how can use cagradientlayer efficiently draw gradient around circle / angles? i made 1 underneath of project . uses bitmap context drawing cagradientlayer far more efficient. unfortunately figure out how make linear gradients it. gradient layers support linear gradients. however, if @ interface gradient layers, includes type property. right type defined kcagradientlayeraxial (linear). the fact there type property suggests apple adding more types @ future date, , radial gradients seem like addition. you might @ creating own custom subclass of cagradientlayer draws radial gradients linear. i've seen demo projects on net create custom calayer subclasses.
