iOS动画和特效（一）UIView动画和CoreAnimation

UIView *animView =[UIView new];
animView.backgroundColor = [UIColor redColor];
animView.frame = CGRectMake(self.view.frame.size.width/2, 100, 100, 100);
[self.view addSubview:animView];

CABasicAnimation *leftAnim = [CABasicAnimation animationWithKeyPath:@"position"];

[leftAnim setToValue:[NSValue valueWithCGPoint:CGPointMake(animView.layer.position.x+100, animView.layer.position.y)]];

//x轴旋转动画
CABasicAnimation *xAnim = [CABasicAnimation animationWithKeyPath:@"transform.rotation.x"];
[xAnim setByValue:[NSNumber numberWithDouble:M_PI*500]];
xAnim.duration = 1.5;

//y轴旋转动画
CABasicAnimation *yAnim = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
[yAnim setByValue:[NSNumber numberWithDouble:M_PI*200]];

//缩放动画
CABasicAnimation *sAnim = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
// 动画选项设定
sAnim.autoreverses = YES; //动画结束时执行逆动画
sAnim.fromValue = [NSNumber numberWithDouble:0.1];//开始的倍率
sAnim.toValue = [NSNumber numberWithDouble:1.5];//结束的倍率

CAAnimationGroup *animGroup = [CAAnimationGroup animation];

animGroup.duration = 3.0;
animGroup.repeatCount = 1;
animGroup.animations = @[xAnim,yAnim,sAnim,leftAnim];
//这两个属性若不设置，动画执行后回复位
animGroup.removedOnCompletion = false;
animGroup.fillMode = kCAFillModeForwards;
animGroup.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];//加速运动
animGroup.delegate = self;
[animView.layer addAnimation:animGroup forKey:nil];

关键帧动画 CAKeyframeAnimation

UIView *animView =[UIView new];
animView.backgroundColor = [UIColor redColor];
animView.frame = CGRectMake(self.view.frame.size.width/2, 100, 100, 100);
[self.view addSubview:animView];

UIPanGestureRecognizer *tap = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(anim:)];

[animView addGestureRecognizer:tap];

- (void)anim:(UIPanGestureRecognizer *)tap{

CAKeyframeAnimation *keyframeAnim = [CAKeyframeAnimation animationWithKeyPath:@"position"];

//线段的位置移动
//  keyframeAnim.values = @[[NSValue valueWithCGPoint:CGPointMake(10, 100)],[NSValue valueWithCGPoint:CGPointMake(30, 100)],[NSValue valueWithCGPoint:CGPointMake(30, 120)],[NSValue valueWithCGPoint:CGPointMake(60, 120)],[NSValue valueWithCGPoint:CGPointMake(60, 100)],[NSValue valueWithCGPoint:CGPointMake(106, 210)],[NSValue valueWithCGPoint:CGPointMake(106, 410)],[NSValue valueWithCGPoint:CGPointMake(300, 310)]];

//弧线位置移动
CGMutablePathRef mutablePath = CGPathCreateMutable();
CGPathMoveToPoint(mutablePath, nil, 50, 50);
CGPathAddCurveToPoint(mutablePath, nil, 50, 50, 700, 300, 30, 500);
keyframeAnim.path = mutablePath;

keyframeAnim.duration = 0.3;

[tap.view.layer addAnimation:keyframeAnim forKey:nil];
}

//keyTimes：各个关键帧的时间控制

//caculationMode：动画计算模式。
kCAAnimationLinear: 线性模式，默认值
kCAAnimationDiscrete: 离散模式
kCAAnimationPaced:均匀处理，会忽略keyTimes
kCAAnimationCubic:平滑执行，对于位置变动关键帧动画运行轨迹更平滑
kCAAnimationCubicPaced:平滑均匀执行

转场效果

kCATransitionFade：淡入淡出，默认效果
kCATransitionMoveIn：新视图移动到就是图上方
kCATransitionPush:新视图推开旧视图
kCATransitionReveal：移走旧视图然后显示新视图

//苹果未公开的私有转场效果
cube:立方体
suckEffect:吸走的效果
oglFlip:前后翻转效果
rippleEffect:波纹效果

pageUnCurl:翻页下来
