Body
Here you go. I would make it into a category for NSString though. <pre><code>- (NSString*)deleteCharacterAtPosition:(int)position inString:(NSString*)myString { NSMutableString *mutableString = [myString mutableCopy]; [mutableString deleteCharactersInRange:NSMakeRange(position, 1)]; return mutableString; } </code></pre> If you don't want to delete any digits. Then, you should check to see if that position has a non-digit character before calling this function. Or you can do this: <pre><code>- (NSString*)deleteCharacterAtPosition:(int)position inString:(NSString*)myString { NSRange range; range.location = position; range.length = 1; return [test stringByReplacingCharactersInRange:range withString:@""]; } </code></pre> This is how to check to see if the position is a digit: <pre><code>- (bool)isCharacterAtPositionADigit:(int)position inString:(NSString*)myString { unichar c = [myString characterAtIndex:position]; NSCharacterSet *numericSet = [NSCharacterSet decimalDigitCharacterSet]; if ([numericSet characterIsMember:c]) { return true; } return false; } </code></pre> Now here is what you want: <pre><code>- (IBAction)clearTextKeyPressed:(id)sender { NSString *enteredText = [NSString stringWithFormat:@"%@", self.targetTextField.text]; int positionToDelete = 3; if ( [enteredText length] > 0 && [enteredText length] >= positionToDelete) { if (![self isCharacterAtPositionADigit:positionToDelete inString:enteredText]) return; NSString* finalText = [self deleteCharacterAtPosition:positionToDelete inString:enteredText]; self.targetTextField.text = finalText; [self.numericGridKeypadDelegate textFieldDidChange:self.targetTextField]; } } </code></pre>

Guidance

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.
