使用S7GraphView时无法正常工作

Question

我想在iphone中绘制一个折线图，并且正在使用S7GraphView。但是当我编译我的应用程序时，它显示了很多错误，如：

"CGContextSetFillColorWithColor", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextFillRect", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextSetLineDash", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextSetLineWidth", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextMoveToPoint", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextAddLineToPoint", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextClosePath", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextSetStrokeColorWithColor", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextStrokePath", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o
  "_CGContextFillPath", referenced from:
      -[S7GraphView drawRect:] in S7GraphView.o

有人能帮助我吗？

尝试将您的应用与Quartz.framework和/或QuartzCore.framework相关联。
