notifyItemInserted

NotifyItemInserted is a property of the UICollectionView in iOS and macOS. It is a block that can be used to notify the app that an item has been inserted into the collection view. This property is used in conjunction with the insertItemsAtIndexPaths method, which inserts one or more items into the collection view.

When an item is inserted into the collection view, the UICollectionView will call the NotifyItemInserted block with the NSIndexPath of the inserted item, the public display name of the item, and the inserted location as parameters. This allows the app to perform any necessary actions in response to the insertion, such as updating a data model or displaying a notification to the user.

NotifyItemInserted is a useful property when the collection view is being populated with data that needs to be kept up-to-date with changes to the underlying data model. By using this property, the app can ensure that it is always aware of the current state of the collection view and can respond accordingly.

The NotifyItemInserted block is passed to the insertItemsAtIndexPaths method when calling to insert one or more items into the collection view. This block can be used to monitor the insertion and take any necessary actions to ensure that the collection view accurately reflects the state of the underlying data model.

In summary, NotifyItemInserted is a useful property that provides a way for the app to be notified when an item is inserted into the collection view, allowing the app to update its own state to accurately reflect the current state of the collection view.
