动画（Core Animation）

1、CABaseAnimation

 */

    anima.duration = 1.0f;
    ///*如果实现下面属性，在动画执行完毕后，图层会保持显示动画执行后的状态
    anima.fillMode = kCAFillModeForwards;
    anima.removedOnCompletion = NO;
    //*/
    anima.repeatCount = 20;
    [tempView.layer addAnimation:anima forKey:@"positionAnimation"];

/**
 渐隐动画
 */

2、CAKeyframeAnimation

- (void)testPathAnimation
{
    
    CGFloat tempViewWidth = 50;

    /*
     //矩形
     + (instancetype)bezierPathWithRect:(CGRect)rect;
     
     //以矩形框为切线画圆
     + (instancetype)bezierPathWithOvalInRect:(CGRect)rect;
     
     //带圆角的矩形框
     + (instancetype)bezierPathWithRoundedRect:(CGRect)rect cornerRadius:(CGFloat)cornerRadius;
     
     //画圆弧
     + (instancetype)bezierPathWithArcCenter:(CGPoint)center radius:(CGFloat)radius startAngle:(CGFloat)startAngle endAngle:(CGFloat)endAngle clockwise:(BOOL)clockwise;
     */
     CAKeyframeAnimation *anima = [CAKeyframeAnimation animationWithKeyPath:@"position"];

3、CAAnimationGroup

    CGFloat tempViewWidth = 50;
    CGFloat tempViewY = 300;
    
    UIView *tempView = [[UIView alloc] initWithFrame:CGRectMake((JnScreenWidth-tempViewWidth)/2, tempViewY, tempViewWidth, tempViewWidth)];

    [self.view addSubview:tempView];
    
    CAKeyframeAnimation *anima1 = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    NSValue *value0 = [NSValue valueWithCGPoint:CGPointMake(0, JnScreenHeight/2-50)];
    NSValue *value1 = [NSValue valueWithCGPoint:CGPointMake(JnScreenWidth/3, JnScreenHeight/2-50)];
    NSValue *value2 = [NSValue valueWithCGPoint:CGPointMake(JnScreenWidth/3, JnScreenHeight/2+50)];
    NSValue *value3 = [NSValue valueWithCGPoint:CGPointMake(JnScreenWidth*2/3, JnScreenHeight/2+50)];
    NSValue *value4 = [NSValue valueWithCGPoint:CGPointMake(JnScreenWidth*2/3, JnScreenHeight/2-50)];
    NSValue *value5 = [NSValue valueWithCGPoint:CGPointMake(JnScreenWidth, JnScreenHeight/2-50)];
    anima1.values = [NSArray arrayWithObjects:value0,value1,value2,value3,value4,value5, nil];
    //缩放动画
    CABasicAnimation *anima2 = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
    anima2.fromValue = [NSNumber numberWithFloat:0.8f];
    anima2.toValue = [NSNumber numberWithFloat:2.0f];
    //旋转动画
    CABasicAnimation *anima3 = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
    anima3.toValue = [NSNumber numberWithFloat:M_PI*4];
    //组动画
    CAAnimationGroup *groupAnimation = [CAAnimationGroup animation];
    groupAnimation.animations = [NSArray arrayWithObjects:anima1,anima2,anima3, nil];
    groupAnimation.duration = 4.0f;
    [tempView.layer addAnimation:groupAnimation forKey:@"groupAnimation"];
    
}

4、CATransition

//------------- type：动画过渡类型 -------------
/* Apple官方的SDK其实只提供了四种过渡效果。
kCATransitionFade 渐变效果
kCATransitionMoveIn 进入覆盖效果
kCATransitionPush 推出效果
kCATransitionReveal 揭露离开效果
 */
/* 这类是API引入的，在苹果官网是不会承认的，所以不建议使用
 cube 立方体效果
 suckEffect 犹如一块布被抽走
 oglFlip上 下翻转效果
 rippleEffect 滴水效果
 pageCurl 向左翻页
 pageUnCurl 向下翻页
 */

//------------- subtype：动画过渡方向 -------------
/*
 kCATransitionFromRight 从右侧进入
 kCATransitionFromLeft 从左侧进入
 kCATransitionFromTop 从顶部进入
 kCATransitionFromBottom 从底部进入
 */

/*
 startProgress：动画起点(在整体动画的百分比)
 endProgress：动画终点(在整体动画的百分比)
 */
