnChatSDK
let id1 = ChannelIdentifier(channelType: .direct, channelId: "user1")
let id2 = ChannelIdentifier(channelType: .direct, channelId: "user2")
BaseChannel.deleteChannels(identifiers: [id1, id2]) { error in
    if error == nil {
        print("Channels deleted.")
    }
}

Objective-C

Objective C

NCChannelIdentifier *id1 = [[NCChannelIdentifier alloc] initWithChannelType:NCChannelTypeDirect
                                                                  channelId:@"user1"];
NCChannelIdentifier *id2 = [[NCChannelIdentifier alloc] initWithChannelType:NCChannelTypeDirect
                                                                  channelId:@"user2"];

[NCBaseChannel deleteChannels:@[id1, id2]
                   completion:^(NCError * _Nullable error) {
    if (error == nil) {
        NSLog(@"Channels deleted.");
    }
}];
