Image disappears

[drshane]

Image disappears when UIActivityViewController is called on screen in iOS 11. Changing it to a UIImageView does not disappear.

i met with this problem a few days ago. try change this methods
- (void)setProcessedImageInternal:(UIImage *)processedImage { [self willChangeValueForKey:@"processedImage"]; _processedImage = processedImage; super.image = processedImage; self.layer.contentsScale = processedImage.scale; self.layer.contents = (id)_processedImage.CGImage; [self didChangeValueForKey:@"processedImage"]; }

and

- (void)setUp { self.shadowColor = [UIColor blackColor]; _crossfadeDuration = 0.25; super.contentMode = UIViewContentModeCenter; }
