UILabel Dynamic Height not working - iphone

Question

im having troubles making my UILabel height dynamic. The label is contained in a custom TableViewCell
I have managed to make the TableViewCellHeight dynamic, but i cant make the label multiple lines.
Whenever i set number of lines = 0 (in IB as well as code), the label/text disappears completely. And lineBreakMode doesnt do much either?
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
Book *eventUp = [appDelegate.eventDataUp objectAtIndex:indexPath.row];
NSString *text = eventUp.date;
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
CGFloat height = MAX(size.height, 44.0f);
return height + (CELL_CONTENT_MARGIN * 2);
//return 66;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [appDelegate.eventDataUp count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"EventUpCVCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
self.eventUpCVCell = nil;
[[NSBundle mainBundle] loadNibNamed:#"EventUpCVCell" owner:self options:nil];
cell = self.eventUpCVCell;
label = [[UILabel alloc] initWithFrame:CGRectZero];
[label setLineBreakMode:UILineBreakModeWordWrap];
[label setMinimumFontSize:FONT_SIZE];
[label setNumberOfLines:0];
[label setFont:[UIFont systemFontOfSize:FONT_SIZE]];
[label setTag:1];
[[cell contentView] addSubview:label];
}
Book *eventUp = [appDelegate.eventDataUp objectAtIndex:indexPath.row];
UILabel *lblMonth = (UILabel *) [cell viewWithTag:kLabel1Tag];
UILabel *lblTitle = (UILabel *) [cell viewWithTag:kLabel2Tag];
UILabel *lblDate = (UILabel *) [cell viewWithTag:kLabel3Tag];
//month.text = eventUp.month;
lblTitle.text = eventUp.title;
lblDate.text = eventUp.date;
//lblDate.lineBreakMode = UILineBreakModeWordWrap;
lblDate.numberOfLines = 1;
lblMonth.text = [NSString stringWithFormat:#"%# ", eventUp.month];
//cell.textLabel.text = eventUp.title;
//cell.detailTextLabel.text = eventUp.date;
//NSLog(#"Hello");
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
// Set up the cell
return cell;
}

You have to set the label frame after creating it, actually you create it with CGRectZero Frame
try:
label = [[UILabel alloc] initWithFrame:CGRectZero];
[label setLineBreakMode:UILineBreakModeWordWrap];
[label setMinimumFontSize:FONT_SIZE];
[label setNumberOfLines:0];
[label setFont:[UIFont systemFontOfSize:FONT_SIZE]];
[label setTag:1];
Book *eventUp = [appDelegate.eventDataUp objectAtIndex:indexPath.row];
NSString *text = eventUp.date;
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
[label setFrame:CGRectMake(0,0,size.width,size.height)];
