ios 中使用 Search Display Controller 來對 UITableView 進行前台查詢

1. 使用  Search Display Controller  控制項 

2. 實現

   UISearchDisplayDelegate

3. 定義全部的table的資料和 過濾後的資料，以及過濾標記

   @property (strong,
   nonatomic) NSArray *arOriginal;

   @property (strong,
   nonatomic) NSArray *arFiltered;

   @property (readwrite,
   nonatomic) BOOL isSearching;

4. 在 過濾輸入框啟用調用中 實現 

   - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {    if(self.searchDisplayController.searchBar.text.length>0) {        self.isSearching=YES;        NSString *strSearchText = self.searchDisplayController.searchBar.text;        NSMutableArray *ar=[NSMutableArray array];        // correctly working ! Thanx for watching video !        for (NSDictionary *d in self.arOriginal) {            NSString *strData = [d valueForKey:@"name"];            if([strData rangeOfString:strSearchText].length>0) {                [ar addObject:d];            }        }        self.arFiltered=[NSArray arrayWithArray:ar];    } else {        self.isSearching=NO;    }    return YES;}

5. 在顯示每個cell的時候實現

   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{    static NSString *CellIdentifier = @"Cell";        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];    if (cell == nil) {        cell = [[[NSBundle mainBundle] loadNibNamed:@"CCell" owner:self options:nil] objectAtIndex:0];    }    NSDictionary *dToAccess = (self.isSearching)?[self.arFiltered objectAtIndex:indexPath.row]:[self.arOriginal objectAtIndex:indexPath.row];        [(UILabel*)[cell viewWithTag:1] setText:[dToAccess valueForKey:@"name"]];    [(UILabel*)[cell viewWithTag:2] setText:[dToAccess valueForKey:@"price"]];    return cell;}
