how to tell which image of a set was tapped on in a UITableViewCell

For one of my tableview, there are images in some of cells and there could be more than one images in each of those cells. Now when user tapped on an image, I want to bring up a image viewer to show the full image. But I have a hard time to figure out the best way to know which picture was tapped on. I created them as UIImageView. Any suggestions?

You can use tags as suggested in the other answers or you can use switch case

in the method -

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

switch(indexPath.section) {

    case 0:{
//set the _imagename = @"Something"
break;
}
    case 1:{
//set the _imagename = @"Something else"
break;
}
}

hope this helps

Set tag for each images of cell.

In .h declare 

 NSInteger TagValue ;

In .m ViewDidLoad 

 TagValue = 0;

At CellForRowAtIndexPath : 

TagValue++;

image1.tag = TagValue;

TagValue++;

image2.tag = TagValue;

On selection of it , now you have tag value on that you can get particular selected image.

And to get images form array 

image1.image = [array objectAtIndex:image1.tag];

you will get your respective image.

what you can do is , instead of using UIImageView , use Costume Button and set the Image of That costume button and give all the buttons different tags... each cell will have set of buttons with different tags and by assigning the single selector to all button you can easily determine that which image is clicked.
