    <h2>Update, fixed in 7.1. No longer necessary.</h2> <hr> <p>For whatever reason, the animation curve reported on keyboard dismissal is incorrect. It seems to actually be 6 &lt;&lt; 16 instead of 7 &lt;&lt; 17.</p> <p>Here's what I do with <code>UIKeyboardWillChangeFrameNotification</code> to determine which animation curve to use.</p> <pre><code>NSDictionary *keyboardAnimationDetail = [notification userInfo]; CGRect keyboardEndFrameWindow = [keyboardAnimationDetail[UIKeyboardFrameEndUserInfoKey] CGRectValue]; double keyboardTransitionDuration = [keyboardAnimationDetail[UIKeyboardAnimationDurationUserInfoKey] doubleValue]; // gives incorrect value of 7 on dismissal // UIViewAnimationCurve keyboardTransitionAnimationCurve = [keyboardAnimationDetail[UIKeyboardAnimationCurveUserInfoKey] integerValue]; CGRect keyboardEndFrameView = [self.view convertRect:keyboardEndFrameWindow fromView:nil]; CGFloat newConstant = (self.view.frame.size.height - keyboardEndFrameView.origin.y); [UIView animateWithDuration:keyboardTransitionDuration delay:0.0f options:newConstant == 0 ? (6 &lt;&lt; 16) : (7 &lt;&lt; 16) animations:^{ self.tableView.contentInset = UIEdgeInsetsMake(self.tableView.contentInset.top, 0, self.view.frame.size.height - keyboardEndFrameView.origin.y + self.commentToolbar.frame.size.height, 0); self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(self.tableView.scrollIndicatorInsets.top, 0, self.view.frame.size.height - keyboardEndFrameView.origin.y + self.commentToolbar.frame.size.height, 0); self.commentViewToSuperviewBottomConstraint.constant = (self.view.frame.size.height - keyboardEndFrameView.origin.y); [self.view layoutIfNeeded]; } completion:^(__unused BOOL finished){ }]; </code></pre> <p>Basically I determine if the keyboard frame is hiding by seeing if the new y origin will be just outside our view's frame (<code>newConstant</code>). Then based on that I use either 6 or 7:</p> <p><code>newConstant == 0 ? (6 &lt;&lt; 16) : (7 &lt;&lt; 16)</code></p> <p>The rest is just adjusting my <code>tableView</code> <code>contentInset</code> and <code>scrollIndicatorInsets</code>, as well as changing the constant on the toolbar that is moving with the keyboard.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
