PhotoKit: Crash [assetsd was interrupted or died] when using requestImageForAsset to fetch asset with PHImageManagerMaximumSize

Vote count:

I am trying to display Image using UIPageViewController, using the sample code from apple and replacing it with the new photo Kit: PHAsset http://ift.tt/1m3vb8u When i swiping the photo with PHImageManagerMaximumSize, i found that after 50 photos, the app will crash showing "assetsd interrupted or died". But if i request a smaller target size(same size as screen), the crash is becoming unlikely. I am wondering if it is a memory leak somewhere in my app or there is something wrong in the rendering system ? Seems the compression and uncompression are using a lot of pages. Could anyone help me to have a look?

- (void)displayImage:(PHAsset*)asset
{
 [self.imageView removeFromSuperView]
 self.imageView = nil;
 [[PHImageManager defaultManager] requestImageForAsset:asset targetSize:PHImageManagerMaximumSize contentMode:PHImageContentModeAspectFit options:nil resultHandler:^(UIImage *result, NSDictionary *info) {

        self.imageView = [[UIImageView alloc] initWithImage:result];
        self.imageView.contentMode = UIViewContentModeScaleAspectFit;
        // self is a scrollView    
        [self addSubview:self.imageView];
    }];
}
