Draw Border around UIImage

I am needing a border around a UIImage. The UIImage is added to a PDF file. Here is the code for drawing the image currently.

- (void) drawImage2
{
    UIImage * demoImage = self.imageCopy;
    NSData *jpegData = UIImageJPEGRepresentation(demoImage, 0.80);
    CGDataProviderRef dp = CGDataProviderCreateWithCFData(( CFDataRef)jpegData);
    CGImageRef cgImage = CGImageCreateWithJPEGDataProvider(dp, NULL, true, kCGRenderingIntentDefault);
    [[UIImage imageWithCGImage:cgImage] drawInRect:CGRectMake(513, 314, 135, 135)];  
}

Any suggestions for how I can do this? I know how to do it using CALayers with a UIImageView, but not sure here since I don't have the view.

- (UIImage*)imageWithBorderFromImage:(UIImage*)source;
{
  CGSize size = [source size];
  UIGraphicsBeginImageContext(size);
  CGRect rect = CGRectMake(0, 0, size.width, size.height);
  [source drawInRect:rect blendMode:kCGBlendModeNormal alpha:1.0];

  CGContextRef context = UIGraphicsGetCurrentContext();
  CGContextSetRGBStrokeColor(context, 1.0, 0.5, 1.0, 1.0); 
  CGContextStrokeRect(context, rect);
  UIImage *testImg =  UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();
  return testImg;
}
