How to use NSPointArray?

So I want to use the method appendBezierPathWithPoints:count: in NSBezierPath. But the method requires me to use NSPointArray. The documentary doesn't really talk much about it and all I could get about it is that it's an array of NSPoints and I'm not sure how to do it. I think that it uses the c array mechanism, but I'm not sure.

Thanks.

Solution

  • Yes, you need a C-style array of points to pass to appendBezierPathWithPoints:count:. For example you might do something like this:

    NSPoint pointArray[3];

pointArray[0] = NSMakePoint(0, 0);
pointArray[1] = NSMakePoint(0.5, 0.25);
pointArray[2] = NSMakePoint(1, 1);

[lines appendBezierPathWithPoints:pointArray count:3];

    where lines is an instance of NSBezierPath.

    In a more complicated case you'll use a variable number of points say.
