Tableview cells not resizing properly to content - ios

Question

For some strange reason the TableView Cells are not fitting the dynamic textual content properly. They should have a slight margin between the top and bottom of cell. Unfortunately, depending on the amount of textual content, some cells have no top and bottom margin(tightly packed) and others have huge margins.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
float result = 30;
if (indexPath.section != 0){
CGSize size = [[self textForIndexPath:indexPath isTitle:NO] sizeWithFont:kITDescriptionFont constrainedToSize:CGSizeMake(220, CGFLOAT_MAX) lineBreakMode:UILineBreakModeWordWrap];
result = MAX(result, size.height);
}
return result;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *doubleCellIdentifier = #"ITDoubleDetailCEllIdentifier";
static NSString *cellIdentifier = #"ITDetailCEllIdentifier";
NSString *cellIdent = (indexPath.section == 0)? doubleCellIdentifier : cellIdentifier;
ITDescriptionCell *cell = (ITDescriptionCell *)[tableView dequeueReusableCellWithIdentifier:cellIdent];
if (!cell) {
UITableViewCellStyle style = (indexPath.section == 0)? UITableViewCellStyleValue2 : UITableViewCellStyleDefault;
cell = [[ITDescriptionCell alloc] initWithStyle:style reuseIdentifier:cellIdent];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell.textLabel setNumberOfLines:0];
[cell.textLabel setFont:kITDescriptionFont];
}
else {
[cell.textLabel setText:#""];
[cell.detailTextLabel setText:#""];
}
[cell sizeToFit];
return cell;
}

Answer 1

You need to dynamically calculate the height of your text and based on that and the padding you want, adjust the height of the cell through the following delegate method:
#define PADDING 10.0f
- (CGFloat)tableView:(UITableView *)t heightForRowAtIndexPath:(NSIndexPath *)indexPath {
Subscription *sub = [_dictTask valueForKeyPath:#"subscription"];
NSArray *meta = sub.meta.allObjects;
NSString *text = [[meta objectAtIndex:indexPath.row] valueForKey:#"sum_value"];
CGSize textSize = [text sizeWithFont:[UIFont systemFontOfSize:14.0f] constrainedToSize:CGSizeMake(self.tableView.frame.size.width - PADDING * 3, 1000.0f)];
return textSize.height + PADDING * 3;
}
