Not able to set the dynamic height of table view cell?

Question

I am having the problem in setting the dynamic height for my table view cell.I have used the following code to set it, but it's not working in fact now the cell height has even increased.

See this the code I have added in my project:

 override func viewDidLoad() {
super.viewDidLoad()

        tableview.rowHeight = UITableViewAutomaticDimension
        print(tableview.rowHeight)
        tableview.estimatedRowHeight = 120

}

This the screenshot for the constraints of the table view cell contents:

Please have a look at the constraints as well. Thanks in advance :)

May it will help you https://www.raywenderlich.com/129059/self-sizing-table-view-cells — Dharma, Jun 26 '17 at 06:17
@DSDharma I have followed this tutorial as well but didn't helped me out — Samarth Kejriwal, Jun 26 '17 at 06:20
@DSDharma will you please check out the constraints once, may be there must be a problem — Samarth Kejriwal, Jun 26 '17 at 06:22
Make sure height constant should be greater then equal instead of constant — Dharma, Jun 26 '17 at 06:24
@SamarthKejriwal which label should have dynamic height.? indices name right..? — Gokul G, Jun 26 '17 at 06:32
@Gokul no i want that the whole table view cell should have a dynamic height — Samarth Kejriwal, Jun 26 '17 at 06:37
Your constraint probably is wrong, you have to make sure the cell can determine your cell height by pinning the labels to top and bottom, if error show, change their priority — Tj3n, Jun 26 '17 at 07:16
@Tj3n you mean to say that i have to set the bottom and top space for each label wrt to the cell — Samarth Kejriwal, Jun 26 '17 at 07:25
not to the cell, but to each other to form a height for the cell , like if label1 on top of label2, add constraint like cell top-label1-label2-cellbottom, that will form a height for the cell to auto calculate — Tj3n, Jun 26 '17 at 07:26
ok so you mean to say that i have to define the top bottom contraints relative to each other label — Samarth Kejriwal, Jun 26 '17 at 07:30
@Tj3n please help me out with the constraints . i am not getting it right man .i am new to ios development — Samarth Kejriwal, Jun 26 '17 at 07:36
If it show error (because lines = 0), then you have to select 1 of the 2 label, change their content hugging and resistance priority, the error will gone, its also mentioned in the tutorial on first comment — Tj3n, Jun 26 '17 at 07:42
Pin all the labels/other components to top and bottom too and set height for each as height >= somevalue. Also change lines of label to 0. — Mamta, Jun 26 '17 at 07:52
I am not able to set the constraimts properly ..really messed up :( — Samarth Kejriwal, Jun 26 '17 at 08:41

If u have done everything correct and still u r unable the get desired output means the issue will be with constraints.
I have made a simple constraint layout, use this skeleton as reference and re-constraint your cell.
Add (W:20, H:20) to [img].
Make sure you have set number of lines to 0, and all other automatic dimension stuff's.

you havent defined the top and leading constraints ..should i define them as well ? – Samarth Kejriwal Jun 26 '17 at 10:13
just keep it as reference.. the image may have missed some constraint.. try to follow the same – Gokul G Jun 26 '17 at 10:14
wait i am setting the constraints and then i will send u the screen shot .and then check – Samarth Kejriwal Jun 26 '17 at 10:24
the problem is that my indicesname label is covering the whole width when the indices name is too long and so my curr price item is getting hidden,should i set a desired height for it ? – Samarth Kejriwal Jun 26 '17 at 10:29
if width of indices name is your problm.. add a `Horizontal constraint` between `indices` and `price`. change it's relation to `>=` and constant to 10 – Gokul G Jun 26 '17 at 10:32
i had set the width of the indices name as proportional to 0.7 of the width of the content view – Samarth Kejriwal Jun 26 '17 at 10:34

actually when i was setting the proportional height for my image view in the table view cell then my table view cell height was abruplty expanded, is there any other way to handle this . I am having this problem while setting a proptional height for image view , if i set a proportional width to my image view along with an aspect ration then i dont ge this problem – Samarth Kejriwal Jul 03 '17 at 04:51

You may consider using func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat. It's a method in the UITableViewDelegate and you can use it to return a specific height for the rows you want. https://developer.apple.com/documentation/uikit/uitableviewdelegate/1614998-tableview

I know this is a method, but I have to set a dynamic height, i.e. I want to change the height of each row according to my changing content in the table view cell – Samarth Kejriwal Jun 26 '17 at 06:21
There's likely something wrong with your constraints. Check to see that there are no errors, i.e. any red lines. – Mihir Thanekar Jun 26 '17 at 06:25
@MihitThanekar there isn't any red lines i have already checked it – Samarth Kejriwal Jun 26 '17 at 06:27
Great so try the latter link on my post. Summary: 1. Set constraints. You did that. 2. Set lines on the label to 0. 3. Implement the heightForRow and estimatedHeightForRow and return UITableViewAutomaticDimension in both. Did that help? Let us know. – Mihir Thanekar Jun 26 '17 at 06:29
Should i set each label lines as 0 ? – Samarth Kejriwal Jun 26 '17 at 06:37
Yup. That's what the other forum post said. Try it out. – Mihir Thanekar Jun 26 '17 at 06:39
