Autoreverses
DurationDuration方法设定动画的属 性时,它将再次使用你的动画,而非默认的动画。
Speed
倍的速度播放。 这样的影响就是使持续时间减半。如果你指定的持续时间为一半的 持续时间。
BeginTime
这个属性在组动画中很有用。它根据父动画组的持续时间,指定了开始播放动画的时间。默认的是0.0.组 动画在下个段落中讨论“Animation Grouping”。
TimeOffset
如果一个时间偏移量是被设定,动画不会真正的可见,直到根据父动画组中的执行时间得到的时间都流逝了。
RepeatCount
RepeatDuration
下面这段英文摘自苹果官方文档，说的是fromValue toValue ByValue 怎么使用
/* The interpolation values are used as follows: *//** * Both fromValue and toValue are non-nil. Interpolates between fromValue and toValue. * fromValue and byValue are non-nil. Interpolates between fromValue and (fromValue + byValue). * byValue and toValue are non-nil. Interpolates between (toValue – byValue) and toValue. * fromValue is non-nil. Interpolates between fromValue and the current presentation value of the property. * toValue is non-nil. Interpolates between the current value of keyPath in the target layer’s presentation layer andtoValue. * byValue is non-nil. Interpolates between the current value of keyPath in the target layer’s presentation layer and that value * plus byValue. * All properties are nil. Interpolates between the previous value of keyPath in the target layer’s presentation layer and the * current value of keyPath in the target layer’s presentation layer. */
/*————————————————– * 其他的方法,还是属性等，都是继承而来的。 * 我们可以通过animationWithKeyPath键值对的方式来改变动画。 —————————————————-*//* animationWithKeyPath的值 */transform.scale// 比例转换transform.scale.x// 宽度比例转换transform.scale.y// 高度比例转换transform.rotation.z // 平面图的转换margin// 边缘zPosition// z轴位置backgroundColor // 背景颜色cornerRadius // 圆角borderWidth// 边框宽度bounds// 边界contents// 内容contentsRect // 内容矩形frame// 框架hidden// 隐藏的mask// 面具masksToBounds // 面具界限opacity// 透明度position// 位置shadowColor// 阴影颜色shadowOffset // 阴影偏移shadowOpacity // 阴影不透明shadowRadius // 阴影半径
