Try by getting a screenshot of your MyLineDrawingView:

- (UIImage*)takeSignatureImage{
  UIGraphicsBeginImageContext(drawScreen.bounds.size);    
  [drawScreen.layer renderInContext:UIGraphicsGetCurrentContext()];
  UIImage *signatureImage = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();  
  return signatureImage;
}

-(IBAction)onOKButtonClick{
   UIImage *signatureImg=[self takeSignatureIamge];
   if(signatureImg){
      yourImageView.image=signatureImg;
   }
}

An make sure to keep drawScreen as instance variable.
