    <p>I'm trying to implement in my ViewController( which has a tableView) two gesture recognisers that have to work one after another. The first one is a swipe down gesture and the second a long press gesture. </p> <p>Here's my code modified with @sergio suggestions </p> <pre><code> - (void)viewDidLoad { [super viewDidLoad]; swipeDown = [[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeDownAction)] autorelease]; longPress = [[[CustomLongPress alloc]initWithTarget:self action:@selector(longPressAction)] autorelease]; longPress.minimumPressDuration = 2; swipeDown.numberOfTouchesRequired = 1; swipeDown.direction = UISwipeGestureRecognizerDirectionDown; swipeDown.delegate = self ; longPress.delegate = self ; [myTableView addGestureRecognizer:swipeDown]; [myTableView addGestureRecognizer:longPress]; } -(void)swipeDownAction { _methodHasBeenCalled = YES; // bool @property declared in .h NSLog(@"Swipe down detected"); } -(void)longPressAction { NSLog(@"long press detected"); } - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { return YES; } </code></pre> <p>And my UILongPressGestureRecognizer subclass:</p> <pre><code>#import "CustomLongPress.h" #import "ViewController.h" @interface CustomLongPress() { ViewController *vc; } @end @implementation CustomLongPress -(id)initWithTarget:(id)target action:(SEL)action controller:(ViewController *)viewCon { self = [super initWithTarget:target action:action]; if (self) { vc = viewCon; } return self; } -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(vc.methodHasBeenCalled ? @"Yes" : @"No"); if (vc.methodHasBeenCalled) { [super touchesBegan:touches withEvent:event]; } } </code></pre> <p>Unfortunately, I still get only the log from swipeDown but no log when it comes to longPress</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.

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