iphone - Get the indexpath of the selected cell -

when user taps on default delete button in uitableview edit mode,the user should alertview , if hits delete again in alertview row should deleted.initially have done following code without alertview , worked fine.

  [[self categoriesarray]removeobjectatindex:[indexpath row]];    nsarray *indexpathstoremove = [nsarray arraywithobject:indexpath];    [self.tableview deleterowsatindexpaths:indexpathstoremove withrowanimation:uitableviewrowanimationleft];    [self.categoriesarray writetofile:[self datafilepath]  atomically:yes]; 

but now,as have use same code in alertview delegate method.i dont know how [indexpath row]

set indexpath uialertview tag , delegate.

- (void)tableview:(uitableview *)tableview commiteditingstyle:(uitableviewcelleditingstyle)editingstyle forrowatindexpath:(nsindexpath *)indexpath // indexpath here {     if (editingstyle == uitableviewcelleditingstyledelete)     {        uialertview * alertview = [[uialertview alloc]initwithtitle:@"alert" message:@"are sure want delete" delegate:self cancelbuttontitle:@"cancel" otherbuttontitles:@"delete", nil];        [alertview settag:indexpath.row]; // assigning here.
