在iPhone SDK中绘制图形的Core-Plot有哪些替代方案

If what you intend to draw is relatively easy, you may get quick results by using Quartz and drawing the graph yourself. Just subclass an UIView and override its drawRect: method.

如果您打算绘制的内容相对简单，可以使用Quartz并自己绘制图形来获得快速结果。只需子类化UIView并覆盖其drawRect：方法。

A very, very simple example of drawing a square, 10x50 pixels at a fixed position, via Quartz:

一个非常非常简单的例子，通过Quartz在固定位置绘制一个10x50像素的正方形：

- (void) drawRect:(CGRect)rect
{
    CGContextRef ctx = UIGraphicsGetCurrentContext();
    CGColorRef red = [[UIColor redColor] CGColor];

    CGRect barRect = CGRectMake(10.f, 20.f, 10.f, 50.f);
    CGContextSetFillColorWithColor(ctx, red);
    CGContextFillRect(ctx, barRect);
}

Since the OP asked his questions, there has been an abundance of new chart libraries. GraphKit, TWRCharts, to name only two. CocoaControls lists a lot more, if you do a search for 'graph'. So I'd like to gather more feedback with regards to this question.

由于OP提出了他的问题，因此有大量新的图表库。 GraphKit，TWRCharts，仅举两例。如果你搜索'graph'，CocoaControls列出了更多。所以我想就这个问题收集更多反馈意见。
