Answer 1

I have created one demo for your problem, hope will help you.

My idea of solution is using AutoResizingMask of UITextView.

My .h file

#import 

@interface ViewController : UIViewController{
    IBOutlet UITableView *tlbView;
    float height;
}

@end

And my .m file (Includes only required methods)

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.
    height = 44.0;
}

- (void)textViewDidChange:(UITextView *)textView{
    [tlbView beginUpdates];
    height = textView.contentSize.height;
    [tlbView endUpdates];
}

#pragma mark - TableView datasource & delegates
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return 1;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    if (indexPath.row==0) {
        if (height>44.0) {
            return height + 4.0;
        }
    }
    return 44.0;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"CellIdentifier"];

    UITextView *txtView = [[UITextView alloc] initWithFrame:CGRectMake(0.0, 2.0, 320.0, 40.0)];
    [txtView setDelegate:self];
    [txtView setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight]; // It will automatically resize TextView as cell resizes.
    txtView.backgroundColor = [UIColor yellowColor]; // Just because it is my favourite
    [cell.contentView addSubview:txtView];

    return cell;
}

Hope it will help you out.
