Protocol

MSStickerBrowserViewDataSource

Implement the MSStickerBrowserViewDataSource protocol to dynamically provide stickers for a browser.

Overview

To load its stickers, the MSStickerBrowserView class performs the following steps:

  1. The browser calls the data source’s numberOfStickers(in:) method to get the number of stickers.

  2. The browser repeatedly calls the data source’s stickerBrowserView(_:stickerAt:) method to load the individual stickers. Initially, the browser requests only enough stickers to fill the screen. The browser requests additional stickers as the user scrolls and new stickers become visible.

Both methods are required. If the sticker collection changes at runtime, call the MSStickerBrowserView class’s reloadData() method to reload the stickers.
