How to prevent UITableView from scrolling to the top when reloading data in Objective-C?
I've encountered a strange issue with Could someone explain I recently switched to I'm working on a personal project and I'm currently working on an iOS app using Objective-C, and I've encountered a frustrating issue with my UITableView..... Whenever I call `reloadData` on my table view, it unexpectedly scrolls back to the top, which disrupts the user experience. My table view is set up with dynamic cell heights, and I am using automatic dimension for estimating row heights. Here's a simplified version of my implementation: ```objective-c self.tableView.estimatedRowHeight = 100; self.tableView.rowHeight = UITableViewAutomaticDimension; [self.tableView reloadData]; ``` I tried wrapping the `reloadData` call in a `dispatch_async` block to see if timing was an issue, but that didn't help at all. I also checked if there was any code that could be causing the content offset to reset, but I couldn't find anything suspicious. To keep the current scroll position, I attempted to save the offset before reloading: ```objective-c CGPoint offset = self.tableView.contentOffset; [self.tableView reloadData]; self.tableView.contentOffset = offset; ``` Though this seemed to work for simple cases, it causes issues when the data source changes, leading to incorrect offsets if the content size is altered. Additionally, I verified that the data source methods are optimized and not causing unnecessary reloads. The table view is populated from a network request, and sometimes the data comes back empty, but I handle that with a check before the reload. However, it seems the issue persists regardless of whether the data is fresh or empty. I would appreciate any advice or solutions to prevent the UITableView from scrolling to the top upon reloading. Is there a better approach or best practice that I might be missing in managing table view updates in Objective-C? I'm currently using Xcode 14.0 and targeting iOS 15.0. I'd really appreciate any guidance on this. What are your experiences with this? Am I approaching this the right way? I'm working on a CLI tool that needs to handle this.
