点击搜索表格单元格时从未调用
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:@"Show Detail"])
{
Player *player = [self.fetchedResultsController objectAtIndexPath:[self.tableView indexPathForSelectedRow]];
[segue.destinationViewController setPlayer:player];
}
}
这会正确过滤列表,但在点击搜索表格单元格时,永远不会调用prepareForSegue。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Player Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == self.tableView)
{
// normal table view population
Player *player = [self.fetchedResultsController objectAtIndexPath:indexPath];
cell.textLabel.text = [[NSString alloc] initWithFormat:@"#%@ %@ %@", player.number, player.firstName, player.lastName];
cell.detailTextLabel.text = [[NSString alloc] initWithFormat:@"%@", player.position];
[cell.imageView setImageWithURL:[NSURL URLWithString:player.photo] placeholderImage:[UIImage imageNamed:@"playerplaceholder.jpg"]];
}
else if(tableView == self.searchDisplayController.searchResultsTableView)
{
// search view population
Player *player = [self.filteredFetchedResultsController objectAtIndexPath:indexPath];
cell.textLabel.text = [[NSString alloc] initWithFormat:@"#%@ %@ %@", player.number, player.firstName, player.lastName];
cell.detailTextLabel.text = [[NSString alloc] initWithFormat:@"%@", player.position];
[cell.imageView setImageWithURL:[NSURL URLWithString:player.photo] placeholderImage:[UIImage imageNamed:@"playerplaceholder.jpg"]];
}
return cell;
}

你需要把IF检查搜索是否有结果。 就像在这段代码中一样:
if ([[segue identifier]isEqualToString:@"ShowDetails"])
{
ShowDetailsViewController *sdvc = (ShowDetailsViewController *)[segue destinationViewController];
NSIndexPath *indexPath = [[self tableView] indexPathForSelectedRow];
Books *selectedBooks = nil;
if(self.searchDisplayController.active)
selectedBooks = (Books *)[[self searchResults]objectAtIndex:[[[[self searchDisplayController]searchResultsTableView]indexPathForSelectedRow]row]];
else
selectedBooks = (Books *)[[self fetchResultsController] objectAtIndexPath:indexPath];
sdvc.currentBooks = selectedBooks;
}
