How to create static cells with dynamic cell heigh

Question

I have looked at several tutorials that show how to set dynamic cell heights, but all of them only show it if you are using dynamic cells by setting the appropriate constraints and using UITableViewAutomaticDimension. However, I would like to do this for static cells.

I have a table view controller in my app that contains several cells that display a category with a disclosure indicator in which there is a title and then a description and the size of the description text varies. Thus, I would like the height of the cell to be dynamic per the size of the description text.

The reason why I am using static cells and not dynamic cells is because above the category cells I have a few cells with some designs that I could only get by using static cells and storyboarding.

I am using iOS9, Xcode 7.3 and Swift 2.2

UPDATE

Table View Controller Code

import UIKit

class CategoriesTableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.rowHeight = UITableViewAutomaticDimension
        tableView.estimatedRowHeight = 140
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    // MARK: - Table view data source

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 1
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
        return 2
    }

}

UPDATE 2

Per accepted answer below I added the two methods below to my table view controller and removed the 2 lines I had in viewDidLoad(). This did it for me! Keep in mind that I had to make sure all the labels in each cell used a top, bottom, leading and trailing constraint. Also, the number of lines for each label must be set to 0.

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

override func tableView(tableView: UITableView, estimatedHeightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

Answer 1

All you have to do is set proper AutoLayout inside the cell, so the height increases based on the length of the description text. Then you need to set the following in your viewDidLoad

tableview.rowHeight = UITableViewAutomaticDimension
tableview.estimatedRowHeight = 44

Please note: you need to set the numberOfLines of UILabel to 0

Answer 2

You are using text view of each cells. Okay, let's select your text view and uncheck the scrolling enabled like as below image.

Add the below code to your view controller:

 func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
   return UITableViewAutomaticDimension
 }

 func tableView(tableView: UITableView, estimatedHeightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
   return UITableViewAutomaticDimension
 }

For Swift 3

 override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
   return UITableViewAutomaticDimension
 }

 override func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
   return UITableViewAutomaticDimension
 }

@Forge, add please to your topic
Swift 4 variant:

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

override func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}
