Body
Well, this is a bit late but I figured I would give this a shot anyway. This is probably more of a workaround and may be messy code, but it worked for me. I connected a label and a hidden textfield in IB, and I wrote this code using the UITextFieldDelegate delegate. <pre><code>- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (textField == fineHiddenTextField) { NSString *fineText = [textField.text stringByReplacingCharactersInRange:range withString:string]; if ([fineText length] == 0) { NSString *emptyFine = @"0.00"; float fineValue = [emptyFine floatValue]; fineEntryLabel.text = [NSString stringWithFormat:@"%.2f", fineValue]; } else if ([fineText length] == 1) { NSString *firstDec = [NSString stringWithFormat:@"0.0%@", fineText]; float fineValue = [firstDec floatValue]; fineEntryLabel.text = [NSString stringWithFormat:@"%.2f", fineValue]; } else if ([fineText length] == 2) { NSString *secondDec = [NSString stringWithFormat:@"0.%@", fineText]; float fineValue = [secondDec floatValue]; fineEntryLabel.text = [NSString stringWithFormat:@"%.2f", fineValue]; } else { int decimalPlace = [fineText length] - 2; NSString *fineDollarAmt = [fineText substringToIndex:decimalPlace]; NSString *fineCentsAmt = [fineText substringFromIndex:decimalPlace]; NSString *finalFineValue = [NSString stringWithFormat:@"%@.%@", fineDollarAmt, fineCentsAmt]; float fineValue = [finalFineValue floatValue]; fineEntryLabel.text = [NSString stringWithFormat:@"%.2f", fineValue]; } //fineEntryLabel.text = [NSString stringWithFormat:@"%.2f", fineValue]; return YES; } } </code></pre> Not exactly the neatest, but it really got the job done. The initial if statement was just to make sure that this was only happening for this one particular textField (As there are multiple throughout the same page.) This code was intended for the input of money (The amount of a fine paid) and I wanted it to be simple and easy to use. Just set your label to align from the right, and it should. I am a little wired on coffee right now, but I will answer any questions you may have. :)

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.
