我创建了一个包含自定义单元格的 TableView 控制器，并填充了来自 MySQL 数据库的数据。一切都很好。
我添加了一个搜索栏，搜索效果也很好。但是，当我选择搜索结果时，它会将我带到错误的详细视图（例如，我单击“Cookies”并将我发送到“Apples”的详细视图）。我的 .m 文件中是否缺少某些内容？这是我的代码：
.m
- (int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
return [searchResults count];
} else {
return [Strains count];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *strainTableIdentifier = @"StrainTableCell";
StrainTableCell *cell = (StrainTableCell *)[tableView dequeueReusableCellWithIdentifier:strainTableIdentifier];
if (cell == nil)
cell = [[StrainTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:strainTableIdentifier];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"StrainTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
if (tableView == self.searchDisplayController.searchResultsTableView) {
cell.titleLabel.text = [[searchResults objectAtIndex:indexPath.row] objectForKey:@"Title"];
cell.descriptionLabel.text = [[searchResults objectAtIndex:indexPath.row] objectForKey:@"Description"];
cell.ratingLabel.text = [[searchResults objectAtIndex:indexPath.row] objectForKey:@"Rating"];
NSLog(@"%@", searchResults);
} else {
cell.titleLabel.text = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Title"];
cell.descriptionLabel.text = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Description"];
cell.ratingLabel.text = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Rating"];
}
{
}
return cell;
}
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:@"SELF contains[cd] %@",
searchText];
searchResults = [Strains filteredArrayUsingPredicate:resultPredicate];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
StrainDetailViewController *detailViewController = [[StrainDetailViewController alloc]
initWithNibName:@"StrainDetailViewController" bundle:nil];
detailViewController.title = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Title"];
detailViewController.strainDetail = [Strains objectAtIndex:indexPath.row];
[self.navigationController pushViewController:detailViewController animated:YES];
}
