CALayer 缩放动画
//放大
? ? ? ? CAKeyframeAnimation* animation = [CAKeyframeAnimation animationWithKeyPath:@"transform"];
? ? ? ? NSMutableArray *values = [NSMutableArray array];
? ? ? ? [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(0.9f, 0.9f, 1.0f)]];
? ? ? ? [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(1.0f, 1.0f, 1.0f)]];
? ? ? ? animation.values = values;
? ? ? ? animation.duration = duration;
? ? ? ? animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
? ? ? ? [aLayer addAnimation:animation forKey:@"transform"];

该代码可实现CAlayer的缩放
