    <p>I'm currently working on an iPhone application with a single view, which has multiple UITextFields for input. When the keyboard shows, it overlays the bottom textfields. So I added the corresponding <code>textFieldDidBeginEditing:</code> method, to move the view up, which works great:</p> <pre><code>- (void)textFieldDidBeginEditing:(UITextField *)textField { if ( ( textField != inputAmount ) &amp;&amp; ( textField != inputAge ) ) { NSTimeInterval animationDuration = 0.300000011920929; CGRect frame = self.view.frame; frame.origin.y -= kOFFSET_FOR_KEYBOARD; frame.size.height += kOFFSET_FOR_KEYBOARD; [UIView beginAnimations:@"ResizeForKeyboard" context:nil]; [UIView setAnimationDuration:animationDuration]; self.view.frame = frame; [UIView commitAnimations]; } } </code></pre> <p>This method checks, if the source of the message is one of the textfields that are visible when the keyboard shows, and if not, it moves the view up.</p> <p>I also added the <code>textFieldDidEndEnditing:</code> method, which moves the view down again (and updates some model objects according to the changed input):</p> <pre><code>- (void)textFieldDidEndEditing:(UITextField *)textField { if ( ( textField != inputMenge ) &amp;&amp; ( textField != inputAlter ) ) { NSTimeInterval animationDuration = 0.300000011920929; CGRect frame = self.view.frame; frame.origin.y += kOFFSET_FOR_KEYBOARD; frame.size.height -= kOFFSET_FOR_KEYBOARD; [UIView beginAnimations:@"ResizeForKeyboard" context:nil]; [UIView setAnimationDuration:animationDuration]; self.view.frame = frame; [UIView commitAnimations]; } // Additional Code } </code></pre> <p>However, this solution has a simple flaw: When I finish editing one of the "hidden" textfields and touch another textfield, the keyboard vanishes, the view moves down, the view moves up again and the keyboard reappears.</p> <p>Is there any possibility to keep the keyboard from vanishing and reappearing between two edits (of the "hidden" textfields - so that the view only moves when the selected textfield changes from one that would be hidden by the keyboard to one that would not be hidden)?</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.
