Scaling not as smooth in 3.0 as in 2.x

Question

I have a CATiledLayer backed UIView that is added to UIScrollView and it is returned as view to be scaled in response to -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView delegate method.

Now the problem is that scaling on a scale falling between the 2x steps provided by CATiledLayer (like for example 1.333) results in very pixelated image when I compile and test against 3.0 SDK. In 2.2.1 the scaling is much smoother.

I tried to set layer's minificationFilter to kCAFilterTrilinear, but that resulted in a way too blurry image.

Any ideas?

Answer 1

After some playing, I discovered that only the 2.x Simulator smoothens the scaled image. On the real device with 2.x SDK, the scaling is the same as on 3.0.
