    <p>I'm trying to display a custom UIMenuController when a User long presses on a cell in a grouped UITableView. However, I can't seem to get the UIMenuController to display after successfully detecting the long press. Any help is greatly appreciated. </p> <pre><code>MyViewController.h @interface MyViewController : UIViewController &lt;UITableViewDelegate,UITableViewDataSource&gt; UITableView *table; @property (nonatomic, retain) IBOutlet UITableView *table; @end </code></pre> <p>In the cellForRowAtIndexPath I attach my Long Press Gesture Recognizer</p> <pre><code>cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:SectionsTableIdentifier] autorelease]; UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)]; [cell addGestureRecognizer:longPress]; [longPress release]; </code></pre> <p>Here is my handleLongPress action method</p> <pre><code>-(void)handleLongPress:(UIGestureRecognizer *)longPress { if (longPress.state == UIGestureRecognizerStateBegan) { CGPoint pressLocation = [longPress locationInView:self.table]; NSIndexPath *pressedIndexPath = [self.table indexPathForRowAtPoint:pressLocation]; UIMenuItem *first = [[UIMenuItem alloc] initWithTitle:@"Save" action:@selector(saveRecent)]; UIMenuItem *second = [[UIMenuItem alloc] initWithTitle:@"Edit" action:@selector(editQuery)]; UIMenuController *menuController = [UIMenuController sharedMenuController]; menuController.menuItems = [NSArray arrayWithObjects:first,second,nil]; [menuController setTargetRect:longPress.view.frame inView:longPress.view.superview]; [menuController setMenuVisible:YES animated:YES]; [pressedIndexPath release]; } } </code></pre> <p>The Action methods for the Edit and Save just display a UIAlertView. I also implemented the below method to ensure that when the UIMenuController is displayed only Save and Edit options will be present</p> <pre><code>-(BOOL)canPerformAction:(SEL)action withSender:(id)sender { BOOL canPerform = NO; if (action == @selector(saveRecent)) { canPerform = YES; } if (action == @selector(editQuery)) { canPerform = YES; } return canPerform; } </code></pre> <p>I'm also claiming MyViewController to be first responder</p> <pre><code>-(BOOL)canBecomeFirstResponder { return YES; } </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.
