用CAGradientLayer类来实现
CAGradientLayer *itemChartLayer = [CAGradientLayer layer];
itemChartLayer.colors = @[(__bridge id)startColor.CGColor,
(__bridge id)endColor.CGColor];
itemChartLayer.startPoint = CGPointMake(0, 0);
itemChartLayer.endPoint = CGPointMake(0, 1);
startpoint和endPoint是颜色分割点
CAGradientLayer *itemChartLayer = [CAGradientLayer layer];
itemChartLayer.colors = @[(__bridge id)startColor.CGColor,
(__bridge id)endColor.CGColor];
itemChartLayer.startPoint = CGPointMake(0, 0);
itemChartLayer.endPoint = CGPointMake(0, 1);
