1. 常见的位移动画效果实现
- (void)positionAction
{
CABasicAnimation*posAnim = [CABasicAnimationanimationWithKeyPath:@"position"];
// 起始坐标点位置
CGPointstartP =CGPointMake(88,88);
// 终点坐标点位置
CGPointendP =CGPointMake(10,333);
//从某个点开始
posAnim.fromValue= [NSValuevalueWithCGPoint:startP];
//到某个点结束
posAnim.toValue= [NSValuevalueWithCGPoint:endP];
//多少时间内完成这个动画
posAnim.duration=2;
//保持当前最新的位置
posAnim.fillMode=kCAFillModeForwards;
//在完成的时候,保留动画
posAnim.removedOnCompletion=NO;
//原路径返回
posAnim.autoreverses=YES;
//添加到myView上
[self.myView.layeraddAnimation:posAnimforKey:@"11"];
}
2. 翻转,类似于电子书软件的翻页效果
- (void)CATransionAction
{
self.myView.image= [UIImageimageNamed:@“YztciOS"];
CATransition*tranAnim = [CATransitionanimation];
tranAnim.type=kCATransitionMoveIn;
tranAnim.subtype=kCATransitionFromRight;
[self.myView.layeraddAnimation:tranAnimforKey:nil];
}
3. 抖动,类似于iOS系统长按删除App的效果
- (void)appDeleteAct
{
CAKeyframeAnimation*anim = [CAKeyframeAnimationanimationWithKeyPath:@"transform.rotation.z"];
CGFloatleftF =M_PI_4/45*10;
CGFloatrightF =M_PI_4/45* -10;
//向左转动10°,再向右转动10°,再向左转动10°
anim.values=@[@(leftF),@(rightF),@(leftF)];
//单位时间内
anim.duration=1;
//转动次数
anim.repeatCount=MAXFLOAT;
[self.myView.layeraddAnimation:animforKey:nil];
}
4. 缩放效果
- (void)scaleAnimation
{
CABasicAnimation*anim = [CABasicAnimationanimationWithKeyPath:@"transform.scale"];
anim.fromValue=@1;
anim.toValue=@.3;
anim.repeatCount=MAXFLOAT;
anim.duration=.8;
anim.autoreverses=YES;
//控制动画单位时间内的速度
anim.timingFunction= [CAMediaTimingFunctionfunctionWithName:kCAMediaTimingFunctionEaseIn];
[self.myView.layeraddAnimation:animforKey:nil];
}
5. 转动效果
- (void)tranAnimation
{
//删除myView.layer上叫做tranfName的动画
[self.myView.layerremoveAnimationForKey:@"tranfName"];
CABasicAnimation*tranAnim = [CABasicAnimationanimationWithKeyPath:@"transform.rotation.z"];
//旋转角度
tranAnim.toValue= @M_PI_4;
//动画时间
tranAnim.duration=0.5;
//转动次数
tranAnim.repeatCount=MAXFLOAT;
//累加
tranAnim.cumulative=YES;
//添加动画
[self.myView.layeraddAnimation:tranAnimforKey:@"tranfName"];
}
6. 透明度渐变效果
- (void)opacityAct
{
CABasicAnimation*anim = [CABasicAnimationanimationWithKeyPath:@"opacity"];
anim.fromValue=@1;
anim.toValue=@0;
anim.duration=1;
anim.repeatCount=MAXFLOAT;
anim.autoreverses=YES;
[self.myView.layeraddAnimation:animforKey:nil];
}
7. 多个坐标点的运动轨迹效果,用贝瑟尔曲线进行实现
- (void)keyfromPathAction
{
CAKeyframeAnimation*pathAnim = [CAKeyframeAnimationanimationWithKeyPath:@"position"];
UIBezierPath*path = [UIBezierPathbezierPathWithOvalInRect:CGRectMake(99,99,200,200)];
//将路径赋值给动画
pathAnim.path= path.CGPath;
//时间间隔
pathAnim.duration=5;
pathAnim.repeatCount=MAXFLOAT;
[self.myView.layeraddAnimation:pathAnimforKey:nil];
}
8. 多个坐标点的运动轨迹效果,用Value进行实现
- (void)muchPoint
{
CAKeyframeAnimation*anim = [CAKeyframeAnimationanimationWithKeyPath:@"position"];
NSValue*v1 = [NSValuevalueWithCGPoint:CGPointMake(88,88)];
NSValue*v2 = [NSValuevalueWithCGPoint:CGPointMake(188,188)];
NSValue*v3 = [NSValuevalueWithCGPoint:CGPointMake(4,88)];
NSValue*v4 = [NSValuevalueWithCGPoint:CGPointMake(88,2)];
NSValue*v5 = [NSValuevalueWithCGPoint:CGPointMake(0,488)];
NSValue*v6 = [NSValuevalueWithCGPoint:CGPointMake(288,388)];
anim.values=@[v1,v2,v3,v4,v5,v6];
anim.duration=5;
//让轨迹保存在最终位置
anim.fillMode=kCAFillModeForwards;
//在动画完成后,保留动画
anim.removedOnCompletion=NO;
//原路径返回
anim.autoreverses=YES;
//添加核心动画
[self.myView.layeraddAnimation:animforKey:nil];
}
9. 多个核心动画以组合的方式同时实现(常用,核心动画重点,必须熟练掌握)
- (void)groupAnim
{
[self.view.layerremoveAllAnimations];
//跳动效果
CABasicAnimation*scaleAnim = [CABasicAnimationanimationWithKeyPath:@"transform.scale"];
scaleAnim.fromValue=@2;
scaleAnim.toValue=@.4;
//旋转效果
CABasicAnimation*tranAnim = [CABasicAnimationanimationWithKeyPath:@"transform.rotation.z"];
tranAnim.toValue= @M_PI_4;
//闪烁效果
CABasicAnimation*opacityAnim = [CABasicAnimationanimationWithKeyPath:@"opacity"];
opacityAnim.fromValue=@1;
opacityAnim.toValue=@0;
//多点运动轨迹(path)
CAKeyframeAnimation*posAnim = [CAKeyframeAnimationanimationWithKeyPath:@"position"];
UIBezierPath*path = [UIBezierPathbezierPath];
[pathmoveToPoint:CGPointMake(99,99)];
[pathaddLineToPoint:CGPointMake(11,11)];
[pathaddLineToPoint:CGPointMake(199,399)];
[pathclosePath];
posAnim.path= path.CGPath;
//动画组合效果
CAAnimationGroup*groupAnim = [CAAnimationGroupanimation];
groupAnim.animations=@[scaleAnim,tranAnim,opacityAnim,posAnim];
groupAnim.duration=5;
groupAnim.fillMode=kCAFillModeForwards;
groupAnim.removedOnCompletion=NO;
[self.myView.layeraddAnimation:groupAnimforKey:nil];
}
