數據重複使用searchbarcontroller篩選

Question

我使用searchbarcontroller篩選tableview數據，一切工作正常，但問題是相同的數據在篩選器上重複使用searchbarcontroller tableview。

喜歡：假設如果字母的列表被顯示在所述的tableview（A，B，C，d）tableViewCells然後當我在此的tableview然後(tableView == self.searchDisplayController.searchResultsTableView)是用於searchbarcontroller示出了數據以重複方式

喜歡：如果我正在搜索searchResultTableView在tableViewCells上顯示（A，A，A，A，A，A）。

但是在正常的tableview數據顯示正常沒有重複的數據。

任何人都請告訴我我的代碼中的實際問題在哪裏。

在此先感謝。

使用謂詞使用數組

NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"SELF contains[c] 'e'"]; 
    [array filterUsingPredicate:sPredicate]; 

或

它顯示沒有重複

NSArray *beginArray = [filteredArray filteredArrayUsingPredicate: 
    [NSPredicate predicateWithFormat: 
    @"self BEGINSWITH[cd] %@", searchText]]; 
NSArray *anyArray = [filteredArray filteredArrayUsingPredicate: 
    [NSPredicate predicateWithFormat: 
    @"self CONTAINS[cd] %@", searchText]]; 

NSMutableArray *resultArray = [NSMutableArray arrayWithArray:beginArray]; 
for (id obj in anyArray) { 
    if (![resultArray containsObject:id]) { 
     [resultArray addObject:id]; 
    } 
} 
filteredArray = resultArray;
