Body
In your textViewDidChange method, call <pre><code>[tableView beginUpdates]; [tableView endUpdates]; </code></pre> This will trigger heightForRowAtIndexPath to recalculate all your cell sizes each time the user types a letter. Then in heightForRowAtIndexPath, you can then calculate the necessary size for your cell. The sizeWithFont method will return the size needed to display the text in a UILabel, which is slightly different than that for a UITextView due to content insets, line spacing, etc. I've used a somewhat hacky solution in the past. If you create a temporary UITextView, set it's text, and use [UIView sizeThatFits:constraintSize] to get the size that will fit all its content within the constraints. (The documentation on this method is a little unclear - take a look at this answer for more info: <a href="https://stackoverflow.com/questions/5828399/question-about-uiviews-sizethatfits">question about UIView's sizeThatFits</a>) <pre><code>UITextView *temp = [UITextView alloc] initWithFrame:someArbitraryFrame]; temp.font = DISPLAY_FONT temp.text = cell.textView.text; //This gets the necessary size to fit the view's content within the specified constraints CGSize correctSize = [self.temp sizeThatFits:CGSizeMake(CONSTRAINT_WIDTH, CONSTRAINT_HEIGHT)]; return correctSize.height </code></pre> In interest of efficiency, you should probably store/lazy-load the temporary textView so that you're not creating a new UITextView for every cell, but rather re-using the same one to calculate height for different text.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
