问题 I'm working on a application containing a UITableView. The only thing which needs to be possible for users, is to reorder the contents of the UITableView. When in editing mode the background color of the tableview cells turns transparent. Is there any way of keeping the original background color of the tableview cell when it's being reordered?

问题 I am fading out cells of my uitableview as they scroll out of view, or fading them in as they scroll into view. The issue I am facing is that if I scroll really fast sometimes the cells that are completely visible remain dimmed. Here is my code below: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { // Fades out top and bottom cells in table view as they leave the screen NSArray *visibleCells = [self.tableView visibleCells]; if (visibleCells != nil && [visibleCells count] != 0) { //

问题 I am working on creating a dynamic list using SwiftUI. Does the SwiftUI List container reuse the cells similar to UITableView ? 回答1: Yes, List is reusing its ListCoreCellHost s exactly like the way UITableView reuses its UITableViewCell s. Reference: Investigating memory usage with Xcode shows that, when the number of the items is more than List could present at once, it just shows as much as it can and reuses them when they become occluded from the top or bottom of the list .
