利用 CAShapeLayer + UIBezierpath 写的K线图Demo.
//分时线的创建方法
FLTimeChartView *timeChartView = [[FLTimeChartView alloc]initWithFrame:CGRectMake(0, 0, CGRectGetWidth(frame), CGRectGetHeight(frame) * 0.75 - 20) StockGroupModel:self.stockModelArray];
[self.view addSubview:timeChartView];
//分时线开始绘制
[self.timeChartView startDrawTimeChart];//k线的创建方法
FLKLineChartView *kLineChartView = [[FLKLineChartView alloc]initWithFrame:CGRectMake(0, 0, CGRectGetWidth(frame), CGRectGetHeight(frame) * 0.75 - 20)];
self.kLineChartView.delegate = self;
[self.view addSubview:kLineChartView];
//设置数据
[kLineChartView setKLineChartWithModel:self.stockModelArray];
//k线开始绘制
[self.kLineChartView drawKLineChart];//副图-指标
FLAccessoryChartView *accessoryChartView = [[FLAccessoryChartView alloc]initWithFrame:CGRectMake(0, CGRectGetHeight(frame) * 0.75, CGRectGetWidth(frame), CGRectGetHeight(frame) * 0.25)];
[self.view addSubview:accessoryChartView];
//设置需要绘制的model - 直接绘制
[accessoryChartView setAccessoryChartDataSource:needDrawModels];
