Get the UIBezierPath or CGPath from CGContextRef

Question

I have a bezier path inside the current graphics context that I want to store as a UIBezierPath or CGPath. Do you know how to get the path out of a CGContextRef?

Answer 1

You can copy the context's current path using CGContextCopyPath .

There is no function that copies the clipping path. Indeed, the clipping region won't be defined by a path if you've used CGContextClipToMask .

Answer 2

您可以使用CGContextCopyPath函数：

CGPathRef myPath = CGContextCopyPath(context);

Answer 3

Swift 4.0 and higher

You can just use for coping the path.

let copy = context.path
