[Solved] _fetchedResultsController objectAtIndexPath:indexPath freezes app

The alternative way is to use self-sizing cells. You won’t have to calculate (or cache) any row heights.

  1. Add Auto Layout constraints to your tableViewCell’s subviews which will cause the cell to adjust its height based on the subview’s contents.
  2. Enable row height estimation.

    self.tableView.rowHeight = UITableViewAutomaticDimension;
    self.tableView.estimatedRowHeight = 44.0;
