    <p>I read many post here about this topic, but I wasn't able to find an answer to my question, so, hope you won't be bored about another UIKeyboard post :-) </p> <p>In my view controller's implementation I added <code>self</code> as an observer for the two notifications <code>UIKeyboardWillShowNotification</code> and <code>UIKeyboardWillHideNotification</code>, passing the selectors <code>keyboardWillShow:</code> and <code>keyboardWillHide:</code> to handle to notifications. As I touch a <code>UITextField</code>, the <code>keyboardWillShow:</code> method is called but when I press a "Done" button (which dismisses the keyboard) the <code>keyboardWillHide:</code> method is not called. </p> <p>Really, I'd like to make my <code>UITextField</code> show a keyboard with the "hide button" on the bottom right of the keyboard, but I wasn't able to find the right keyboard type. Maybe I need to set the textfield retuntype to "...Done". In that way I saw that "return" key turns to "done". </p> <p>So I set a toolbar to be my <code>UITextField</code>'s <code>inputAccessoryView</code>, so now I can show a standard keyboard with a tool bar above with the "Done" button. As a user touches that button, I hide the keyboard with the <code>resignFirstResponder</code> method. </p> <p>The strange thing is that when I call <code>resignFirstResponder</code>, the <code>UIKeyboardWillHideNotification</code> isn't posted; at least the <code>keyboardWillHide:</code> method is not called.</p> <p>What do you suggest to me? I really wanted to display a keyboard with the small button with the down arrow to hide the keyboard, but also this solution could be right, but I'd like to resize the view and to do this I need to observer <code>UIKeyboardWillHideNotification</code>.</p> <p>Thank you very much for help... </p> <p>(ADDED:) </p> <p>In <code>viewDidLoad</code>:</p> <pre><code>[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:[[self view] window]]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:[[self view] window]]; </code></pre> <p>I took these declarations from one of "yours" post :-) But the willShow works... </p> <p>The action of the "Done" button that's in the <code>UIToolbar</code> that's assigned to be the <code>inputAccessoryView</code> of my text field is:</p> <pre><code>-(void)keyboardDone { [msgTextField resignFirstResponder]; </code></pre> <p>CLOSED: OK! When a developer is stupid... it is stupid :-) :-) </p> <p>This is my corrected willHide method:</p> <pre><code>-(void)keyboardWillHide:(NSNotification*)n { NSDictionary* userInfo; CGSize keyboardSize; CGRect viewFrame; /* This was the bad guy :) I forgot to delete it * after I previously copied the willShow method that * checks if keyboard is already shown (if so returns). * * if( keyboardIsShown ) * return; */ userInfo = [n userInfo]; keyboardSize = [[userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size; viewFrame = [[self scrollView] frame]; viewFrame.size.height += ( keyboardSize.height - TABBAR_HEIGHT ); [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:0.5]; [[self scrollView] setFrame:viewFrame]; [UIView commitAnimations]; keyboardIsShown = NO; NSLog(@"HIDE\n"); } </code></pre> <p>First of all I'd like to thank you all for this useless work in helping me. I'd like to give you some points, so I'll try to rise a "interest point" for each answer, but I need to choose the right one... hard part... :-) </p> <p>Excuse me again... I really didn't see the if() statement... </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.
