UITableViewCell reuse good practice

Question

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {


    static NSString *CellIdentifier = @\"NotificationViewC         


        

Answer 1

I usually separate the creation and configuration of the cell into two logical parts:

1. Create the cell and set up all its properties that are the same for every single cell (i.e. layout, layer)
2. Write a separate -(void)configureCell:(UITableViewCell*)cell; function where I set up everything specific for a particular cell from the datasource (i.e. values of labels and imageView).

Then in cellForRowAtIndexPath:

-(UITableViewCell *)tableView:(UITableView *)tableView 
        cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
    static NSString *CellIdentifier = @"NotificationViewCell";
    CardViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell==nil){
       [self createCell:&cell];
    }

    Mercant* mercantList = [self.cardListArr objectAtIndex:indexPath.row];

    [self configureCell:cell withMercant:mercantList];

    return cell;
}

-(void)createCell:(CardViewCell**)cellPtr
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CardViewCell" 
                                                 owner:self 
                                               options:nil];
    *cellPtr = [nib objectAtIndex:0];

    CardViewCell* cell = *cellPtr;

    cell.contentView.backgroundColor=[UIColor clearColor];
    [ModelClass addSublayer:cell.contentView];

    cell.cellbg.layer.cornerRadius = 8;
    cell.cellbg.layer.masksToBounds = YES;

    cell.cellbg.layer.borderWidth = 1;
    cell.cellbg.layer.borderColor = [[UIColor grayColor] CGColor];


    cell.logoImage.layer.cornerRadius = 8;
    cell.logoImage.layer.masksToBounds = YES;

    cell.logoImage.layer.borderWidth = 1;
    cell.logoImage.layer.borderColor = [[UIColor grayColor] CGColor];
}

-(void)configureCell:(CardViewCell*)cell withMercant:(Mercant*)mercantList
{
    cell.nameLab.text=merchantList.name;

    NSLog(@"merchantList.myloyalty.points=%@",merchantList.myloyalty.points);
//    NSLog(@"memberNO=%@",merchantList.myloyalty.memberNO);
    cell.integralLab.text=[NSString stringWithFormat:NSLocalizedString(@"points_dot", @"") ,[merchantList.myloyalty.points intValue]];


    cell.cardNumberLab.text=[NSString stringWithFormat:@"%@%@",NSLocalizedString(@"ID", nil), merchantList.myloyalty.memberNO];



    if(![ModelClass isBlankString:merchantList.introPic])
    {
          NSLog(@"merchantList.introPic=%@",merchantList.introPic);

        [cell.logoImage setImageUrl:merchantList.introPic];


    }
}
