UIImageView视图内容按比例缩小并淅淅隐去

在IPHONE上使用标准core animation调用
- (void) action: (id) sender
{
//self.navigationItem.rightBarButtonItem = nil;

// Adapted from Lucas Newman's sample code (www.lucasnewman.com)
   UIView *theView = [self.view viewWithTag:101];
   [CATransaction begin];
    [CATransaction setValue:[NSNumber numberWithFloat:ANIMATION_DURATION] forKey:kCATransactionAnimationDuration];

    // scale it down
    CABasicAnimation *shrinkAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
   shrinkAnimation.delegate = self;
    shrinkAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
    shrinkAnimation.toValue = [NSNumber numberWithFloat:0.0];
   [[theView layer] addAnimation:shrinkAnimation forKey:@"shrinkAnimation"];

   // fade it out
    CABasicAnimation *fadeAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"];
    fadeAnimation.toValue = [NSNumber numberWithFloat:0.0];
    fadeAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
    [[theView layer] addAnimation:fadeAnimation forKey:@"fadeAnimation"];

   // make it jump a couple of times
    CAKeyframeAnimation *positionAnimation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    CGMutablePathRef positionPath = CGAutorelease(CGPathCreateMutable());
    CGPathMoveToPoint(positionPath, NULL, [theView layer].position.x, [theView layer].position.y);
    CGPathAddQuadCurveToPoint(positionPath, NULL, [theView layer].position.x, - [theView layer].position.y, [theView layer].position.x, [theView layer].position.y);
    CGPathAddQuadCurveToPoint(positionPath, NULL, [theView layer].position.x, - [theView layer].position.y * 1.5, [theView layer].position.x, [theView layer].position.y);
    CGPathAddQuadCurveToPoint(positionPath, NULL, [theView layer].position.x, - [theView layer].position.y * 1.25, [theView layer].position.x, [theView layer].position.y);
    positionAnimation.path = positionPath;
    positionAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
    [[theView layer] addAnimation:positionAnimation forKey:@"positionAnimation"];

   [CATransaction commit];
}
