【问题描述】:
我正在尝试在 iOS 中创建一个搜索栏,并将其设置到过滤结果的位置,然后当您单击它时,它会显示一个复选标记。当我删除搜索文本时,复选标记消失并出现整页单元格,但我在搜索中选择的单元格未选择复选标记。有人可以修复下面的代码来帮助我吗?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSMutableSet *selectedUsers = [NSMutableSet set];
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
PFUser *user;
if (self.userResults != nil)
{
user = [self.userResults objectAtIndex:indexPath.row];
}
else
{
user = [self.allUsers objectAtIndex:indexPath.row];
}
cell.textLabel.text = user.username;
if ([selectedUsers containsObject:user])
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
if ([selectedUsers containsObject:user])
{
// user already selected
}
else
{
// select user
[selectedUsers addObject:user];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self.tableView deselectRowAtIndexPath:indexPath animated:NO];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryCheckmark;
PFRelation *friendsRelation = [self.currentUser relationforKey:@"friendsRelation"];
PFUser *user = [self.allUsers objectAtIndex:indexPath.row];
[friendsRelation addObject:user];
[self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
NSLog(@"Error %@ %@", error, [error userInfo]);
} }];
}
