checkmark does not appear on first cell - ios

Question

i need to add checkmark when we tap on each cell, and it must show when i return back to tableview.
I tried with this code but its not working,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (self.thread == nil) {
cell.textLabel.text = #"Loading, please wait...";
} else if ([self.thread count] == 0) {
cell.textLabel.text = #"No Results!";
} else {
//
NSDictionary *msg = [self.thread objectAtIndex:indexPath.row];
NSLog(#"yourMutableDictionary - %#",msg);
if (indexPath.row == 0) {
cell.textLabel.text = [thread objectAtIndex:0];
} else {
cell.textLabel.text = [NSString stringWithFormat:#"%# ", [msg objectForKey:#"id"]];
if ([self.idSelected count] != 0) {
if ([self.idSelected containsObject:[NSString stringWithFormat:#"%#", [msg objectForKey:#"id"]]]) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
}
}
}
return cell;
}
#pragma mark - Table view delegate
//In a xib-based application, navigation from a table can be handled in - tableView:didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)path
{
if (self.thread == nil || self.thread.count == 0) {
return;
}
UITableViewCell *cell = [tableView cellForRowAtIndexPath:path];
if (path.row == 0) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;// this checkmark not working
}
else {
NSDictionary *user = [self.thread objectAtIndex:path.row];
NSString *uName = [NSString stringWithFormat:#"%# %#", [user objectForKey:#"first_name"], [user objectForKey:#"last_name"]];
NSString *uId = [NSString stringWithFormat:#"%#",[user objectForKey:#"id"]];
NSLog(#" click id%#", uId);
if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
[userNames removeObject:uName];
[userIds removeObject:uId ];
cell.accessoryType = UITableViewCellAccessoryNone; // this check mark is working perfectly
} else {
[userNames addObject:uName];
[userIds addObject:uId];
cell.accessoryType = UITableViewCellAccessoryCheckmark; // this check mark is working perfectly
}
}
}
first cell check mark is not working but others working perfectly. I want to add check mark on first cell too, how its possible

Answer 1

Use below code to display checkmark on multiple table view cell :
- (void)viewDidLoad
{
[super viewDidLoad];
self.arraySelectedCell = [NSMutableArray array];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([self.arraySelectedCell containsObject:indexPath])
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
// do here..
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
//the below code will allow multiple selection
if ([self.arraySelectedCell containsObject:indexPath])
{
[self.arraySelectedCell removeObject:indexPath];
}
else
{
[self.arraySelectedCell addObject:indexPath];
}
[tableView reloadData];
}
happy coding!
