UITableView 和 SearchBarController 视图 iPhone

Question

我的表格视图在这个用户界面中：

但是当我开始搜索时，视图会更改为：

我希望当用户开始搜索时，视图应该与我为不同字段使用的标题相同，例如标题应该存在并且搜索的数据应该显示在其位置的相同标题下？

有可能吗？

我正在使用此代码：

在 viewDidLoad 中：

// create a filtered list that will contain products for the search results table.
//filteredListItems = [NSMutableArray arrayWithCapacity:[listItems count]];
filteredListItems = [[NSMutableArray alloc] initWithCapacity:[self.listVehicles count]];

// restore search settings if they were saved in didReceiveMemoryWarning.
if (self.savedSearchTerm){
    [self.searchDisplayController setActive:self.searchWasActive];
    [self.searchDisplayController.searchBar setSelectedScopeButtonIndex:self.savedScopeButtonIndex];
    [self.searchDisplayController.searchBar setText:savedSearchTerm];

    self.savedSearchTerm = nil;
}

[listTable reloadData];

然后是另一种方法：

-(void)viewDidDisappear:(BOOL)动画{

self.searchWasActive = [self.searchDisplayController isActive];
self.savedSearchTerm = [self.searchDisplayController.searchBar text];
self.savedScopeButtonIndex = [self.searchDisplayController.searchBar selectedScopeButtonIndex];}

在搜索栏方法中：

//search bar implementation
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope{        
NSPredicate *resultPredicate = [NSPredicate 
                                predicateWithFormat:@"SELF contains[cd] %@",
                                searchText];

self.filteredListItems = [self.listVehicles filteredArrayUsingPredicate:resultPredicate];}

- (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 YES;}

谢谢

你应该实现 UISearchBar without(!!!) SearchDisplayController。转到您的 xib 文件，如果您在右侧选项卡中搜索“搜索栏”，您将获得 2 个结果。您应该只将搜索栏加入您的项目。

另一种解决方案，只需返回 NO：

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