UITableViewCell reorder control disappearing when table is scrolled

Question

My UITableView has 2 custom cells: cell1 & cell2

My UITableView displays one or the other depending on an enum value.

If enumValue == 0, cell1 is shown and the table should not allow reordering if enumValue > 0, cell2 is shown and the table should allow reordering

All that is working fine. The reorder controls are displayed appropriately as the enum values change.

My problem: When the reorder controls appear on the cell, they will disappear when the row is scrolled out of view. Why is this happening?

Sorry about the formatting and rough code. I was haven't issues with the site. Anything obvious stand out that could be causing this?

Answer 1

This is iOS 8 bug. A simple workaround is to override prepareForReuse in the UITableViewCell subclass like this:

- (void)prepareForReuse
{
    [super prepareForReuse];
    [self setEditing:NO animated:NO];
}

Answer 2

I had the same issue in a Table View where I had reorderable cells dans not reorderable cell. I tried some solutions (different reusable identifiers, ...) the solution I found was to set the property showsReorderControl to YES in my setter.

self.showsReorderControl = reorderable;
[self setEditing:reorderable animated:NO];

Hope that helps
