If you use auto layout and support iOS 8, then you are in luck.

In the past, you will need to implement tableView:heightForRowAtIndexPath: and caculate the height of your cell to return. It is a lot of code just to achieve the goal.

Now, it is just these steps:

Step 1. Set rowHeight

tableView.rowHeight = UITableViewAutomaticDimension
// Similarly, you can set for header & footer
tableView.sectionFooterHeight = UITableViewAutomaticDimension

UITableViewAutomaticDimension is a special value (a CGFloat) that tells the cell to auto adjust it’s height.

You may even return it in tableView:heightForRowAtIndexPath:, if you want a mix of auto and fixed height.

Step 2. Set estimatedRowHeight

tableView.estimatedRowHeight = 85.0

You will also need to set the estimatedRowHeight.

If not, it will NOT work.

The estimated height is needed only for the purpose of calculating the scroll bar height.

Step 3. Autolayout for the cells

Set up autolayout constraints as per normal.

Make sure that the content view has the necessary contraints eg. the bottom is pinned to some view
