tableview

问题 I'm experiencing bugs with my application when I'm trying to download and set an image async to a cell with dynamic height. Video of the bug: https://youtu.be/nyfjCmc0_Yk I'm clueless: can't understand why it happens. I'm saving the cell heights for preventing jumping issues and stuff, I do even update the height of the cell after setting the image. func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { var post : Post var cell : PostCell post = Posts

问题 I am creating a custom CheckBoxTableView where the selected items are displayed with a CheckBox. If the user attempts to sort the table once items are selected, it appears to mess up.

Unfortunately - my EventFilter seems to fire after the sort was completed. On the TableView constructor, I placed the following code:

问题 I got a class where I receive some collection structure: public class YIFY { private static List<Pelicula> resultados; public static void setResultados(List<Pelicula> resultados) { YIFY.resultados = resultados; } } Later, at another class I associate the contents of such List to a TableView . However I create an FXCollections.observableArrayList() which is set as the bind element to the table. This is how I do it: peliculas = FXCollections.observableArrayList(YIFY.getResultados());

My problem is that if I try to delete a cell in the search bar's table view then I get a coredata exception :
