ios – CGPathCreateCopyByTransformingPath到Swift 3

概述我是 Swift 3的新手,我正在尝试将该函数转换为Swift 3： - (void) drawRect: (CGRect)rect{ if (self.editionMode == Zoom) { for (Area *area in self.mArrayPaths) { CGAffineTransform zoom = CGAffineT 我是 Swift 3的新手,我正在尝试将该函数转换为Swift 3：

- (voID) drawRect: (CGRect)rect{    if (self.editionMode == Zoom) {        for (Area *area in self.mArrayPaths) {            CGAffinetransform zoom = CGAffinetransformMakeScale(self.scale,self.scale);            CGPathref movedpath = CGPathCreatecopyBytransformingPath([area.pathArea CGPath],&zoom);            area.pathAreatransformed = [UIBezIErPath bezIErPathWithCGPath:movedpath];            [area.fillcolor setFill];            [area.strokecolor setstroke];            [area.pathAreatransformed fill];            [area.pathAreatransformed stroke];        }    }    else if (self.editionMode == MoveShapes) {        [self.currentArea.fillcolor setFill];        [self.currentArea.pathAreaShift fill];        [self.currentArea.pathAreaShift stroke];        for (Area *area in self.mArrayPaths) {            if (area == self.currentArea) {                continue;            }            [area.fillcolor setFill];            [area.strokecolor setstroke];            [area.pathArea fill];            [area.pathArea stroke];        }    } else {        [self.currentArea.fillcolor setFill];        [self.currentArea.pathArea fill];        [self.currentArea.pathArea stroke];        for (Area *area in self.mArrayPaths) {            [area.fillcolor setFill];            [area.strokecolor setstroke];            [area.pathArea fill];            [area.pathArea stroke];        }    }}

到目前为止我已经做了这个,但我没有能够翻译这部分：

CGAffinetransform zoom = CGAffinetransformMakeScale(self.scale,self.scale);    CGPathref movedpath = CGPathCreatecopyByTransImformingPath([area.pathArea CGPath],&zoom);    area.pathAreatransformed = [UIBezIErPath bezIErPathWithCGPath:movedpath];

我是这样的：

overrIDe func draw(_ rect: CGRect) {    if self.editionMode == EditionMode.Zoom {        for area in self.mArrayPaths {            if let area = area as? Area {                var zoom: CGAffinetransform = CGAffinetransform.init(scaleX: self.scale,y: self.scale)                var movedpath = CGPath.copy(using: &zoom)                if let movedpath = movedpath {                    area.pathAreatransformed = UIBezIErPath(cgPath: movedpath)                }            }        }    }}

我收到此错误：

Ambiguous reference to member ‘copy(dashingWithPhase:lengths:transform
