搜索筛选器未在集合视图中更新.当我键入一个值 A 时，在搜索中键入另一个值后显示其资产

Question

//当我单击例如A的字母时，其数据来自服务器，但没有填写集合视图。当我单击字母 S 时，A 值资产正在填写集合 view.AS 当我从 AS 值中删除 A 时会显示值。//

@objc var filteredDataItems = Array((

@objc var searchCollectionList1 = NSMutableArray()

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String)
{
searchBar.barTintColor = UIColor.white
let lists:Array = searchCollectionList1 as Array
searchFilter(searchName: searchText)
filteredDataItems = lists
print(searchText)
self.collectionView.reloadData()
}

func updateSearchResults(for searchController: UISearchController)
{
searchController.searchBar.delegate = self
}

@objc func searchFilter(searchName:String)
{
self.searchCollectionList1.removeAllObjects()
let url = KsearchFilter + “appname=(kAppName)”
if self.debugPrint == true
{
print(“searchFilter--URL--SearchListViewController-----(url)-------------“)
}
let parameters = [“search”:searchName]

ApiManager.sharedManager.postDataWithJsonLambda(url: url, parameters: parameters)
{
(responseDict,error,isDone)in
// print(“responseDictresponseDict(String(describing: responseDict))“)
if self.debugPrint == true
{
print(“searchFilter--Response--SearchListViewController-----(String(describing: responseDict))-------------“)
}
if error == nil
{
let json = responseDict as! NSDictionary
if json[“statusCode”] != nil
{
let status = json[“statusCode”] as! Int
if status == 200
{
//self.updateSearchResults(for: UISearchController)
let result = json[“result”] as! NSArray
print(“Search result(result.count)“)
self.searchCollectionList1.addObjects(from: result as! [Any])
print(“searchCollectionList1(self.searchCollectionList1)“)
}
else
{
print(“json error status code not 200 getaccountInfo SearchListViewController”)
}
}
else
{
print(“json error getaccountInfo SearchListViewController”)
}
}
else
{
print(error?.localizedDescription ?? “getaccountInfo got with error”)
}
}
}

• 当我单击例如A的字母时，其数据来自服务器 但不填写集合视图。
• 当我点击字母S时，一个值 资产正在填充集合 view.AS 值显示 从 AS 值中删除 A。

你应该把你的重新加载相关的代码放在异步块中。

if status == 200
{           
let result = json[“result”] as! NSArray
print(“Search result(result.count)“)
self.searchCollectionList1.addObjects(from: result as! [Any])
print(“searchCollectionList1(self.searchCollectionList1)“)
DispatchQueue.main.async {
self.collectionView.reloadData()
}
}

现在，您可以在以下函数中注释此行

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String)
// YOUR EXISTING CODE HERE
// Comment the line to reload the collectionView, as we have already doing this in block.
//self.collectionView.reloadData()
}
