Body
You can directly handle keyboard events every-time a user presses a key : In case of UITextField <pre><code>- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { // Do something here... } </code></pre> In Case of UITextView : <pre><code>- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { // Do something here... } </code></pre> So every-time one of these method is called for each key you press using keyboard. You can use NSNotificationCenter also. You only need do add any of these in ViewDidLoad method. <pre><code>NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter]; </code></pre> UITextField : <pre><code>[notificationCenter addObserver:self selector:@selector(textFieldText:) name:UITextFieldTextDidChangeNotification object:yourtextfield]; </code></pre> Then you can put your code in method <code>textFieldText:</code>: <pre><code>- (void)textFieldText:(id)notification { // Do something here... } </code></pre> UITextView <pre><code>[notificationCenter addObserver:self selector:@selector(textViewText:) name:UITextViewTextDidChangeNotification object:yourtextView]; </code></pre> Then you can put your code in method <code>textViewText:</code>: <pre><code>- (void)textViewText:(id)notification { // Do something here... } </code></pre> Hope it helps .

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.
