ios - GameOver screen position swift -

i have implemented game on screen pop when player loses, height in middle of screen images stretches edge of screen don't want do. want image offset screen slightly. have attached code game on screen below. height set need setting width.

    gameoverscreen = skspritenode(texture: gameoverscreentexture)      gameoverscreen.position = cgpoint(x: self.frame.midx, y: self.frame.midy)      gameoverscreen.size.height = self.frame.height / 3      gameoverscreen.zposition = 0      self.addchild(gameoverscreen) 

managed sort out. changed line:

  gameoverscreen = skspritenode(texture: gameoverscreentexture) 

to this:

gameoverscreen = skspritenode(texture: gameoverscreentexture, size: cgsize(width: 600, height: 600))
