Question

我正在使用filterContentForSearchText搜索表格视图。搜索效果很好但是当我选择一行时，我会将该行的ID发送到目标视图控制器。当我进行搜索时，它仍会在我搜索之前发送该行的ID。我完全理解问题是什么，但我无法弄清楚如何解决它。这就是我到目前为止所做的：

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

    searchResults = [[projectArray valueForKey:@"clientName"] filteredArrayUsingPredicate:resultPredicate];
}

和

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"CategorySegue"]) {
    TimeCategoryViewController *dvc = [segue destinationViewController];

    if ([self.searchDisplayController isActive]) {
        NSIndexPath *path = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
        NSNumber *pid = [[projectArray objectAtIndex:path.row] valueForKey:@"pid"];


        dvc.selectedProject = [searchResults objectAtIndex:pid];
    } else {
        NSIndexPath *path = [self.tableView indexPathForSelectedRow];
        NSNumber *pid = [[projectArray objectAtIndex:path.row] valueForKey:@"pid"];
        dvc.selectedProject = pid;
    }
}

是否有一种简单的方法可以将ID添加到搜索结果中，以便将其传递给dvc？

问题是searchResults仅包含每个对象的“clientName” 而不是“完整信息”。我建议searchResults为projectArray的“子阵列”：

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
    NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"clientName CONTAINS[cd] %@", searchText];
    searchResults = [projectArray filteredArrayUsingPredicate:resultPredicate];
}

然后，您可以访问projectArray中的searchResults或prepareForSegue：

if ([self.searchDisplayController isActive]) {
    NSIndexPath *path = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
    NSNumber *pid = [[searchResults objectAtIndex:path.row] objectForKey:@"pid"];
    dvc.selectedProject = pid;
} else {
    NSIndexPath *path = [self.tableView indexPathForSelectedRow];
    NSNumber *pid = [[projectArray objectAtIndex:path.row] objectForKey:@"pid"];
    dvc.selectedProject = pid;
}

（当然，您还需要将cellForRowAtIndexPath调整为此更改。）
