x轴旋转：
CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.rotation.x"];
theAnimation.duration=1;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:3.1415926];
 [yourView.layer addAnimation:theAnimation forKey:@"animateTransformx"];

y轴旋转：
CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
theAnimation.duration=1;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:3.1415926];
 [yourView.layer addAnimation:theAnimation forKey:@"animateTransformy"];

z轴旋转：
CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
theAnimation.duration=1;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:3.1415926];
 [yourView.layer addAnimation:theAnimation forKey:@"animateTransformz"];

以上缩放是以view的中心点为中心缩放的，如果需要自定义缩放点，可以设置卯点：
//中心点
[yourView.layer setAnchorPoint:CGPointMake(0.5, 0.5)];

//左上角
[yourView.layer setAnchorPoint:CGPointMake(0, 0)];

//右下角
[yourView.layer setAnchorPoint:CGPointMake(1, 1)];

可设参数：
theAnimation.repeatCount = 5;
theAnimation.autoreverses = YES;
theAnimation.removedOnCompletion = YES;
