在searchTextDidChange将筛选结果给了Suggestions，但界面没有显示Suggestions，不知道是什么问题

属性设置以下这些

searchVC.delegate = self
searchVC.showHotSearch = false
searchVC.showSearchHistory = true
searchVC.searchHistoriesCount = 5
searchVC.hotSearchStyle = .colorfulTag
searchVC.searchHistoryStyle = .default
searchVC.searchViewControllerShowMode = .modeModal
searchVC.showSearchResultWhenSearchTextChanged = true
searchVC.showSearchResultWhenSearchBarRefocused = true
searchVC.hidesBottomBarWhenPushed = false
let NavSearchViewController = UINavigationController(rootViewController: searchVC)
self.present(NavSearchViewController, animated: true, completion: nil)

解决了，将searchVC.showSearchResultWhenSearchTextChanged = false就好了，我是直接删掉了，默认应该是false哈哈哈
