I have customized a UITableViewCell and I want to implement "swipe to delete". But I don't want the default delete button. Instead, I want to do something different. What would be the easiest way to implement this? Are there some methods which get called when the user swipes to delete a cell? Can I prevent then the default delete button from appearing?
Right now I think I must implement my own logic to avoid the default delete button and shrink animations which happen in swipe to delete in the default implementation of UITableViewCell.
Maybe I have to use a UIGestureRecognizer?
If you want to do something completely different, add a UISwipeGestureRecognizer to each tableview cell.
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
UISwipeGestureRecognizer* sgr = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(cellSwiped:)];
[sgr setDirection:UISwipeGestureRecognizerDirectionRight];
[cell addGestureRecognizer:sgr];
[sgr release];
cell.textLabel.text = [NSString stringWithFormat:@"Cell %d", indexPath.row];
// ...
return cell;
}
- (void)cellSwiped:(UIGestureRecognizer *)gestureRecognizer {
if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
UITableViewCell *cell = (UITableViewCell *)gestureRecognizer.view;
NSIndexPath* indexPath = [self.tableView indexPathForCell:cell];
//..
}
}
Here are two methods that can be used to avoid the Delete Button:
- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath
and
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
