Swift3.0 动画(缩放、晃动、翻转)

Swift3.0写－－2.左右晃动

func shakeAnimation(){//移除self.mineTopView.layer上的所有动画，可以避免多次重复添加self.mineTopView.layer.removeAllAnimations()        let momAnimation = CABasicAnimation(keyPath: "transform.rotation.z")        momAnimation.fromValue = NSNumber(value: -0.1) //左幅度        momAnimation.toValue = NSNumber(value: 0.1) //右幅度        momAnimation.duration = 0.1        momAnimation.repeatCount = HUGE //无限重复        momAnimation.autoreverses = true //动画结束时执行逆动画        self.momAnimation.isRemovedOnCompletion = false //切出此界面再回来动画不会停止        self.momAnimation.delegate = self//CAAnimationDelegate 代理中有动画的开始和结束        self.mineTopView.layer.add(momAnimation, forKey: "centerLayer")    }

//旋转动画    func rorateAnimation(holdView: UIView){        let momAnimation = CABasicAnimation(keyPath: "transform.rotation.z")        momAnimation.fromValue = NSNumber(value: 0) //左幅度        momAnimation.toValue = NSNumber(value: M_PI*2) //右幅度        momAnimation.duration = 1        momAnimation.repeatCount = HUGE //无限重复        holdView.layer.add(momAnimation, forKey: "centerLayer")    }

1.缩放

- (void)Animation{    // 设定为缩放    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];    // 动画选项设定    animation.duration = 2.0; // 动画持续时间    animation.repeatCount = HUGE_VALF; // 重复次数(无限)    animation.autoreverses = YES; // 动画结束时执行逆动画    // 缩放倍数    animation.fromValue = [NSNumber numberWithFloat:0.9]; // 开始时的倍率    animation.toValue = [NSNumber numberWithFloat:1.1]; // 结束时的倍率    // 添加动画    [self.moveView.layer addAnimation:animation forKey:@"scale-layer"];}

2.左右晃动

- (void)animation{ //z轴 CABasicAnimation *momAnimation = [CABasicAnimation     animationWithKeyPath:@"transform.rotation.z"];    momAnimation.fromValue = [NSNumber numberWithFloat:-0.1];//左幅度    momAnimation.toValue = [NSNumber numberWithFloat:0.1];//右幅度    momAnimation.duration = 1.5;    momAnimation.repeatCount = CGFLOAT_MAX;//无限重复    momAnimation.autoreverses = YES;//动画结束时执行逆动画    momAnimation.delegate = self;    [self.moveView.layer addAnimation:momAnimation forKey:@"centerLayer"];    }

3.翻转动画

- (void)transitionAnimation{    CGContextRef context=UIGraphicsGetCurrentContext();    [UIView beginAnimations:nil context:context];    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];//可选    [UIView setAnimationDuration:1.0];    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.moveView cache:YES];//UIViewAnimationTransitionCurlUp五种翻转效果可选    [UIView setAnimationDelegate:self];    [UIView commitAnimations];}

4.循环动画

[UIView animateWithDuration:timer animations:^{        //执行    } completion:^(BOOL finished) {       //结束后再执行（就是不知无限循环有多大危害）    }];
