updateSearchResults()没有被调用

问题描述:

我读过类似的问题和解决方案。但似乎没有解决我的问题。我正在使用自定义搜索控制器和自定义搜索栏和func updateSearchResults(对于searchController:UISearchController)没有被调用。updateSearchResults()没有被调用

var customSearchController: CustomSearchViewController! 

CustomSearchViewController:在viewDidLoad中()

customSearchController = CustomSearchViewController(searchResultsController: ***nil***, searchBarFrame: CGRect(x: 0.0, y: 0.0, width: searchTableView.frame.size.width, height: 44.0), searchBarFont: UIFont(name: "HelveticaNeue", size: 16.0)!, searchBarTextColor: UIColor.purple, searchBarTintColor: UIColor.white) 

customSearchController.searchResultsUpdater = self 
customSearchController.definesPresentationContext = true 
customSearchController.customSearchBar.placeholder = "What are you looking for?" 
customSearchController.customSearchBar.backgroundColor = UIColor.white 
customSearchController.customSearchBar.sizeToFit() 
customSearchController.customSearchBar.resignFirstResponder() 
customSearchController.customSearchBar.showsCancelButton = true 
customSearchController.customSearchBar.delegate = self 

没有得到所谓::(

func updateSearchResults(for searchController: UISearchController) { 
    filtered.removeAll() 
    filtered = searchArray.filter({ (text) -> Bool in 
     let tmp: NSString = text as NSString 
     let range = tmp.range(of: customSearchController.customSearchBar.text!, options: NSString.CompareOptions.caseInsensitive) 
     return range.location != NSNotFound 
    }) 
    self.searchTableView.reloadData() 
} 

挣扎小时后,我能够通过使用来解决它: FUNC搜索栏(_ searchBar:UISearchBar,textDidChange searchText:String) - UISearchBarDelegate委托方法。

而不是updateSearchResults() - UISearchResultsUpdating委托方法

希望它可以帮助某人:)
