    <p>I have an UIScrollView with full screen size (iPad, 1024x768, landscape mode). So I need to recognize swipe with two finger in any direction over it. That's what i have (mainScroll is the property of my class):</p> <pre><code>//MyViewController.h - (void)loadView { mainScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)]; mainScroll.contentSize = CGSizeMake(1024*pageNumber, 768); mainScroll.pagingEnabled = YES; mainScroll.delegate = self; [self.view addSubview:mainScroll]; GestureRecognizer *tapInterceptor = [[GestureRecognizer alloc] init]; tapInterceptor.numberOfTouchesRequired = 2; tapInterceptor.direction = UISwipeGestureRecognizerDirectionUp | UISwipeGestureRecognizerDirectionDown | UISwipeGestureRecognizerDirectionLeft | UISwipeGestureRecognizerDirectionRight; [mainScroll addGestureRecognizer:tapInterceptor]; mainScroll.userInteractionEnabled = YES; } </code></pre> <p>and</p> <pre><code>//GestureRecognizer.h - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { if ([touches count] &gt; 1) NSLog(@"Started"); } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { if ([touches count] &gt; 1) NSLog(@"Moved"); } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { if ([touches count] &gt; 1) NSLog(@"Ended"); } </code></pre> <p>I had to add condition</p> <pre><code>if ([touches count] &gt; 1) </code></pre> <p>because it works not only for two (ore more) touches, but also for one.</p> <p>But swipe (with two touches) is still scrolls my UIScrollView. How can i prevent it? So how can I recognize swipe without any effect on my scrollView?</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).
