Typing Indicators

Send a Typing Indicator

In other words, as a sender, how do I let the recipient(s) know that I'm typing?

Start Typing

You can use the startTyping() method to inform the receiver that the logged-in user has started typing. The receiver will receive this information in the onTypingStarted() method of the CometChatMessageDelegate protocol conformance. In order to send the typing indicator, you need to use the TypingIndicator class.

Swift

let typingIndicator = TypingIndicator(receiverID: "receiverUID", receiverType: .user)

CometChat.startTyping(indicator: typingIndicator)

Objective C

TypingIndicator *typingIndicator = [[TypingIndicator alloc]initWithReceiverID:@"receiverID" receiverType: ReceiverTypeUser metadata:nil];

[CometChat startTypingWithIndicator:typingIndicator];

Stop Typing

You can use the endTyping() method to inform the receiver that the logged-in user has stopped typing. The receiver will receive this information in the onTypingEnded() method of the CometChatMessageDelegate protocol conformance. In order to send the typing indicator, you need to use the TypingIndicator class.

Swift

let typingIndicator = TypingIndicator(receiverID: "receiverUID", receiverType: .user)

CometChat.endTyping(indicator: typingIndicator)

Objective C

TypingIndicator *typingIndicator = [[TypingIndicator alloc]initWithReceiverID:@"receiverID" receiverType: ReceiverTypeUser metadata:nil];

[CometChat endTypingWithIndicator:typingIndicator];

Custom Data

You can use the metaData field of the TypingIndicator class to pass additional data along with the typing indicators. A metaData field is a dictionary and this property can be set from TypingIndicator class. This data will be received at the receiver end and can be obtained using the metaData property.

Real-time Typing Indicators

In other words, as a recipient, how do I know when someone is typing?

You will receive the typing indicators in the onTypingStarted() and the onTypingEnded() method of the CometChatMessageDelegate. In order to receive typing indicators, you must add protocol conformance CometChatMessageDelegate.

Swift

extension ViewController: CometChatMessageDelegate {

  func onTypingStarted(_ typingDetails : TypingIndicator) {

    print("Typing started received successfully")
  }

  func onTypingEnded(_ typingDetails : TypingIndicator) {

    print("Typing ended received successfully")
  }
}

Objective C

@interface ViewController ()<CometChatMessageDelegate>

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    CometChat.messagedelegate = self ;
}

- (void)onTypingStarted:(TypingIndicator *)typingDetails {
    NSLog(@"Typing started received successfully");
}

- (void)onTypingEnded:(TypingIndicator *)typingDetails {
    NSLog(@"Typing ended received successfully");
}

@end

The TypingIndicator class consists of the below parameters:

Parameter	Information
sender	An object of the User class holding all the information. related to the sender of the typing indicator.
receiverId	unique Id of the receiver. This can be the Id of the group or the user the typing indicator is sent to.
receiverType	This parameter indicates if the typing indicator is to be sent to a user or a group. The possible values are: 1. CometChat.ReceiverType.user 2. CometChat.ReceiverType.group
metaData	A Dictionary to provide additional data
