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;
  }
