CometChatSchedulerBubble is a versatile type of message widget designed to facilitate easy and efficient event scheduling. It offers the following key features: 1. **Event Scheduling:** Users can send a calendar-like invitation, similar to `Calendly`, allowing the recipient to schedule a meeting conveniently. 2. **Flexible event Parameters**: Senders have the flexibility to set allowed event times and define the time intervals between consecutive events. 3. **Customisable Availability Hours**: Message senders can personalise their availability by specifying a range of hours during which meetings can be scheduled. 4. **ICS File Integration**: Seamlessly integrates with ICS files, analysing the data to provide users with available time slots based on their free time. 5. **Developer Configuration**: As a developer, you have the freedom to configure actions triggered upon scheduling button clicks. This ensures that the platform can be tailored to specific needs and workflows. `CometChatSchedulerBubble` aims to streamline the event scheduling process, offering a user-friendly experience for both senders and recipients. With its robust features, it provides a dynamic solution for coordinating and managing meetings efficiently. ## Properties | Properties | Type | Description | | - | - | - | | **message** | SchedulerMessage | An instance of the `SchedulerMessage` class which holds information about the event scheduling availability. | | **style** | SchedulerBubbleStyle | An object of styles for customizing the UI of the meeting bubble. You can override styles for the wrapper, title, goal completion text, schedule button, etc. If a style is not provided, the default style will be used. | | **onScheduleClick** | ((\_ dateTime: String?, \_ message: SchedulerMessage) -> Void) | The provided parameter is responsible for managing the on-click callback functionality. By default, this parameter initiates a call to the specified URL as outlined in the example below | | **timeSlotSelectorStyle** | TimeSlotSelectorStyle | accepts an object of TimeSlotSelectorStyle which is used to customize the appearance of CometChatTimeSlotSelector | ## SchedulerBubbleStyle `SchedulerBubbleStyle` is a class extending `BaseStyle` containing attributes to customize the appearance of the `CometChatSchedulerBubble` component. | Properties | Type | Description | | - | - | - | | **background** | UIColor | used to set the background color | | **borderWidth** | CGFloat | used to set border | | **cornerRadius** | CometChatCornerStyle | used to set border radius | | **borderColor** | UIColor | used to set border color | | **avatarStyle** | AvatarStyle | used to set the style for the avatar in the scheduler bubble | | **messageTintColor** | UIColor | used to set the tint color for overall message. | | **titleFont** | UIFont | used to set the title font | | **lisItemStyle** | ListItemStyle | used to style header View of all the views inside the message bubble | | **dividerTint** | UIColor | used to set tint color for divider in message bubble | | **titleTint** | UIColor | used to set the tint color for messgae title | | **deactivatedTint** | UIColor | used to set tint color when the message in not intractable to the user. | ## Usage CometChatSchedulerBubble allows for a dynamic combination of developer-provided data and data collected from the user's interaction. It provides flexibility for developers to customize the behaviour of the scheduler button and integrate it seamlessly into their application. ```php theme={null} let schedulerMessage = SchedulerMessage() schedulerMessage.duration = 60 schedulerMessage.title = "Meet Dr. Jackob" schedulerMessage.bufferTime = 15 schedulerMessage.avatarURL = "https:__encrypted-tbn0.gstatic.com_images?q=tbn:ANd9GcRdRz0HEBl1wvncmX6rU8wFrRDxt2cvn2Dq9w&usqp=CAU" schedulerMessage.goalCompletionText = "Meeting Scheduled Successfully!!" schedulerMessage.timezoneCode = TimeZone.current.identifier schedulerMessage.dateRangeStart = Int(Date().timeIntervalSince1970) schedulerMessage.dateRangeEnd = Int(Date().addingTimeInterval(30 * 24 * 60 * 60).timeIntervalSince1970) schedulerMessage.receiverUid = "cometchat-uid-1" schedulerMessage.receiverType = .user schedulerMessage.availability = [ "monday": [TimeRange(startTime: "0000", endTime: "1359")], "tuesday": [TimeRange(startTime: "0000", endTime: "1559")], "wednesday ": [TimeRange(startTime: "0000", endTime: "0659")], "thuesday": [TimeRange(startTime: "0000", endTime: "0959")], "friday": [TimeRange(startTime: "0000", endTime: "1059")], ] let clickAction = APIAction() clickAction.url = "https:__abc.com" clickAction.payLoad = ["isPayloadPresent": true] let scheduleElement = ButtonElement(elementType: .button, elementID: "21", clickAction: clickAction, buttonText: "Submit") schedulerMessage.scheduleElement = scheduleElement let schedulerBubble = CometChatSchedulerBubble() .set(style: schedulerBubbleStyle) .set(message: schedulerMessage) schedulerBubble.translatesAutoresizingMaskIntoConstraints = false self.addSubView(schedulerBubble) ``` ### SchedulerBubble Triggered Request to Endpoint After user interaction, the `SchedulerBubble` generates a request to the specified endpoint i.e upon clicking the schedule button. Like in above example scheduler bubble will trigger a POST request to abc.com The request includes the following payload and headers: #### Headers: ```json theme={null} { "accept": "application_json", "content-type": "application_json" } ``` #### Payload: ```json theme={null} { "appID": "XXXX", "region": "XX", "trigger": "ui_message_interacted", "payload": { "key1": "value1" }, "data": { "conversationId": "user1_user_user4", "sender": "user1", "receiver": "user4", "receiverType": "user", "messageCategory": "interactive", "messageType": "scheduler", "messageId": 373, "interactionTimezoneCode": "Asia_Kolkata", "interactedBy": "user4", "interactedElementId": "1", "schedulerData": { "meetStartAt": "2024-02-15T01:00", "duration": 60 } } } ``` | Properties | Description | | - | - | | meetStartAt | time slot selected by user | | duration | duration for the meeting | | `appID` | app id of the application | | `region` | The text message | | `payload` | The type of the receiver- `CometChatReceiverType.user` (user) or `CometChatReceiverType.group` (group) | | conversationId | The type of the message that needs to be sent which in this case can be: `CometChatMessageType.text`\_\_(text) | | sender | `UID` of the message sender | | receiver | `UID` of the user or `GUID` of the group receiving the message | | receiverType | The type of the receiver- `CometChatReceiverType.user` (user) or `CometChatReceiverType.group` (group) | | messageCategory | The category of the message - MessageCategoryConstants.interactive | | messageType | The type of message which is MessageTypeConstants.scheduler | | messageId | The id of the message | | interactionTimezoneCode | The time zone of user's device | | interactedBy | The User id of interacting user | | interactedElementId | The element id of element making the requiest | if header is provided in the action meeting bubble will not add anything to the header while generating the request This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
