# reconfigureRows(at:) Updates the data for the rows at the index paths you specify, preserving the existing cells for the rows. ``` func reconfigureRows(at indexPaths: [IndexPath]) ``` ## Parameters `indexPaths` An array of objects identifying the items you want to update. ## Discussion To update the contents of existing (including prefetched) cells without replacing them with new cells, use this method instead of [`reloadRows(at:with:)`](/documentation/UIKit/UITableView/reloadRows(at:with:)). For optimal performance, choose to reconfigure rows instead of reloading rows unless you have an explicit need to replace the existing cell with a new cell. Your cell provider must dequeue the same type of cell for the provided index path, and must return the same existing cell for a given index path. Because this method reconfigures existing cells, the table view doesn’t call [`prepareForReuse()`](/documentation/UIKit/UITableViewCell/prepareForReuse()) for each cell dequeued. If you need to return a different type of cell for an index path, use [`reloadRows(at:with:)`](/documentation/UIKit/UITableView/reloadRows(at:with:)) instead. If your cells are self-sizing, the table view resizes your cells after reconfiguring them. By default, the table view animates any size or layout changes that are a result of reconfiguration. To reconfigure cells without animation, use `UIView`’s [`performWithoutAnimation(_:)`](/documentation/UIKit/UIView/performWithoutAnimation(_:)) when you call this method. Alternatively, to avoid animations when setting specific properties, use [`performWithoutAnimation(_:)`](/documentation/UIKit/UIView/performWithoutAnimation(_:)) in your cell configuration logic. If your table view uses a custom implementation of `UITableViewDataSource`, use this method. If your table view uses a diffable data source, use [`reconfigureItems(_:)`](/documentation/UIKit/NSDiffableDataSourceSnapshot-swift.struct/reconfigureItems(_:)) (Swift) or [`reconfigureItems(withIdentifiers:)`](/documentation/UIKit/NSDiffableDataSourceSnapshotReference/reconfigureItems(withIdentifiers:)) (Objective-C) on `NSDiffableDataSourceSnapshot` instead. --- Copyright © 2026 Apple Inc.
