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

Primarily get the texts as NSArray and Assign it into the UITextView's as temporary, So that you will get the Height of Cell :

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
        CGRect frame;
        //  set the height here, According to the NSArray of text 
        if(textView || section )
        UITextView *tempTxtView = [[UITextView alloc] init];
        tempTxtView.text = // Add the Text of index according to the Section
        // Fit  the  UITextView to the Content 
        frame = tempTxtView.frame;
        frame.size.height = tempTxtView.contentSize.height;
        tempTxtView.frame = frame;
    }    
    return frame.size.height;
 }

Once got the UITableViewCell height : Then No need to worry about this, right ?

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

self.textView =  [[UItextView alloc] initWithFrame:CGRectMake(cell.frame.origin.x +20, cell.frame.origin.y +10, cell.frame.size.width - 20, cell.frame.size.height - 20)];

// ....... Do further with the NSArray of Text


}

Note : I Haven't Tested, Its just a thought. Hope this will help you

 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
 {
      CGSize titlesize = [TxtValue.text sizeWithFont:[UIFont fontWithName:appdel.strFont size:25.0f] constrainedToSize:CGSizeMake(300, MAXFLOAT) lineBreakMode:NSLineBreakByWordWrapping];  /// ----- -set width as per your requirement inplace of 300 

      return titlesize.height+10;
 }

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{

}

1. Follow this answer: http://stackoverflow.com/a/18746930/1990236

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's many cells (hundreds or thousands) then you may hit performance issues.
