    <p>To expand upon what Nikolai said, the best way to handle this is to use Core Animation to animate the motion of the image or view along a Bezier path. This is accomplished using a CAKeyframeAnimation. For example, I've used the following code to animate an image of a view into an icon to indicate saving (as can be seen in the <a href="http://www.sunsetlakesoftware.com/picubed" rel="noreferrer">video for this application</a>):</p> <p>First of all import QuartzCore header file <code>#import &lt;QuartzCore/QuartzCore.h&gt;</code></p> <pre><code>UIImageView *imageViewForAnimation = [[UIImageView alloc] initWithImage:imageToAnimate]; imageViewForAnimation.alpha = 1.0f; CGRect imageFrame = imageViewForAnimation.frame; //Your image frame.origin from where the animation need to get start CGPoint viewOrigin = imageViewForAnimation.frame.origin; viewOrigin.y = viewOrigin.y + imageFrame.size.height / 2.0f; viewOrigin.x = viewOrigin.x + imageFrame.size.width / 2.0f; imageViewForAnimation.frame = imageFrame; imageViewForAnimation.layer.position = viewOrigin; [self.view addSubview:imageViewForAnimation]; // Set up fade out effect CABasicAnimation *fadeOutAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"]; [fadeOutAnimation setToValue:[NSNumber numberWithFloat:0.3]]; fadeOutAnimation.fillMode = kCAFillModeForwards; fadeOutAnimation.removedOnCompletion = NO; // Set up scaling CABasicAnimation *resizeAnimation = [CABasicAnimation animationWithKeyPath:@"bounds.size"]; [resizeAnimation setToValue:[NSValue valueWithCGSize:CGSizeMake(40.0f, imageFrame.size.height * (40.0f / imageFrame.size.width))]]; resizeAnimation.fillMode = kCAFillModeForwards; resizeAnimation.removedOnCompletion = NO; // Set up path movement CAKeyframeAnimation *pathAnimation = [CAKeyframeAnimation animationWithKeyPath:@"position"]; pathAnimation.calculationMode = kCAAnimationPaced; pathAnimation.fillMode = kCAFillModeForwards; pathAnimation.removedOnCompletion = NO; //Setting Endpoint of the animation CGPoint endPoint = CGPointMake(480.0f - 30.0f, 40.0f); //to end animation in last tab use //CGPoint endPoint = CGPointMake( 320-40.0f, 480.0f); CGMutablePathRef curvedPath = CGPathCreateMutable(); CGPathMoveToPoint(curvedPath, NULL, viewOrigin.x, viewOrigin.y); CGPathAddCurveToPoint(curvedPath, NULL, endPoint.x, viewOrigin.y, endPoint.x, viewOrigin.y, endPoint.x, endPoint.y); pathAnimation.path = curvedPath; CGPathRelease(curvedPath); CAAnimationGroup *group = [CAAnimationGroup animation]; group.fillMode = kCAFillModeForwards; group.removedOnCompletion = NO; [group setAnimations:[NSArray arrayWithObjects:fadeOutAnimation, pathAnimation, resizeAnimation, nil]]; group.duration = 0.7f; group.delegate = self; [group setValue:imageViewForAnimation forKey:@"imageViewBeingAnimated"]; [imageViewForAnimation.layer addAnimation:group forKey:@"savingAnimation"]; [imageViewForAnimation release]; </code></pre>

    1. COI got it.But i want to create animation effect something like i am having big image i should get resized image to big image's center then add animation path.How to get it.

    2. COI'm not sure what you're asking, but the animation above does three things: moves the image along a curved path, shrinks it as it moves so that it's tiny by the time it hits the end point, and fades it out as it moves. You can tweak the resizing by changing the from or to values, as needed.

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.
