Questions tagged [reloaddata]

This tag covers reloadData methods on UITableView, UICollectionView and NSTableView in Apple's UIKit and AppKit frameworks. Do not use it outside the context of Apple frameworks.

Initially this was supposed to cover reloadData on UITableView on Objective-C, but by now it has also been used for all kinds of issues regarding reloading data.

Don't do this, let's leave this to UITableView.
