iOS 中的股票蜡烛图？
我需要从头开始创建 Stock CandleStick 图表，因为我们对买入、卖出和持有信号有一些复杂的自定义。我现在已经准备好了所有数据，期待看到某种起点，我很了解 Object C，但在 iOS 平台上没有太多经验。有人可以推荐我一个好的网站或图书馆吗，提前谢谢。

我在过去的项目中使用过 core-plot。我认为还不错。它甚至有几个内置的股票图表预设。

I have used core-plot in past projects. I think its pretty good. It even has several built in pre-sets for stock graphs.
