# Navigate Live Chat UI

You may optionally navigate through TapTalk.io Omnichannel Live Chat's UI, such as case list and chat room, using the following methods:

### Open TapTalk Omnichannel View

To open TapTalk Omnichannel's view UI for your application, you can use the **`presentTapTalkLiveViewWithCurrentNavigationController:animated`** or **`pushTapTalkLiveViewWithCurrentNavigationController:animated`** method from the **TapTalkLive** class. This will open an activity containing a chat room list for your user, and will open a **Create Case Form** activity on top if the user is new or do not have any existing case.

{% tabs %}
{% tab title="Objective-C" %}
{% code title="YourViewController.m" %}

```csharp
#import <TapTalkLive/TapTalkLive.h>

/**
Called to show TapTalk Live view with present animation

 @param navigationController (UINavigationController *) your current navigation controller
 @param animated (BOOL) make the present animated or not
*/
[[TapTalkLive sharedInstance] presentTapTalkLiveViewWithCurrentNavigationController:NAVIGATION_CONTROLLER animated:ANIMATED];

/**
Called to show TapTalk Live view with push animation

 @param navigationController (UINavigationController *) your current navigation controller
 @param animated (BOOL) make the present animated or not
*/
[[TapTalkLive sharedInstance] pushTapTalkLiveViewWithCurrentNavigationController:NAVIGATION_CONTROLLER animated:ANIMATED];

/**
Obtain main view controller of TapTalk Live
*/
[[TapTalkLive sharedInstance] getTapTalkLiveViewMainController];
```

{% endcode %}
{% endtab %}
{% endtabs %}

{% hint style="info" %}
**Parameters**\
\&#xNAN;**`NAVIGATION_CONTROLLER`**: (UINavigationController) your current active navigation controller\
\&#xNAN;**`ANIMATED`**: (BOOL) boolean to state animation active or not
{% endhint %}

### Open Case List View

You can open the user's case list page by calling **`openCaseListView`**. If no user is authenticated, create case form will be opened instead.

{% tabs %}
{% tab title="Objective-C" %}
{% code title="YourViewController.m" %}

```csharp
#import <TapTalkLive/TapTalkLive.h>

[[TapTalkLive sharedInstance] presentCaseListViewWithCurrentNavigationController:NAVIGATION_CONTROLLER animated:ANIMATED];
```

{% endcode %}
{% endtab %}
{% endtabs %}

### Open Existing Case's Chat Room

To use this method, you need to first finish [authentication](/onetalk-omnichannel-documentation/onetalk-channel-integration/live-chat/onetalk-ios/authentication.md#authenticate-user-optional) process.

Once authenticated, you can open a chat room from one the user's case by calling **`openCaseChatRoom`**, providing the **context** and **XC Room ID**. You may obtain XC Room ID from one of the [active user's case list](/onetalk-omnichannel-documentation/onetalk-channel-integration/live-chat/onetalk-ios/case-and-topic.md#get-active-users-case-list), or by [creating a new case](/onetalk-omnichannel-documentation/onetalk-channel-integration/live-chat/onetalk-ios/case-and-topic.md#create-a-new-case).

{% tabs %}
{% tab title="Objective-C" %}
{% code title="YourViewController.m" %}

```csharp
#import <TapTalkLive/TapTalkLive.h>

[[TapTalkLive sharedInstance] openCaseChatRoomWithXCRoomID:XC_ROOM_ID
                                      navigationController:NAVIGATION_CONTROLLER 
                                                  animated:ANIMATED
success:^(NSString *successMessage) {
    // Successfully opened chat room
}
failure:^(NSError *error) {
    
}];
```

{% endcode %}
{% endtab %}
{% endtabs %}

{% hint style="info" %}
**Parameters**\
\&#xNAN;**`XC_ROOM_ID`**: (String) XC Room ID of the user's case, can be obtained from [**`getUserCaseList`**](/onetalk-omnichannel-documentation/onetalk-channel-integration/live-chat/onetalk-android/case-and-topic.md#get-active-users-case-list) or [**`createNewCase`**](/onetalk-omnichannel-documentation/onetalk-channel-integration/live-chat/onetalk-android/case-and-topic.md#create-a-new-case)`(TTLCaseModel.tapTalkXCRoomID)`\
\&#xNAN;**`NAVIGATION_CONTROLLER`**: (UINavigationController) your current active navigation controller\
\&#xNAN;**`ANIMATED`**: (BOOL) boolean to state animation active or not
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.taptalk.io/onetalk-omnichannel-documentation/onetalk-channel-integration/live-chat/onetalk-ios/navigate-live-chat-ui.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
