我显然还不熟悉Xcode。在iOS 8中,SeacrhDisplayController
已经被弃用了,而我不知道如何在tableview上实现UIsearchController
。
我已经搜索过相关内容了,但是并没有找到特别清晰的教程。
这是我用于SearchDisplayController
的代码:
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
return [searchResults count];
} else {
return [categories count];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"FirstTableCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
if (tableView == self.searchDisplayController.searchResultsTableView) {
cell.textLabel.text = [searchResults objectAtIndex:indexPath.row];
} else {
cell.textLabel.text = [categories objectAtIndex:indexPath.row];
}
cell.imageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
[self performSegueWithIdentifier: @"showArrayDetail" sender: self];
}
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"showArrayDetail"]) {
SecondViewController *destViewController = segue.destinationViewController;
NSIndexPath *indexPath = nil;
if ([self.searchDisplayController isActive]) {
indexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
destViewController.categoryName = [searchResults objectAtIndex:indexPath.row];
} else {
indexPath = [self.tableView1 indexPathForSelectedRow];
destViewController.categoryName = [categories objectAtIndex:indexPath.row];
}
}
}
