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
