Text Cell

Overview​

LMFeedPostTextCell is a subclass of LMPostWidgetTableViewCell designed to display text-based posts in the LikeMinds Feed module. This cell is responsible for presenting the post’s title and body text. It includes a "See More" button that appears when the content exceeds a certain length. The layout is managed using Auto Layout to ensure proper arrangement and sizing of subviews according to the content.

LMFeedPostTextCell

Protocols​

LMFeedPostTextCellDelegate​

Conforms to LMPostWidgetTableViewCellDelegate. It includes functions for handling interactions within the text cell:

  • didTapPost(postID: String): Invoked when the user taps on the post content.
  • didTapURL(url: URL): Called when a URL in the text is tapped.
  • didTapRoute(route: String): Called when a route in the text is tapped.
  • didTapSeeMoreButton(for postID: String): Called when the "See More" button is tapped.

UI Components​

  • questionTitle: An LMLabel displaying the title of the post.
  • postText: An LMTextView that shows the body text of the post. It supports rich text attributes and handles user interactions such as tapping on URLs or hashtags.
  • seeMoreButton: An LMButton that shows additional content when the post text exceeds a certain length.

Data Variables​

  • actionDelegate: A weak reference to an instance conforming to LMFeedPostTextCellDelegate for handling user interactions.
  • postID: An optional String that stores the identifier of the post.

Methods​

  • configure(data: LMFeedPostContentModel): Configures the cell with the provided post data. Sets the title, body text, and configures the visibility of the "See More" button based on the content length.
  • tappedTextView(tapGesture: UITapGestureRecognizer): Handles taps on the text view. Determines if a URL, hashtag, route, or post content was tapped and notifies the delegate accordingly.
  • didTapURL(url: URL): Called when a URL is tapped in the text view.
  • didTapHashTag(hashtag: String): Placeholder for handling hashtag taps (currently does nothing).
  • didTapRoute(route: String): Called when a route is tapped in the text view.
  • didTapSeeMoreButton(): Called when the "See More" button is tapped. Notifies the delegate to handle the event.

Action Handlers​

  • didTapSeeMoreButton(): The selector method for the "See More" button's tap action. It checks if the postID is set and notifies the delegate to handle the event.

Customisation​

To create a custom cell for LMFeedPostTextCell, follow these steps:

Step 1: Create a Custom Text Cell​

CustomTextCell.swift
class CustomTextCell: LMFeedPostTextCell {
    override func setupAppearance() {
        super.setupAppearance()
        contentView.backgroundColor = .lightGray
        questionTitle.font = UIFont.boldSystemFont(ofSize: 18)
    }
}

Step 2: Replace the Default Cell in the UI Components Class​

In AppDelegate.swift, update the LMUIComponents.shared.textCell to use the custom cell class:

AppDelegate.swift
func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
    LMUIComponents.shared.textCell = CustomTextCell.self
    // ...
    return true
}
