UISearchDisplayController 和自定义单元格

Question

我在 UITableViewController 中实现了一个 UISearchDisplayController。搜索工作正常，但 UISearhDisplayController 使用标准单元格创建了一个新的 tableView，而我的 tableView 正在使用自定义单元格。另一个问题是我使用了segue：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 

并且 searchResultsTableView 中的单元格没有触发 segue..

如何使用自定义单元格和 segue 显示搜索结果？

这是代码：

...

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView == self.searchDisplayController.searchResultsTableView){ 
return [nameFilteredObj count];
} else {
return [sortedObj count];
}}

- (CustomCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"customCell";

CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil) {
cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == self.searchDisplayController.searchResultsTableView)
{
cell.textLabel.text = [[sortedObj objectAtIndex:indexPath.row] valueForKey:@"Name"];
 } else {
cell.nameLabel.text = [[sortedObj objectAtIndex:indexPath.row] valueForKey:@"Name"];
cell.countryLabel.text = [[sortedObj objectAtIndex:indexPath.row] valueForKey:@"Country"];
cell.bottleImageView.image = [UIImage imageNamed:[[sortedObj objectAtIndex:indexPath.row] valueForKey:@"Image"]];
} 
return cell; 
}

//The codes for filtering the results and update of searchResultsTableView (not necessary for this question I think):

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
[nameFilteredObj removeAllObjects];

for(NSDictionary *obj in sortedObj)
{
NSString *objName = [obj objectForKey:@"Name"];
NSRange range = [objName rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (range.location != NSNotFound) {
    [nameFilteredObj addObject:obj];
}}}

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString scope:
 [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
return YES;}

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption
{
[self filterContentForSearchText:[self.searchDisplayController.searchBar text] scope:
 [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]];
return NO;}
...

我使用 Storyboard 作为界面。

Answer 1

实际上很容易做到，但我在途中发现了许多复杂的半工作解决方案。使用这个简单的部分，SearchResultsTableView 就消失了：

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
...
self.searchDisplayController.searchResultsTableView.hidden=YES;
return YES;
}
