但是，我还没能找出 LevelsOfDetail 和 LevelsOfDetailBias 属性的CATiledLayer是为。我可以设置任何值组合，不能发现差异。苹果对房产的帮助对我没有任何解释。
However, I have not been able to figure out what "LevelsOfDetail" and "LevelsOfDetailBias" properties of CATiledLayer are for. I can set any value combination and cannot spot a difference. Apple's help on the properties doesn't explain anything to me.
有人可以解释吗？
