Question

i have a UITableView and i am showing different images in cells,each image has different height,how can i customize the cell height with respect to heights of images ?

Answer 1

Implement the UITableViewDelegate method – tableView:heightForRowAtIndexPath:. See the documentation.

For example, if you’re using Interface Builder, right-button-drag from your table view to the controller itself, add <UITableViewDelegate> after UIViewController in your view controller’s class declaration, and add something like this to the the class .m file:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
  UIImage *image = imagesArray[indexPath.row];
  return image.size.height + 5; // 5 = margin.
}
