release版本运行报错

[Jvaeyhcd]

老郭，debug模式下正常，但是在release模式下报错
unsupported parameter combination: 8 integer bits/component; 16 bits/pixel; 1-component color space; kCGImageAlphaPremultipliedLast; 96 bytes/row.
报错代码：在UIImage＋BeeBeeExtension.m中：

• (UIImage *)grayscale
  {
  CGSize size = self.size;
  CGRect rect = CGRectMake(0.0f, 0.0f, self.size.width, self.size.height);

  CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceGray();
  CGContextRef context = CGBitmapContextCreate(nil,
  size.width,
  size.height,
  8,
  0,
  colorSpace,
  CGImageGetBitmapInfo(self.CGImage));

  BeeLog(@"size(%f,%f)",size.width,size.height);
  CGColorSpaceRelease(colorSpace);

  CGContextDrawImage(context, rect, [self CGImage]);
  CGImageRef grayscale = CGBitmapContextCreateImage(context);
  CGContextRelease(context);

  UIImage * image = [UIImage imageWithCGImage:grayscale];
  CFRelease(grayscale);

  return image;
  }
