Deletion control button on UITableview edit mode is not working - ios

Question

I have implemented UITableview edit mode when a button is clicked but every time it goes to edit mode and I click on the deletion button, nothing happens. I have a view controller with a UITableview on it. I have set my delegate and tableview source as well as all of my editing callbacks. Everything is working (like reordering cells) but whenever I try to delete by pressing the delete control button, the delete button doesn't show up.
I am desperate since it seems like a really simple problem but no matter what I try it doesn't seem to work.
This is how I am implementing edit mode
- (UITableViewCellEditingStyle) tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:
(NSIndexPath *)indexPath {
return UITableViewCellEditingStyleDelete;
}
- (BOOL) tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (void) tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
[favoriteCurrencyValueList removeObjectForKey:[favoriteCurrencyList objectAtIndex:indexPath.row]];
[favoriteCurrencyList removeObjectAtIndex:indexPath.row];
NSUserDefaults *defaultSettings = [NSUserDefaults standardUserDefaults];
[defaultSettings setObject:favoriteCurrencyList forKey:#"FavoriteCurrencies"];
[defaultSettings setObject:favoriteCurrencyValueList forKey:#"PastValues"];
[defaultSettings synchronize];
[self.favoriteCurrencyTable beginUpdates];
[self.favoriteCurrencyTable deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:(UITableViewRowAnimation)UITableViewRowAnimationLeft];
[self.favoriteCurrencyTable endUpdates];
}
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
indexPathSelected = indexPath;
//[self.view endEditing:YES];
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath
{
[self.favoriteCurrencyList exchangeObjectAtIndex:sourceIndexPath.row withObjectAtIndex:destinationIndexPath.row];
[[NSUserDefaults standardUserDefaults] setObject:self.favoriteCurrencyList forKey:#"FavoriteCurrencies"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
This is what sets the edit mode
- (IBAction)editButtonPressed:(UIBarButtonItem *)sender {
if (self.editing && self.favoriteCurrencyTable.editing) {
self.editing = NO;
[self.favoriteCurrencyTable setEditing:NO animated:YES];
[self.editButton setTitle:#"Edit"];
}
else {
self.editing = YES;
[self.favoriteCurrencyTable setEditing:YES animated:YES];
[self.editButton setTitle:#"Done"];
}
}

Answer 1

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
if (([touch.view isKindOfClass:[UIButton class]] && touch.view.tag==<Button_TAG>)) {
// prevent recognizing touches on the slider
return NO;
}
return YES;
}
For tap gestures add the delegate and write the above code.

You need to implement the following method:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source
} else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
}
}

If delete does not work then it is a problem of your table view delegate or datasource methods called.Check these methods should definitely be called
1.tableView:editingStyleForRowAtIndexPath:
2.tableView:titleForDeleteConfirmationButtonForRowAtIndexPath:
3.tableView:shouldIndentWhileEditingRowAtIndexPath:
You try to check if titleforDeleteConfirmationbutton is called at every time you click edit and check how many times it calls and also check if you are giving indent return value as yes in shouldIndentwhileediting method.
check your gesture recognizers.
