gradient - NSGradient drawInBezierPath iOS equivalent -

is there ios equivalent - (void)drawinbezierpath:(nsbezierpath *)path angle:(cgfloat)angle?

i need draw gradient inside uibezierpath , cannot work. gradient draws on screen.

this example creates gradient inside uibezierpath in swift 3. draws slanting line green/white gradient.

import uikit  class drawingview: uiview {      override init(frame: cgrect) {         super.init(frame: frame)         self.isopaque = false     }      required init?(coder adecoder: nscoder) {         super.init(coder: adecoder)     }       override func draw(_ rect: cgrect) {         let startpoint = cgpoint(x:100, y:100)         let endpoint = cgpoint(x: 300, y:400)          let context = uigraphicsgetcurrentcontext()!         context.setstrokecolor(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0);         // create line         context.move(to: startpoint)         context.addline(to: endpoint)         context.setlinewidth(4)         // use line created above clipping mask         context.replacepathwithstrokedpath()         context.clip()          // create gradient         let locations: [cgfloat] = [ 0.0, 0.5 ]          let colors = [uicolor.green.cgcolor,                       uicolor.white.cgcolor]          let colorspace = cgcolorspacecreatedevicergb()          let gradient = cggradient(colorsspace: colorspace,                                   colors: colors cfarray, locations: locations)          let gradientstartpoint = cgpoint(x: rect.midx, y: rect.miny)         let gradientendpoint = cgpoint(x: rect.midx, y: rect.maxy)          context.drawlineargradient(gradient!,                                     start: gradientstartpoint, end: gradientendpoint,                                     options: .drawsbeforestartlocation)         uigraphicsendimagecontext()     }  }
