YYCGImageCreateWithWebPData decode animated webp #58

Open PhilCai1993 opened 8 years ago

@implementation UIImage (WebP)

+ (UIImage *)xx_imageWithWebPData:(NSData *)data {
  CFDataRef dataRef = (__bridge CFDataRef)data;
  YYImageType type = YYImageDetectType(dataRef);
  NSInteger frameCount = YYImageGetWebPFrameCount(dataRef);
  CGImageRef cgImageRef = YYCGImageCreateWithWebPData(dataRef, YES, NO, NO, NO);
  NSLog(@"type = %d, frameCount = %d", type, frameCount);
  UIImage *image = [UIImage imageWithCGImage:cgImageRef];
  return image;
}

@end

如果data是animated webp, YYCGImageCreateWithWebPData生成的image该怎么生成动态的UIImage呢？

That UIKit suck API(+[UIImage animatedImageWithImages:duration:) so I must use this hack to create _UIAnimatedImage.
