How to Set a tag Value in UITAbleView Cell and Pass It into URL in iOS?

Question

i am Newbie in iOS Development, i make an App that Contain UITableView I want to Set a Tag to UITableViewCell like as if it Was Selected then Cell tag is 1 else cell tag is 0 for that i Do Coding like as But it was always Set tag is equal 1 i want if cell was selected then tag is 1 else tag is equal to 0 Please Give me Solution for it.

Here my Code like as

in viewDidLoad

NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults];
SelectedRows = [NSMutableArray arrayWithArray:[userDef objectForKey:@"SelectedRows"]];

SelectedRows is NSMutableArray

-(CategoryCustumCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=@"Cell";
CategoryCustumCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
    NSArray *nib=[[NSBundle mainBundle]loadNibNamed:@"CategoryCustumCell" owner:self options:nil];
    cell=[nib objectAtIndex:0];
}
cell.categoryLabel.text=[self.categoryArray objectAtIndex:indexPath.section];

NSNumber *obj = [NSNumber numberWithInteger:indexPath.section];
if ([SelectedRows containsObject:obj])
{
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
    cell.tag=1;
    intValue=cell.tag;
    NSLog(@"Tag %d",intValue);
}
else
{
    cell.accessoryType = UITableViewCellAccessoryNone;
    cell.tag=0;
    NSLog(@"Tag %d",cell.tag);
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
CategoryCustumCell *cell = (CategoryCustumCell *)[tableView cellForRowAtIndexPath:indexPath];
NSString *selectedCell= cell.categoryLabel.text;
NSLog(@"Selected Cell Value %@",selectedCell);

NSNumber *obj = [NSNumber numberWithInteger:indexPath.section];
if ([SelectedRows containsObject:obj])
{
    [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryNone;
    [SelectedRows removeObject:obj];
    [tableView reloadData];
}else{
    [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;
    [SelectedRows addObject:obj];
    [tableView reloadData];
}

NSUserDefaults *userDef = [NSUserDefaults standardUserDefaults];
[userDef setObject:SelectedRows forKey:@"SelectedRows"];
[userDef synchronize];
}

And i Pass this Tag Value in Url Like as

NSURL *url=[NSURL URLWithString:[NSString stringWithFormat:@"http://www.janvajevu.com/webservice/insert_gcm.php?gcm_id=%@& category1=%d&category2=%d&category3=%d&category4=%d&category5 =%d&category6=%d&category7 =%d&category8=%d& category9=%d",uniqueIdentifier,intValue,intValue,intValue,intValue,intValue,intValue,intValue,intValue,intValue]];

Here i want tag Value 1 if cell was Selected and tag Value 0 if cell is not selected Please Give me Solution for it

Answer 1

The problem is that you're setting intValue to 1 in your cellForRowAtIndexPath: method:

if ([SelectedRows containsObject:obj])
{
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
    cell.tag=1;
    intValue=cell.tag;
    NSLog(@"Tag %d",intValue);
}

That's why intValue always equals 1.

And the solution is NOT to set the intValue equal to 0 in the other conditional of cellForRowAtIndexPath:. Although you're correctly setting your selected cells' tags to 1 and your unselected cells' tags to 0 as you intended, you shouldn't assign your intValue variable in this method. Instead, you should set your intValue depending on the current tag. For example, if there's a save button in each row, you'll want to set that button's tag to 0 or 1 then utilize the parameter in the the button press method to set intValue equal to sender.tag.

Edit: As was made clear in the comments "intValue,intValue,intValue,intValue,intValue,intValue,intValue,intValue,intValu‌​e" used in forming the url are actually supposed to be different numbers, each one representing a different cell's tag. But by using intValue repeatedly like that, you're actually using the same exact value 9 times. You actually need to use 9 different values to do what you're attempting to do.

You can create an array of those 9 values dynamically in cellForRowAtIndexPath:.

In viewDidLoad you can initialize a class NSMutableArray variable with exactly 9 indexes all containing 0:

self.tagArray = [[NSMutableArray alloc] init];
for (int i = 0 ; i < 9 ; i ++) {
    [self.tagArray addObject:[NSNumber numberWithInt:0]];
}

Then update those indices in cellForRowAtIndexPath::

-(CategoryCustumCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // ...

    NSNumber *obj = [NSNumber numberWithInteger:indexPath.section];
    if ([SelectedRows containsObject:obj])
    {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        cell.tag=1;
    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
        cell.tag=0;
    }

    [self.tagArray replaceObjectAtIndex:indexPath.section withObject:[NSNumber numberWithInteger:cell.tag]];
    return cell;
}

Then during perform save, use the tags stored in your tag array:

- (void)performSave {

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.janvajevu.com/webservice/insert_gcm.php?gcm_id=%@&category1=%@&category2=%@&category3=%@&category4=%@&category5=%@&category6=%@&category7=%@&category8=%@&category9=%@", uniqueIdentifier, self.tagArray[0], self.tagArray[1], self.tagArray[2], self.tagArray[3], self.tagArray[4], self.tagArray[5], self.tagArray[6], self.tagArray[7], self.tagArray[8]]];    
}
