    <p>First, here is a <a href="http://screencast.com/t/NDViMjYxZGEt" rel="noreferrer">screencapture showing how this looks</a>.</p> <p>Implement UITextFieldDelegate and display a "popup" containing a UIPickerView.</p> <pre><code>- (void)textFieldDidEndEditing:(UITextField *)textField { UIPickerView *picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 244, 320, 270)]; picker.delegate = self; picker.dataSource = self; [self.view addSubview:picker]; [picker release]; } </code></pre> <p>When the keyboard disappears, a picker view is then visible.</p> <p>If you want to take this a bit further, you can animate the UIPickerView "slide in" like the keyboard. </p> <pre><code>- (void)viewDidLoad { //picker exists in the view, but is outside visible range picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 480, 320, 270)]; picker.delegate = self; picker.dataSource = self; [self.view addSubview:picker]; [picker release]; } //animate the picker into view - (void)textFieldDidEndEditing:(UITextField *)textField { [UIView beginAnimations:@"picker" context:nil]; [UIView setAnimationDuration:0.5]; picker.transform = CGAffineTransformMakeTranslation(0,-236); [UIView commitAnimations]; } //animate the picker out of view - (void)textFieldDidBeginEditing:(UITextField *)textField { [UIView beginAnimations:@"picker" context:nil]; [UIView setAnimationDuration:0.5]; picker.transform = CGAffineTransformMakeTranslation(0,236); [UIView commitAnimations]; } //just hide the keyboard in this example - (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return NO; } </code></pre>

    2. COJust as a note, this is the old way to do this. A more 'modern' version would use the inputView property of the textField.

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).
