关于ios动画

动画分为两种UIView层动画 CALayer层动画。

UIView层动画分为两种类型：

1.属性动画
2.过渡动画

属性动画之block

    [UIView animateWithDuration:1 animations:^{        self.AView.alpha = 0.3;    }];    [UIView animateWithDuration:3 animations:^{        self.AView.transform = CGAffineTransformMakeRotation(M_PI_4);        self.AView.backgroundColor = [UIColor grayColor];        self.AView.bounds = CGRectMake(0, 0, 100, 100);    } completion:^(BOOL finished) {        NSLog(@"结束");    }];

[UIView animateWithDuration:2 delay:2 options:UIViewAnimationOptionAllowUserInteraction  animations:^{        self.AView.transform = CGAffineTransformMakeRotation(M_PI_4);        self.AView.backgroundColor = [UIColor grayColor];        self.AView.bounds = CGRectMake(0, 0, 100, 100);    } completion:^(BOOL finished) {        self.AView.backgroundColor = [UIColor redColor];    }];

[UIView animateWithDuration:2 delay:2 usingSpringWithDamping:0.1 initialSpringVelocity:2 options:UIViewAnimationOptionAllowUserInteraction animations:^{          self.AView.transform = CGAffineTransformMakeRotation(M_PI_4);          self.AView.backgroundColor = [UIColor grayColor];          self.AView.bounds = CGRectMake(0, 0, 100, 100);      } completion:^(BOOL finished) {      }]；

过渡动画之 普通翻页效果

 UIView *containerView =self.view.superview;    [UIViewtransitionWithView:containerView duration:2options:UIViewAnimationOptionTransitionCurlUpanimations:^{        [self.viewremoveFromSuperview] ;        [containerView addSubview:XVC.view];    } completion:^(BOOL finished) {    }];

CALayer层动画

CAlayer层在做属性动画时并不是所有的属性都可以做动画 只有属性后面带Animatable的才可以做动画。

 CABasicAnimation *basicAnimation = [CABasicAnimationanimationWithKeyPath:@"backgroundColor"];    basicAnimation.duration =2;    basicAnimation.fromValue = (__bridgeid)([UIColoryellowColor].CGColor);    basicAnimation.toValue = (__bridgeid)([UIColorredColor].CGColor);    [self.AView.layeraddAnimation:basicAnimation forKey:@"BS"];

类似于QQ的弹框的抖动效果

CAKeyframeAnimation *keyFrameAnimation = [CAKeyframeAnimationanimationWithKeyPath:@"position.x"];    CGFloat x =self.AView.center.x;    CGFloat leftX = x -10;    CGFloat rightX = x +10;    NSNumber *X = [NSNumbernumberWithFloat:x];    NSNumber *leftx = [NSNumbernumberWithFloat:leftX];    NSNumber *righty = [NSNumbernumberWithFloat:rightX];    NSArray *values =@[X,leftx,X,righty,X,leftx,X,righty,X];    keyFrameAnimation.values = values;    [self.AView.layeraddAnimation:keyFrameAnimation forKey:@"keyFrame"];

CATransition 转场动画具有方块翻页效果

 CATransition *catransition = [CATransitionanimation];    //  1获取self.view.superView    UIView *view =self.view.superview;    catransition.type =@"cube";    catransition.duration =3;    catransition.startProgress =0.3; // 开始动画    catransition.endProgress =0.8; // 结束动画    //  2给self.view.superView添加动画    [view.layeraddAnimation:catransition forKey:@"catransition"];    //  3移除原来的View，添加新的View    [self.viewremoveFromSuperview];    XViewController *XVC = [self.storyboardinstantiateViewControllerWithIdentifier:@"X"];    [view addSubview:XVC.view];

CAAnimationGroup可融合前面的动画 做出多动画效果

 CAAnimationGroup *group = [CAAnimationGroupanimation];    CABasicAnimation *basicAnimation = [CABasicAnimationanimationWithKeyPath:@"backgroundColor"];    basicAnimation.duration =2;    basicAnimation.fromValue = (__bridgeid)([UIColoryellowColor].CGColor);    CAKeyframeAnimation *keyFrameAnimation = [CAKeyframeAnimationanimationWithKeyPath:@"position.x"];    CGFloat x =self.AView.center.x;    CGFloat leftX = x -10;    CGFloat rightX = x +10;    NSNumber *X = [NSNumbernumberWithFloat:x];    NSNumber *leftx = [NSNumbernumberWithFloat:leftX];    NSNumber *righty = [NSNumbernumberWithFloat:rightX];    NSArray *values =@[X  ,leftx,X,righty,X,leftx,X,righty,X];    keyFrameAnimation.values = values;    group.duration =2;    group.animations =@[basicAnimation,keyFrameAnimation];    [self.AView.layeraddAnimation:group forKey:@"group"];
