    <pre><code>- (IBAction)namePoints:(id)sender { yValuePoints = 180; pointTextBoxCounter = 0; while (numberOfPointsTextBox.text.intValue &gt; currentPointTextBox) { CGRect textFrame = CGRectMake(245, yValuePoints, 60, 30); UITextField *textField = [[UITextField alloc] initWithFrame:textFrame]; [textField setBackgroundColor:[UIColor whiteColor]]; [textField setBorderStyle:UITextBorderStyleRoundedRect]; textField.textAlignment = UITextAlignmentRight; [self.view addSubview:textField]; currentPointTextBox += 1; yValuePoints += 40; if (yValuePoints &gt; mainScrollView.contentSize.height) { [mainScrollView setContentSize:CGSizeMake(320, (yValuePoints + 20))]; } } while (numberOfPointsTextBox.text.intValue &lt; currentPointTextBox) { [self.view.subviews.lastObject removeFromSuperview]; //[[pointsTextFieldsArray objectAtIndex:currentPointTextBox] removeFromSuperview]; currentPointTextBox -= 1; } </code></pre> <p>}</p> <p>This function is called when numberOfPointsTextBox didFinishEditing. CurrentPointTextBox is an int that (hopefully) keeps track of the number of point text boxes currently on the screen (there others such as planes with a similar function). What I would like is when the value of numberOfPointsTextBox is decreased for the extra point text boxes to be removed. What I have been trying to do is use pointsTextFieldsArray to keep track of the index values of the fields that I have created in the self.view.subviews array so that I can just run the commented out line of code, but NSMutableArray's won't accept int values and I can't find a way find to dynamically create NSIntegers. Does anyone know how to do this? Or a better way to do it?</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.
