I have just created a path using NSBezierPath and did [path fill] to draw it onto the view. My question is how do I remove what I have drawn?
One possible solution is to use [path fill] again with the background color but this will not work if there is a background image instead of a simple background color. So anyone has any ideas?
해결책
Just remove the path from path array and call the drawRect again. btw mai know in which you are storing the paths, mutable array or dictionary?
다른 팁
The path you created is displayed when you set a CALayer path
view.layer.path = path.CGPath;
To clear that path
view.layer.path = nil;
