Using manual buttons in table view

I am creating a commenting application that displays a number of comments in a table view from an array. Users can like, dislike or flag comments. I have incorporated this in the application, however, whenever a user clicks like, dislike or flag, the first comment is always actioned.

This is the first couple of lines in my cellForRowAtIndexPath:

NSDictionary *myArray = [commentArray objectAtIndex:indexPath.row];
commentID = [myArray objectForKey:@"ID"];

I've tried to send the the commentID as the tag of the button, but I then realised that it was an ID that included many letters, e.g. 7c3769f28c9547f4b6889201a8c13f1e.

Any help would be appreciated. Thanks

Easiest way around this is to set the tag of the button as the indexPath.row of the cell when you create it.

Then in your likeButtonPressed: and other button handler methods you can use the button's tag to get the data from the correct index:

-(void)likeButtonPressed:(id)sender
{
    UIButton *button = sender;
    NSDictionary *commentData = commentArray[button.tag];
    // Do what you want with commentData here...
}

You can use this code:

cellForRowAtIndexPath Code 

btnlike.tag = indexPath.row
[btnlike addTarget:self action:@selector(likeButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

likeButtonPressed Method

-(IBAction)likeButtonPressed:(id)sender{
NSLog(@"Button tag :%d",[sender tag]);
}

I Had implemented the same concept in my app like this way, Create a nsobject class,declare and implement buttons in that,the in your class cell for row method write like this way, cell =(customCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; cell = [[DetailsRoomsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; cell.buttonRoomType1.tag = indexPath.row; [cell.button1 addTarget:self action:@selector(aMethod1:) forControlEvents:UIControlEventTouchDown]; cell.button2.tag = indexPath.row+1; [cell.buttonRoomType2 addTarget:self action:@selector(aMethod2:) forControlEvents:UIControlEventTouchDown];

this will help you.
