Zoom UILabel & Re-render font at correct size

Question

I have a multi-line UILabel that I want to enable zooming on.

I embedded it with a UIScrollView and set min zoom to .25 and max zoom to 4.

Answer 1

the correct way to substitute a CALayer with a CATiledLayer is as follow:

+ (Class)layerClass {
    return [CATiledLayer class]; 
}

apart, you've to set your bias detail and whatever you need.
