CGRect newBounds = self.tableView.bounds;
newBounds.origin.y = newBounds.origin.y + self.searchBar.bounds.size.height;

newBounds.origin.y = newBounds.origin.y + self.searchBar.bounds.size.height;
应该是
newBounds.origin.y = newBounds.origin.y + self.searchController.searchBar.bounds.size.height;
而不是self.searchBar,它需要是self.searchController.searchBar刚刚解决了这个问题。下面的说法是错误的
