设定动画的属性。以下是属性及其对应的说明：
C221A1BE-B020-41BF-B75F-4324E1A0011E.png
animation.duration = 2.5; // 动画持续时间
animation.repeatCount = 1; // 不重复
animation.beginTime = CACurrentMediaTime() + 2; // 2秒后执行
animation.autoreverses = YES; // 结束后执行逆动画
// 动画先加速后减速
animation.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseInEaseOut];
设定动画开始和结束帧时的状态。设定的值会变为KeyPath所指定的属性的值。

// 指定position属性（移动）
CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position"];
// 设定动画起始帧和结束帧
animation.fromValue = [NSValue valueWithCGPoint:CGPointMake(0, 0)]; // 起始点
animation.toValue = [NSValue valueWithCGPoint:CGPointMake(320, 480)]; // 终了点
