在category的{​​{1}}下方使用

UIImage

---

@interface UIImage (Utitlities)
  -(UIImage*)redEyeCorrection;
@end

用法：下面给出的示例代码

@implementation UIImage (Utitlities)
  -(UIImage*)redEyeCorrection
  {
    CIImage *ciImage = [[CIImage alloc] initWithCGImage:self.CGImage];

    // Get the filters and apply them to the image
    NSArray* filters = [ciImage autoAdjustmentFiltersWithOptions:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:NO] forKey:kCIImageAutoAdjustEnhance]];
    for (CIFilter* filter in filters)
    {
      [filter setValue:ciImage forKey:kCIInputImageKey];
      ciImage = filter.outputImage;
    }

    // Create the corrected image
    CIContext* ctx = [CIContext contextWithOptions:nil];
    CGImageRef cgImage = [ctx createCGImage:ciImage fromRect:[ciImage extent]];
    UIImage* final = [UIImage imageWithCGImage:cgImage];
    CGImageRelease(cgImage);
    return final;
  }
@end
