Animation

1、shake

CABasicAnimation *shake = [CABasicAnimation animationWithKeyPath:@"transform"];
        shake.duration = 0.13;
        shake.autoreverses = YES;
        shake.repeatCount  = MAXFLOAT;
        shake.removedOnCompletion = NO;
        shake.fromValue = [NSValue valueWithCATransform3D:CATransform3DRotate(self.layer.transform,-rotation, 0.0 ,0.0 ,1.0)];
        shake.toValue   = [NSValue valueWithCATransform3D:CATransform3DRotate(self.layer.transform, rotation, 0.0 ,0.0 ,1.0)];

        [self.layer addAnimation:shake forKey:@"shakeAnimation"];
