Swipe to Delete not working

Question

Hi,

The swipe to delete functionality is not working in my table view. I have implemented the commitEditingStyle delegate and the Edit button in the navigation bar. Hence when the user clicks the edit button, the delete and add buttons show up appropriately. However, on swiping, the delete button does not appear and it seems like it doesn't recognise the swipe as a call for the setEditing method.

I then implemented willBeginEditingRowAtIndexPath and didEndEditingRwoAtIndexPath delegates as follows:

-(void)tableView:(UITableView*)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath

{
 NSLog(@"WILL BEGIN EDITING");

 [self.tableView setEditing:YES animated:YES];

}


-(void)tableView:(UITableView*)tableView didEndEditingRwoAtIndexPath:(NSIndexPath *)indexPath

{

[self.tableView setEditing:NO animated:YES];

}

However this does not have any effect either. What could be the possible issue? I have enabled multi-touch for the table view in the IB and each cell has an DetailDisclosureButton accessory.

Answer 1

For swipe-to-delete functionality, you have to implement

 -(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (editingStyle == UITableViewCellEditingStyleDelete)
        ; // Delete.
}

EDIT: I didn't read the question well enough.

I have noticed that to do a swipe drag in the simulator I have to press and pause for a second while it selects the cell, and only then can I swipe right successfully.

Answer 2

did you implement the tableView:editingStyleForRowAtIndexPath: method and have it return UITableViewCellEditingStyleDelete

Answer 3

I was doing the following in the tableView:editingStyleForRowAtIndexPath: delegate method :-

if (self.editing == NO || !indexPath)

{
return UITableViewCellEditingStyleNone;

}

This was supposed to return editing style none if no indexPath was selected. For some reason whenever a swipe action was performed, this particular if condition was getting executed. On commenting the above code snippet, the swipe to delete action worked fine.

Thanks all for your help.
