TableView with multiple prototype cells

Question

I had a simple question regarding a table view with 3 different kinds of prototype cells. The first two occur just once while the third occurs 4 times. Now what I\'m confused ab

Answer 1

Here i wrote code like:

#pragma mark == Tableview Datasource

  - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
  return 2;
 }

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSInteger nRows = 0;
switch (section) {
    case 0:
        nRows = shipData.count;
        break;
    case 1:
        nRows = dataArray1.count;
        break;
    default:
        break;
}
return nRows;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *cellIdentifier = @"cellIdentifier1";
NSString *cellIdentifier1 = @"cellIdentifier2";
SingleShippingDetailsCell *cell;
switch (indexPath.section) {
    case 0:
        cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
        //Load data in this prototype cell
        break;
    case 1:
        cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier1];
        //Load data in this prototype cell
        break;
    default:
        break;
}
return cell;
 }

Answer 2

If you are using three prototype then use three identifiers. Because only one identifier will cause problem. And you will get wrong result. So code like this.

if(indexPath.row==0){
 // Create first cell
}

if(indexPath.row==1){
 // Create second cell
}

else{
 // Create all others
}

You can use switch case also here for best performance.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];

    if (cell.tag == 0) 
   {
    return array1.count;
   }
   else(cell.tag == 1)
   {
    return array2.count;
   }    
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 static NSString *cellIdentifier;

 NSString *membershipType = [membershipTypeArray objectAtIndex:indexPath.row];

 if ([membershipType isEqualToString:@"silver"]||[membershipType isEqualToString:@"gold"])
 {
     cellIdentifier = @"cell";
 }
 else if ([membershipType isEqualToString:@"platinum"])
 {
     cellIdentifier = @"premiumCustomCell";
     cell.customCellImageView.image = [cellImageArray objectAtIndex:indexPath.row];
 }

 cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

 if (!cell) {
     cell = [[CustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
 }
 cell.selectionStyle = UITableViewCellSelectionStyleNone;
 cell.headingLabel.text = [titleArray objectAtIndex:indexPath.row]; 
}
