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;
