    <p>I'm using the code below to integrate right/left swipe events to a UIImageView object (called <strong>photo_view</strong>) but it did not work after tests in iphone simulator and device. The methods <strong>handleLeftSwipe</strong> and <strong>handleRightSwipe</strong> below are not even called as logging didn't print anything in the debugger logs as it should. Here is the code:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; UISwipeGestureRecognizer *leftSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleLeftSwipe:)]; leftSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft; leftSwipeRecognizer.numberOfTouchesRequired = 1; [photo_view addGestureRecognizer:leftSwipeRecognizer]; leftSwipeRecognizer.delegate = self; [leftSwipeRecognizer release]; UISwipeGestureRecognizer *rightSwipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleRightSwipe:)]; rightSwipeRecognizer.direction = UISwipeGestureRecognizerDirectionRight; rightSwipeRecognizer.numberOfTouchesRequired = 1; [photo_view addGestureRecognizer:rightSwipeRecognizer]; rightSwipeRecognizer.delegate = self; [rightSwipeRecognizer release]; } - (void)handleLeftSwipe:(UISwipeGestureRecognizer *)recognizer { NSLog(@"handleLeftSwipe called"); } - (void)handleRightSwipe:(UISwipeGestureRecognizer *)recognizer { NSLog(@"handleRightSwipe called"); } </code></pre> <p>Any idea what the reason ?</p> <p>Thx in advance for helping,</p> <p>Stephane</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.
