iOS 8 auto-sizing UITableViewCell with UITextView

Question

iOS 8 introduced a way for tableViews to automatically adjust their cell\'s height based on their content (via AutoLayout).

// in viewDidLoad:
tableView.rowHeigh         


        

Answer 1

This is the function I use, which solves the problem of the table view bouncing back after every keystroke.

 - (void)textViewDidChange:(UITextView *)textView {

    CGFloat fixedWidth = textView.frame.size.width;
    CGSize oldSize = textView.frame.size;
    CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
        // Resize cell only when cell's size changes, to prevent bouncing back and forth.
        if (oldSize.height != newSize.height) {
        [UIView setAnimationsEnabled:NO];
        CGRect newFrame = textView.frame;
        newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
        textView.frame = newFrame;
        [self.tableView beginUpdates];
        [self.tableView endUpdates];
        [UIView setAnimationsEnabled:YES];
        }
    }
