ios animation 动画效果实现

1.过渡动画 CATransition

   CATransition *animation = [CATransition animation];

    [animation setDuration:1.0];

    [animation setType:kCATransitionFade];

    [animation setSubtype:kCATransitionFromLeft];

    [_imgPic.layer addAnimation:animation forKey:nil];

说明:

  (1).Duration 延迟

  (2).Type

    kCATransitionFade      // 交叉淡化过渡(不支持过渡方向)

    kCATransitionMoveIn   // 新视图移到旧视图上面

    kCATransitionPush    // 新视图把旧视图推出去

      kCATransitionReveal   // 将旧视图移开,显示下面的新视图

    cube     // 立方体翻滚效果

    oglFlip  // 上下左右翻转效果

    suckEffect   // 收缩效果,如一块布被抽走(不支持过渡方向)

    rippleEffect // 滴水效果(不支持过渡方向)

    pageCurl     // 向上翻页效果

    pageUnCurl   // 向下翻页效果

    cameraIrisHollowOpen   // 相机镜头打开效果(不支持过渡方向)

    cameraIrisHollowClose  // 相机镜头关上效果(不支持过渡方向)

2.路径动画  CAKeyframeAnimation

    CAKeyframeAnimation *ani=[CAKeyframeAnimation animation];
CGMutablePathRef aPath=CGPathCreateMutable(); CGPathMoveToPoint(aPath, nil, , );
CGPathAddCurveToPoint(aPath, nil,
, ,
, ,
, ); ani.path=aPath;
ani.duration=;
ani.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
ani.rotationMode=@"autoReverse";
[redView.layer addAnimation:ani forKey:@"position"];

//特殊曲线 贝塞尔曲线

//贝塞尔曲线路径
UIBezierPath *movePath = [UIBezierPath bezierPath];
[movePath moveToPoint:CGPointMake(0.0, 0.0)];
[movePath addQuadCurveToPoint:CGPointMake(self.view.frame.size.width/2.0, self.view.frame.size.height/2.0) controlPoint:CGPointMake(self.view.frame.size.width, self.view.frame.size.height)];

说明:(1).moveToPoint :动画起始位置

   (2).轨迹

   - (void)addQuadCurveToPoint:(CGPoint)endPoint controlPoint:(CGPoint)controlPoint;

   //endPoint 完成位置  controllerPoint  轨迹中的位置

3.基本类型  CABasicAnimation 事例

  //背景色动画
CABasicAnimation *animation=[CABasicAnimation animation];
//设置颜色
animation.toValue=(id)[UIColor blueColor].CGColor;
//动画时间
animation.duration=;
//是否反转变为原来的属性值
animation.autoreverses=YES;
//把animation添加到图层的layer中,便可以播放动画了。forKey指定要应用此动画的属性
[self.view.layer addAnimation:animation forKey:@"backgroundColor"]; //缩放动画
CABasicAnimation *scaleAnim = [CABasicAnimation animationWithKeyPath:@"transform"];
scaleAnim.fromValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(0.1, 0.1, 1.0)];
scaleAnim.toValue = [NSValue valueWithCATransform3D:CATransform3DIdentity];
scaleAnim.removedOnCompletion = YES; //透明动画
CABasicAnimation *opacityAnim = [CABasicAnimation animationWithKeyPath:@"alpha"];
opacityAnim.fromValue = [NSNumber numberWithFloat:1.0];
opacityAnim.toValue = [NSNumber numberWithFloat:0.1];
opacityAnim.removedOnCompletion = YES;

4. UIViewAnimationWithBlocks

+ (void)transitionWithView:(UIView *)view duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^ __nullable)(void))animations completion:(void (^ __nullable)(BOOL finished))completion
+ (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^ __nullable)(BOOL finished))completion

// UIViewAnimationOptions

UIViewAnimationOptionLayoutSubviews //提交动画的时候布局子控件,表示子控件将和父控件一同动画。

UIViewAnimationOptionAllowUserInteraction //动画时允许用户交流,比如触摸

UIViewAnimationOptionBeginFromCurrentState //从当前状态开始动画

UIViewAnimationOptionRepeat //动画无限重复

UIViewAnimationOptionAutoreverse //执行动画回路,前提是设置动画无限重复

UIViewAnimationOptionOverrideInheritedDuration //忽略外层动画嵌套的执行时间

UIViewAnimationOptionOverrideInheritedCurve //忽略外层动画嵌套的时间变化曲线

UIViewAnimationOptionAllowAnimatedContent //通过改变属性和重绘实现动画效果,如果key没有提交动画将使用快照

UIViewAnimationOptionShowHideTransitionViews //用显隐的方式替代添加移除图层的动画效果

UIViewAnimationOptionOverrideInheritedOptions //忽略嵌套继承的选项

//时间函数曲线相关

UIViewAnimationOptionCurveEaseInOut //时间曲线函数,由慢到快

UIViewAnimationOptionCurveEaseIn //时间曲线函数,由慢到特别快

UIViewAnimationOptionCurveEaseOut //时间曲线函数,由快到慢

UIViewAnimationOptionCurveLinear //时间曲线函数,匀速

//转场动画相关的

UIViewAnimationOptionTransitionNone //无转场动画

UIViewAnimationOptionTransitionFlipFromLeft //转场从左翻转

UIViewAnimationOptionTransitionFlipFromRight //转场从右翻转

UIViewAnimationOptionTransitionCurlUp //上卷转场

UIViewAnimationOptionTransitionCurlDown //下卷转场

UIViewAnimationOptionTransitionCrossDissolve //转场交叉消失

UIViewAnimationOptionTransitionFlipFromTop //转场从上翻转

UIViewAnimationOptionTransitionFlipFromBottom //转场从下翻转
