how to set UITextView height dynamically inside a custom UITableViewCell with autolayout

Question

I have UITableView, every tableViewCell is custom. Inside my customTableViewCell is a UITextView, TextViews frame is pin or same as its superView which is tableViewCell.

How Am I gonna set the UITableViewCell height dynamically that is proportional to the TextViews size which will also depends to content text that I get from internet.

(sample prototype)

// this is how I manipulate every cell height

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    // How do I set the height here, whats the best approach for this. with autolayout BTW
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// I initialize every cell here with my ArrayContainer, nothing much to refer here.
}

1. Follow this answer: Link reference

2. Add a height constraint to your UITextView and create an outlet to your custom cell class.

3. Use sizeThatFits: on UITextView to get the size that fits the content and set this value as a constant of the constraint described in 2. Do this in tableView:heightForRowAtIndexPath:.

One caveat is that if there're many cells (hundreds or thousands) then you may hit performance issues.
