目标C-滑动以删除行

Question

I'm new to objective-c and gotten some legacy code for adding new features. My app needs that rows from a table are deleted by swiping then out . The implementation already support the ordering of rows .

I have already read previous questions UITableViewCell, show delete button on swipe and using swipe gesture to delete row on tableview . I don't want to show any button for deleting rows ( nor the (-) (red left button) neither the DELETE button that is displayed on the right when clicking the (-) red left button ).

I have already defined the following methods:

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"editingStyleForRowAtIndexPath");
    return UITableViewCellEditingStyleNone;
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"canEditRowAtIndexPath");
    return YES; // allow that row to swipe
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"commitEditingStyle");
}

The behavior is that with this "configuration" the delete left red button is displayed . When it is clicked, it displays a DELETE button on the right of the row . Clicking on it run the commitEditingStyle delegate .

Removing the tableView:editingStyleForRowAtIndexPath make disappear the left red button and swipe does not work. Nor I manage to get execution in the commitEditingStyle delegate.

Any suggestion or ideas why the commitEditingStyle delegate is not invoked?

Answer 1

Just write code for deleting row in to - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath

I have checked and this works fine for me.

This will delete row on swipe without showing delete button. I hope this will solve your problem.

replace

return UITableViewCellEditingStyleNone 

with

return UITableViewCellEditingStyleDelete
