iOS 动画(2)

此处设置的动画是对UIImageView的CALayer设置

    _imagelayer = [CALayer layer];    _imagelayer.cornerRadius =6;    _imagelayer.borderWidth = 1;    _imagelayer.borderColor =[UIColor blueColor].CGColor;    _imagelayer.masksToBounds = YES;    _imagelayer.frame = CGRectMake(30, 30, 100, 115);    _imagelayer.contents = (id)[[UIImage imageNamed:@"icon_baiban"]CGImage];    [self.view.layer addSublayer:_imagelayer];

下面是动画方法

//位移-(void)move{    CGPoint fromPoint = _imagelayer.position;    CGPoint toPoint = CGPointMake(fromPoint.x +80, fromPoint.y);    CABasicAnimation *anim =[CABasicAnimation animationWithKeyPath:@"pasition"];    anim.fromValue =[NSValue valueWithCGPoint:fromPoint];    anim.toValue = [NSValue valueWithCGPoint:toPoint];    anim.duration = 0.5;    _imagelayer.position = toPoint;    anim.removedOnCompletion = YES;    [_imagelayer addAnimation:anim forKey:nil];}//旋转-(void)rotate{     CABasicAnimation *anim =[CABasicAnimation animationWithKeyPath:@"transform"];    CATransform3D fromeValue = _imagelayer.transform;    anim.fromValue = [NSValue valueWithCATransform3D:fromeValue];    CATransform3D toValue = CATransform3DRotate(fromeValue,  M_PI, 1, 0, 0);    anim.toValue = [NSValue valueWithCATransform3D:toValue];    anim.duration = 0.5;    _imagelayer.transform = toValue;    anim.removedOnCompletion = YES;    [_imagelayer addAnimation:anim forKey:nil];}//缩放-(void)scale{    CAKeyframeAnimation *anim =[CAKeyframeAnimation animationWithKeyPath:@"transform"];    anim.values =[NSArray arrayWithObjects:[NSValue valueWithCATransform3D:_imagelayer.transform],[NSValue     valueWithCATransform3D:CATransform3DScale(_imagelayer.transform, 0.2, 0.2, 1)],[NSValue  valueWithCATransform3D:CATransform3DScale(_imagelayer.transform, 2, 2, 1)],[NSValue valueWithCATransform3D:_imagelayer.transform], nil];    anim.duration =5;    anim.removedOnCompletion = YES;    [_imagelayer addAnimation:anim forKey:nil];}//动画组-(void)group{    CGPoint fromPoint = _imagelayer.position;    CGPoint toPoint =CGPointMake(280, fromPoint.y + 200);    CABasicAnimation *moveAnim =[CABasicAnimation animationWithKeyPath:@"position"];    moveAnim.fromValue =[NSValue valueWithCGPoint:fromPoint];    moveAnim.toValue =[NSValue valueWithCGPoint:toPoint];    moveAnim.removedOnCompletion = YES;    CABasicAnimation *transform =[CABasicAnimation animationWithKeyPath:@"transform"];    CATransform3D fromeValue =_imagelayer.transform;    transform.fromValue =[NSValue valueWithCATransform3D:fromeValue];    CATransform3D scaleValue = CATransform3DScale(fromeValue, 0.5, 0.5, 1);        CATransform3D rotateValue = CATransform3DRotate(fromeValue, M_PI, 0, 0, 1);    CATransform3D tovalue =CATransform3DConcat(scaleValue, rotateValue);    transform.toValue =[NSValue valueWithCATransform3D:tovalue];    transform.cumulative = YES;    transform.repeatCount= 2;    transform.duration = 3;    CAAnimationGroup *animGroup = [CAAnimationGroup animation];    animGroup.animations = [NSArray arrayWithObjects:moveAnim,transform, nil];    animGroup.duration =6;    [_imagelayer addAnimation:animGroup forKey:nil];}
