    <p>I am working on the iPhone application. I have four textfields in one of the view. In these four textfield I have one textfield in which there will be use of numberpad keyboard. But on numberpad keyboard there is no return key. So I have added "Done"button programmatically by using following code. </p> <pre><code> if ([[[UIDevice currentDevice] systemVersion] floatValue] &gt;= 3.2) { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil]; } else { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; } - (void)addButtonToKeyboard { // create custom button UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom]; doneButton.frame = CGRectMake(0, 163, 106, 53); doneButton.adjustsImageWhenHighlighted = NO; if ([[[UIDevice currentDevice] systemVersion] floatValue] &gt;= 3.0) { [doneButton setImage:[UIImage imageNamed:@"DoneUp3.png"] forState:UIControlStateNormal]; [doneButton setImage:[UIImage imageNamed:@"DoneDown3.png"] forState:UIControlStateHighlighted]; } else { [doneButton setImage:[UIImage imageNamed:@"DoneUp.png"] forState:UIControlStateNormal]; [doneButton setImage:[UIImage imageNamed:@"DoneDown.png"] forState:UIControlStateHighlighted]; } [doneButton addTarget:self action:@selector(doneButton:) forControlEvents:UIControlEventTouchUpInside]; // locate keyboard view UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1]; UIView* keyboard; for(int i=0; i&lt;[tempWindow.subviews count]; i++) { keyboard = [tempWindow.subviews objectAtIndex:i]; // keyboard found, add the button if ([[[UIDevice currentDevice] systemVersion] floatValue] &gt;= 3.2) { if([[keyboard description] hasPrefix:@"&lt;UIPeripheralHost"] == YES) [keyboard addSubview:doneButton]; } else { if([[keyboard description] hasPrefix:@"&lt;UIKeyboard"] == YES) [keyboard addSubview:doneButton]; } } } - (void)keyboardWillShow:(NSNotification *)note { // if clause is just an additional precaution, you could also dismiss it if ([[[UIDevice currentDevice] systemVersion] floatValue] &lt; 3.2) { [self addButtonToKeyboard]; } } - (void)keyboardDidShow:(NSNotification *)note { // if clause is just an additional precaution, you could also dismiss it if ([[[UIDevice currentDevice] systemVersion] floatValue] &gt;= 3.2) { [self addButtonToKeyboard]; } } - (void)doneButton:(id)sender { NSLog(@"doneButton"); NSLog(@"Input: %@", contactno.text); [contactno resignFirstResponder]; } </code></pre> <p>It is fine for this particular textfield. But this button is also get add for the rest of the textfields. How could unhide this button for other textfields. <img src="https://i.stack.imgur.com/FNOXK.png" alt="enter image description here"></p> <p>thanks alot in advance.</p>

    2. COthis is a really terrible thing to be doing. It can easily break if the implementation of the keyboard ever changes. It doesn't work on iPads, and it especially doesn't work with the split keyboard in iOS 5.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
