Question

I’ve got a UITableView instance and implemented:

tableView:canEditRowAtIndexPath:
tableView:editingStyleForRowAtIndexPath:
tableView:shouldIndentWhileEditingRowAtIndexPath:
tableView:canMoveRowAtIndexPath:
tableView:moveRowAtIndexPath:toIndexPath:

After that I can see all my cells with reorder controls.

Apple’s header says:

@property(nonatomic) BOOL showsReorderControl; // default is NO

If the default value is NO why am I seeing the reorder controls?

Update:
I’ve also checked the value of property in tableView:cellForRowAtIndexPath: right after when the cell is created:

(lldb) p [c showsReorderControl]
(BOOL) $1 = NO

Answer 1

When you return YES from tableView:canMoveRowAtIndexPath:, it does the same thing as setting the showsReorderControl to YES. These are just two different ways to enable the reorder control.

In fact, there is a third way – let’s never complain that we don’t have options! 😉 From the documentation of tableView:canMoveRowAtIndexPath::

This method allows the delegate to specify that the reordering control
for a the specified row not be shown. By default, the reordering
control is shown if the data source implements the
tableView:moveRowAtIndexPath:toIndexPath: method.
