I think I'm having a similar problem, but I'm not sure SDWebImage is the culprit.

I have a custom UITableViewCell subclass. In it I have a UIImageView which is embedded in a UIView that is used as a coloured background to the image.

When I attempt to configure the cell, either in cellForRowAtIndexPath: or in willDisplayCell: the initial size of the subviews is shown as 1000x1000. I try to set an image into the image view using [self.iconView sd_setImageWithURL:iconURL placeholderImage:placeholder]; I also set a background colour of the enclosing UIView.

The result is that the image does not get set and even the background colour of the UIView does not get set until the cells are dequeued a second time, either by scrolling or switching to a different view.

It seems like the cells are not ready to be configured. I bet it's a quirk of iOS 10, but man is it annoying.

Edit:
This Stack Overflow response seems to offer some insight.

If you are using clipsToBounds/maskToBounds then it doesn't seem to work properly.

Just call this method [self.iconView layoutIfNeeded] before make it circle.

If you're going to add code that accesses the layers of the such as adding a corner radius you can add that code into the cell's -layoutSubviews method and everything should work.

It seems that accessing the layer, or at least settings masksToBound=YES from inside willDisplayCell: or cellForRowAtIndexPath: will cause the image view to not load properly on the first pass. Putting it in -layoutSubviews works.

I spent three days of development trying to figure out why my image was not setting after it loaded using the SDCompletionBlock. After tried and true testing - Calling a setNeedsLayout - layoutIfNeeded - even manually updating the ReusableHeaderView for my collectionView using a layout context; @tylerjames answer did the trick. Unsure if this is an xCode bug or if this is by design, but changing my sublayer work (cornerRadius - contentMode) from my cellForRow to layoutSubviews did the trick. Thanks for a helpful thread guys. PS. SDWebImg is a rockstar.
