UITableView with Various Custom Cells of differing heights within UIView

I am building a IOS app homepage which basically consists of the following structure -

enter image description here

Which is basically a UIView which contains a nested UIScrollView which inturn contains a TableView with 3 Custom Cells.

I pull data out of a dynamic array and filter it into the relevant cell - all works fine other than two issues I cant work out -

1- The custom cells are different heights in the storyboard but when the app is compiled they are always the same height - is it possible to set an auto height on the UITableView Row? If not can anyone explain how I can apply the correct height to each cell?

2- The TableView / View which wraps the table view need to expand to make all dynamic cells visible - how can I achieve this?

below is my tableview method for reference -

-(UITableViewCell *)tableView:(UITableView *)tableView
    cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier =@"CellFeed";
    static NSString *CellIdentifierArtNo =@"CellArtRecNo";
    static NSString *CellIdentifierBook =@"CellBooking";
    UITableViewCell *cell;
    feedData *f = [self.HpFeedArray objectAtIndex:indexPath.section];

    NSString * ArtPString = @"articleP";
    NSString * ArtNoPString = @"article";
    NSString * ArtBook = @"booking";

    if([f.FeedGroup isEqualToString:ArtPString]){
        cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier  
                                               forIndexPath:indexPath];
        CellHp_RecArticleWithImage *cellImage = (CellHp_RecArticleWithImage *)cell;
        cellImage.selectionStyle = UITableViewCellSelectionStyleNone;
        cellImage.artTitle.text = f.FeedTitle;
        cellImage.artImg.text = f.FeedDesc;
        cellImage.artDate.text = f.FeedDate;
        cellImage.textLabel.backgroundColor=[UIColor clearColor];

        return cellImage;
    }
    if([f.FeedGroup isEqualToString:ArtBook]){
        cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierBook 
                                               forIndexPath:indexPath];
        CellHp_BookingAlert *cellBook = (CellHp_BookingAlert *)cell;
        cellBook.selectionStyle = UITableViewCellSelectionStyleNone;
        cellBook.HeadlineLbl.text = f.FeedTitle;
        cellBook.TextBoxLbl.text = f.FeedDesc;
        //cellBook.DateLbl.text = f.FeedDate;

        return cellBook;
    }
    else{
        cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierArtNo 
                                               forIndexPath:indexPath];
        CellHp_RecArticleNoImage *cellNoImage = (CellHp_RecArticleNoImage *)cell;
        cellNoImage.selectionStyle = UITableViewCellSelectionStyleNone;
        cellNoImage.artTitle.text = f.FeedTitle;
        cellNoImage.artImg.text = f.FeedDesc;
        cellNoImage.artDate.text = f.FeedDate;
        cellNoImage.textLabel.backgroundColor=[UIColor clearColor];

        return cellNoImage;
    }

Cheers

It looks like you've got custom UITableViewCell subclasses like CellHp_RecArticleNoImage or CellHp_BookingAlert (may I suggest renaming them to something a little less headache-inducing? ;) ).

In that case, if you only have 3 different cell types, you could do this:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath*)indexPath
{
    UITableViewCell* cell = [tableView cellForAtIndexPath:indexPath];

    if ([cell isKindOfClass:[CellHp_BookingAlert class])
    {
         return 123.0;
    }
    else if ([cell isKindOfClass:[CellHp_RecArticleNoImage class])
    {
         return ...
    }
     ...
}

Or, you could make all your custom classes implement a height method for a cleaner solution and in heightForRowAtIndexPath: you could just get the cell and call its height method.

Re. Question 2, use UIView's sizeToFit method as Tim mentioned.

  1. You can derive static or dynamic (data driven) cell heights from the storyboard by dequeuing them in heightForRowAtIndexPath according to the procedure outlined here: Retrieve custom prototype cell height from storyboard?

  2. I'm not exactly sure I understand this question, but you can get the contentSize of the table view if you're trying to size the table to fit the content.

You need to implement below method to identify the height of cell.

- (CGFloat)tableView:(UITableView *)tableView 
  heightForRowAtIndexPath:(NSIndexPath 
   *)indexPath;
