CABasicAnimation键

Mos*_*wad 10 iphone xcode objective-c ipad ios

我试图知道所用的所有密钥是什么 CABasicAnimation

像这个:

CABasicAnimation *imageRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];

旋转...我在哪里可以找到所有可能的键？并感谢前进

在对其中一个答案的评论中提到了此来源，但希望以后发现该问题的人可以接受此信息，有关此问题的正确列表是发布在Apple文档上的此页面：

这些链接中列出了以下关键路径：

（除非另有说明，否则CALayer属性使用默认的CABasicAnimation）

卡拉耶

  • anchorPoint：CGPoint
  • backgroundColor：CGColor？
  • backgroundFilters：[CIFilter]？（使用默认的CATransition，使用默认的CABasicAnimation对过滤器的子属性进行动画处理）
  • borderColor：CGColor？
  • borderWidth：CGFloat
  • 边界：CGRect
  • compositingFilter：CIFilter吗？（使用默认的CATransition，使用默认的CABasicAnimation对过滤器的子属性进行动画处理）
  • 内容：CGImage？
  • contentsRect：CGRect
  • cornerRadius：CGFloat
  • doubleSided：布尔（无默认动画）
  • 过滤器：__ [CIFilter]？（使用默认的CATransition，使用默认的CABasicAnimation对过滤器的子属性进行动画处理）
  • 框架：CGRect（!!不能动画！使用范围和位置）
  • 隐藏：布尔
  • 面具：CALayer？
  • masksToBounds：布尔
  • 不透明度：浮动（0 <=不透明度<= 1）
  • 位置：CGPoint
  • shadowColor：CGColor？
  • shadowOffset：CGSize（默认为（0，-3））
  • shadowOpacity：浮动（0 <= shadowOpacity <= 1）
  • shadowPath：CGPath？
  • shadowRadius：CGFloat（默认为3）
  • 子层：[CALayer]？
  • sublayerTransform：CATransform3D
  • 转换：CATransform3D
  • 位置：CGFloat

CALayer默认隐含CABasicAnimation **：持续时间 = 0.25s或当前事务的持续时间。
CALayer默认隐含的CATransition **：持续时间 = 0.25s或当前事务的持续时间，类型= kCATransitionFade，开始进度= 0，结束进度= 1

CIFilter（仅限macOS）

  • 名称：字串
  • 启用：布尔

CATransform3D

  • rotation.x：NSNumber（弧度）
  • rotation.y：NSNumber（弧度）
  • rotation.z：NSNumber（弧度）
  • rotation：NSNumber（弧度）（与rotation.z相同）
  • scale.x：NSNumber
  • scale.y：NSNumber
  • scale.z：NSNumber
  • scale：NSNumber（所有三个比例因子的平均值）
  • translation.x：NSNumber
  • translation.y：NSNumber
  • translation.z：NSNumber
  • 翻译：NSValue含有NSSize或CGSize

CGPoint

  • x：CGFloat
  • y：CGFloat

CG尺寸

  • 宽度：CGFloat
  • 高度：CGFloat

CGRect

  • 来源：CGPoint
  • origin.x：CGFloat
  • 来源：CGFloat
  • 尺寸：CG 尺寸
  • size.width：CGFloat
  • size.height：CGFloat

你可以简单地写： CABasicAnimation(keyPath: #keyPath(CAShapeLayer.strokeColor))

另外，使用 command+shift+o，打开，例如 CALayer.h 并观看评论。**Apple 团队提供有关动画功能的信息

对于动画键：

====漂亮的包装器；用法示例====

请回复这条关于不正确的消息，如果你会看到

extension CABasicAnimation {
        convenience init(_ key: CAPropertyAnimation.Key, duration: Double) {
        self.init(keyPath: key.keyPath)
        self.duration = duration
    }
}
