    <p>I would like to show an animation with images of an object rotating. I have an <code>NSArray</code> with frames of the object and I would like to display them frame by frame with the property of <code>UIImageView</code> <code>animationImages</code>. </p> <p>The problem is that I would like to control the animation with <code>UISwipeGestureRecognizer</code> (Right and Left). And depending on the speed of the gesture the object should rotate faster or slower. I think is not possible because the gesture it is called just once and not continuously.</p> <p>(NOTE: this is my first question in StackOverflow)</p> <p>Thank you in advance</p> <p>EDIT: I just post my solution. Maybe it can be useful for anybody. I think it's useful.</p> <p><strong>Firstly:</strong> add gesture to the view.</p> <pre><code>self.recognizer = [[UISwipeGestureRecognizer alloc] init]; self.recognizer.cancelsTouchesInView=NO; [self.view addGestureRecognizer:self.recognizer]; </code></pre> <p><strong>Secondly:</strong> in tocuhMoved method I display the frame that I need depending of the direction of the previous touch. It is called by the event of the user.</p> <pre><code>- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ NSInteger image= [self.animationView.animationImages indexOfObject:self.animationView.image]; UITouch *touch = [touches anyObject]; NSLog(@"Touch moved with index:%i", image); if ((positionTouch.x&lt;[touch locationInView:self.animationView].x)) { if (image==24) { self.animationView.image=[self.animationView.animationImages objectAtIndex:0]; } else{ self.animationView.image=[self.animationView.animationImages objectAtIndex:image+1]; } } else if((positionTouch.x&gt;[touch locationInView:self.animationView].x)){ if (image==0) { self.animationView.image=[self.animationView.animationImages objectAtIndex:24]; } else{ self.animationView.image=[self.animationView.animationImages objectAtIndex:image-1]; } } positionTouch= [touch locationInView:self.animationView]; } </code></pre> <p>Don't forget <code>&lt;UIGestureRecognizerDelegate&gt;</code></p> <p>with this method, I fill the array of frames...</p> <pre><code>-(void)addPictures{ NSMutableArray* mArray=[[NSMutableArray alloc]initWithCapacity:25]; for (int i=0; i&lt;25; i++) { [mArray insertObject:[UIImage imageNamed:[NSString stringWithFormat:@"Picture %i.jpg", i+1]] atIndex:i]; } self.animationView.image=[mArray objectAtIndex:0]; self.animationView.animationImages=mArray; [self.view addSubview:self.animationView]; } </code></pre>

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.
