Question

I am building a drawing application (something like MiniDraw).
UIBezierPath class is cool for that and I can accomplis dynamic path building:

[path addCurve:23.0 controlPoint:5.5]; //etc...

When I finish I want the ability to change the points in that path without creating a new UIBezierPath, that way I could accomplish dynamic editing of path.

For example, FabricJS javascript library can do this in a way that each path object contains array structure like this:

[['M', 20, 20], ['L', 40, 40], ['Q', 70, 50, 30], ['Z']] //etc...

That way I can edit each point but I don’t see anything similar in UIBezierPath class.

Answer 1

UIBezierPath does not allow your to change points already added to the path. You will have to create a new path.
