UITableViewAutomaticDimension not working in Xcode 6.3

Question

I updated my Xcode to 6.3 along with Swift 1.2, and I made the transition.

Everything works except dynamic row height for table view. I have those on 3 completely different table views, so it probably isn't something else influencing the bug.

I set all of the table views to:

tableView.rowHeight = UITableViewAutomaticDimension

and all of my xib files are properly constrained.

Any ideas?

Answer 1

I simply added UITableViewAutomaticDimension to estimatedrowforindexpath as well. You can see how it works on the BEAM App (under 'people' category).

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return UITableViewAutomaticDimension;
}

- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return UITableViewAutomaticDimension;
}

Answer 2

Estimated row height needs to be provided.

It is better not to implement estimatedHeightForRowAtIndexPath: unless necessary.

estimatedRowHeight is cheaper provided you can come up with a value

    tableView.rowHeight = UITableViewAutomaticDimension
    tableView.estimatedRowHeight = 30 //Provide any appropriate value
