Programmatic beginRefreshing() on iOS11 has problems with largeTitles mode
问题 We have found what seems to be a bug in UIKit but wanted to post here to see if anyone else has this problem or found a solution. We're trying to use the new iOS11 large titles and hoisted search bar/refreshcontrol. We seemed to have found a problem where the root viewController of the navigation stack shows a minor display issue (problem A) but once another viewcontroller is pushed onto the navigation stack, the display goes nuts (problem B): Things to note: The problem is worse on the 2nd
