如何基于单元格文本获取UICollectionViewCell的indexPath？

Question

I pass the cell title label from "collection view A" to "collection view B". So now in collection View B, I have the cell's title label.

In the viewDidAppear method for collection View B, I'd like to use scrollToItemAtIndexPath to scroll to the proper index containing the cell with that title label.

How would I go about doing that?

Answer 1

Collections work like TableViews. Most people have a backing store of data behind their collection or tableview, which is an array with data in the proper order. Thus, when your cellForRowAtIndexPath or cellForItemAtIndexPath call is invoked, you simply stuff in the value from your backing store. If your model is the same as this you would simply search your collection view B backing store array for the label, and make note of what row it is in.
