Search and Checkmarks in tableViews - ios

Question

I am trying to make a search bar in iOS and have made it to where it filters results and then when you click on it, it shows a checkmark. When I delete the search text, the check mark goes away and the full page of cells appears but the cell that I selected in the search is not selected with a check mark. Can someone please fix the code below to help me?
- (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]);
} }];
}

}
else
{

}
if (cell.accessoryType == UITableViewCellAccessoryCheckmark)
{
cell.accessoryType = UITableViewCellAccessoryNone;
[selectedUsers removeObject:user1];
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
[selectedUsers addObject:user1];
}
}
See if this helps.

The thing is that when you close the search bar the table view is reloaded.this time you have to record all the cells index path that user select.That is you do it in didSelectRowAtIndexPath delegate Method,and save in an array value that user select.
and in cellForRowAtIndexPath you can check all the cell whose indexPath in in the array.
Hope you got it...

NSMutableArray *array=[[NSMutableArray alloc]init];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { if
([selectedBillsArray containsObject:indexPath]) {
cell.accessoryType=UITableViewCellAccessoryCheckmark; }
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell= [tableView cellForRowAtIndexPath:indexPath];
if (cell.accessoryType==UITableViewCellAccessoryCheckmark)
{
[cell setAccessoryType:UITableViewCellAccessoryNone];
[selectedBillsArray removeObject:[NSString stringWithFormat:#"%i",indexPath];
}
else
{
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
[selectedBillsArray addObject:[NSString stringWithFormat:#"%i",indexPath];
}
}
Do something like this...
