I want to make a chart inside an UIView. Something like this:
Is there an easier way to draw the lines than using this method:
-(void)drawRect:(CGRect)rect{
[super drawRect:rect];
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor);
// Draw them with a 2.0 stroke width so they are a bit more visible.
CGContextSetLineWidth(context, 2.0f);
CGContextMoveToPoint(context, 0.0f, 0.0f); //start at this point
CGContextAddLineToPoint(context, 20.0f, 20.0f); //draw to this point
// and now draw the Path!
CGContextStrokePath(context);
}
?
Why don't you try UIBezierPath
a high-level implementation from Apple.
Simply refer UIBezierPath - Apple Doc for more info
You can try using UIBezierPath
class:
UIBezierPath *path = [UIBezierPath bezierPath];
[path moveToPoint:startPoint];
[path addLineToPoint:endPoint];
[path stroke];
If you need to draw a chart, try to use CorePlot - plotting framework.
