实现view放大再缩小的效果
 
- (void)viewDidLoad {      [super viewDidLoad];  layer=[CALayer layer];  layer.frame=CGRectMake(50, 200, 50, 50);  layer.backgroundColor=[UIColor orangeColor].CGColor;  layer.cornerRadius=8.0f;  CABasicAnimation *animation=[CABasicAnimation animationWithKeyPath:@"transform.translation.y"];  animation.duration=4.0f;  animation.autoreverses=NO;  animation.repeatCount=1;  animation.toValue=[NSNumber numberWithInt:-10];  animation.fromValue=[NSNumber numberWithInt:200];  animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];  CABasicAnimation *animationZoomIn=[CABasicAnimation animationWithKeyPath:@"transform.scale"];  animationZoomIn.duration=2.0f;  animationZoomIn.autoreverses=NO;  animationZoomIn.repeatCount=1;  animationZoomIn.toValue=[NSNumber numberWithFloat:1.56];  animationZoomIn.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];  CABasicAnimation *animationZoomOut=[CABasicAnimation animationWithKeyPath:@"transform.scale"];  animationZoomOut.beginTime=2.0f;  animationZoomOut.duration=2.0f;  animationZoomOut.autoreverses=NO;  animationZoomOut.repeatCount=1;  animationZoomOut.toValue=[NSNumber numberWithFloat:.01];  animationZoomOut.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];  CAAnimationGroup *group=[CAAnimationGroup animation];  group.duration=4.0f;  group.animations=[NSArray arrayWithObjects: animation, animationZoomIn, animationZoomOut,nil];  group.removedOnCompletion=NO;  group.fillMode=kCAFillModeForwards;  [layer addAnimation:group forKey:nil];  [self.view.layer addSublayer:layer];  //layer.hidden=YES;  }
