Table view cell background goes white when deleting a cell - iOS - objective-c

Question

I have an iOS app with a UITableView, I have noticed that the cell background colour flashes white when the user selects the Delete button.
In the editActionsForRowAtIndexPath method, I have created two cell buttons: Edit and Delete. The first button's style is set to UITableViewRowActionStyleNormal. however the second button's style is set to UITableViewRowActionStyleDestructive - I have noticed that this issue only occurs when then style is set to destructive. Does anyone know why this is happening?
Here is the method I am using to set the cell action buttons:
-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {
// Create the table view cell edit buttons.
UITableViewRowAction *editButton = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:#"Edit" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
// Edit the selected action.
[self editAction:indexPath];
}];
editButton.backgroundColor = [UIColor blueColor];
UITableViewRowAction *deleteButton = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
// Delete the selected action.
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}];
return #[deleteButton, editButton];
}
The colour of the cell is normal when the user is scrolling, tapping it or when he/she selects the Edit button, but when they select the Delete button, the cell turns white as the deletion animation is occurring.
How can I fix this?

Answer 1

It turns out the issue I am experiencing, is due to an iOS bug. I found a solution here: https://stackoverflow.com/a/46649768/1598906
[[UITableViewCell appearance] setBackgroundColor:[UIColor clearColor]];
The above code is set in the App Delegate, it set the background color to clear, thus removing the white background view.

Before calling the deleteRowsAtIndexPaths method, you need to remove the object from the data source;
Replace this:
UITableViewRowAction *deleteButton = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
// Delete the selected action.
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}];
with something like this:
UITableViewRowAction *deleteButton = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:#"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
// Delete the selected action.
[self deleteObjectAtIndexPath:indexPath];
}];
and the method to delete:
- (void)deleteObjectAtIndexPath:(NSIndexPath *)indexPath {
// remove object from data source. I assume that you have an array dataSource, or change it according with your data source
[self.dataSource removeObjectAtIndex:(indexPath.row)];
[self.tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
