UITableView flickers/stutters while entering text in auto resizing TextView

Just disable animation before calling beginUpdates and re-enable it after calling endUpdates.

[UIView setAnimationsEnabled:NO];
[tableView beginUpdates];
[tableView endUpdates];
[UIView setAnimationsEnabled:YES];

Definitely a hack but works for now. Credit to my friend Beau who pointed me to this.

My solution (for iOS 8) was first set in my viewController viewDidLoad

self.tableView.rowHeight = UITableViewAutomaticDimension;
// this line is needed to cell`s textview change cause resize the tableview`s cell
self.tableView.estimatedRowHeight = 50.0;

then, combining this article solution in Swift and some dirty thoughts I`ve set in my cell a property, called

@property (nonatomic, strong) UITableView *hostTableView;

and in cell-s -(void) textViewDidChange:(UITextView *)textView

 CGFloat currentTextViewHeight = _textContainer.bounds.size.height;
CGFloat toConstant = ceilf([_textContainer sizeThatFits:CGSizeMake(_textContainer.frame.size.width, FLT_MAX)].height);
if (toConstant  >  currentTextViewHeight)
{
    [_hostTableView beginUpdates];
    [_hostTableView endUpdates];
}

then in viewController

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

textCell.hostTableView = self.tableView;
