searchDisplayController' 已弃用：首先在 iOS 8.0 中弃用

Question

这是我的代码：需要删除我的警告。我在 iOS 9

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{

    if (searchText.length>0) {

        self.searchBarActive = YES;



[self filterContentForSearchText:searchText scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
                                                   objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];

        [self.collectionView reloadData];
    }else{
        // if text lenght == 0
        // we will consider the searchbar is not active
        self.searchBarActive = NO;
    }



}

需要删除我在 question.It 中提到的警告应该适用于上述 iOS 7. 我是 ios 的新手。但是需要删除我的警告消息。我已经尝试了以下代码：

if([UISearchController class]){
//Create an UISearchController and add it to your UITableViewController
}else{
//Create an UISearchDisplayController and add it to your UITableViewController 
}

但说真的，我不知道如何实现它。如果有人帮助我解释代码，将有助于我进一步了解 move.Thanks @@

Answer 1

.h

@property (strong, nonatomic) UISearchController *searchController;

.m

[self filterContentForSearchText:searchText scope:[[self.searchController.searchBar scopeButtonTitles] objectAtIndex:[self.searchController.searchBar selectedScopeButtonIndex]]];

此编码运行良好....
