How to pass an object when a button is clicked - objective-c

Question

I have a custom tableview cell which has a button. I need to pass the NSIndexPath object of tablview when the button is clicked. I am able to do is assign a tag to a button, receive the tag using sender..but I want to pass the NSIndexPath object...below is the code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"shortCodeCell";
IPadTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"KeywordsCell" owner:nil options:nil];
for (id currentObject in topLevelObjects)
{
if ([currentObject isKindOfClass:[IPadTableViewCell class]])
{
cell = (IPadTableViewCell *)currentObject;
}
}
}
// Delete
[cell.btnDelete addTarget:self action:#selector(onDelete:) forControlEvents:UIControlEventTouchUpInside];
cell.btnDelete.tag=indexPath.row;
return cell;
}
-(void)onDelete:(id)sender
{
UIButton *btn=(UIButton *)sender;
NSLog(#"BtnIndexpath to be deleted:%d",btn.tag);
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
int errorCode = 0;
kd = [items objectAtIndex:btn.tag];
BOOL isDeleteKeyword= [ServerAPI deleteKeywordWithId:kd.keywordId :&errorCode];
dispatch_async (dispatch_get_main_queue (),
^{
if (isDeleteKeyword) {
[items removeObjectAtIndex:btn.tag];
//[tblKeywords deleteRowsAtIndexPaths:[NSArray arrayWithObject:btnIndexPath] withRowAnimation:YES];
[self.tblKeywords reloadData];
}
else return;
});
});
}

Answer 1

You can set the following in "cellForRowAtIndexPath"
cell.tag = indexPath.section;
cell.btnDelete.tag=indexPath.row;
And in "onDelete" you can create indexPath based on tags assigned.
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[sender tag] inSection:[[sender superview] tag]]

Answer 2

// I assume your UITableView called tableView
// Using this way you don't need to use tag
-(void)onDelete:(id)sender
{
UITableViewCell *cell = (UITableViewCell *)[sender superview];
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
}
