我正在尝试将一个添加UISearchBar
到我在“nib”文件中定义的表格视图中。我在 IB 中添加了一个搜索栏和搜索显示控制器,链接了搜索栏插座,并将其添加到视图控制器的“.h”文件中:
@interface SearchListViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate, UISearchDisplayDelegate>
此外,我还实现了以下委托方法:
- (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;
}
我发现shouldReloadTableForSearchString:
调用了该方法,但是shouldReloadTableForSearchScope:
从未调用过方法,因此我的表格视图数据没有重新加载搜索结果......我会丢失什么?
