问题:

I have a problem with a navigation bar in iOS 11. I use this code:

[UINavigationBar appearance].prefersLargeTitles = YES;

...to set a new style for my app. It works well untill a user pull to refresh on the table view; then it breaks.

This is before pull-to-refresh:

Note: I use the table view controller's built-in pull-to-refresh control.

Thanks for the support :)
