Open lvyile opened 8 years ago

lvyile commented 8 years ago 
    UIImageView *currentImageView  = xxx // this is a iOS webp image
// then:
    UIImageWriteToSavedPhotosAlbum(currentImageView.image, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo;
{
// error is:
//There was a problem writing this asset because the write failed.
}

temp solution is :+1: 

    UIGraphicsBeginImageContextWithOptions(currentImageView.bounds.size, NO, 1.f);
    [currentImageView.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *uiImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
