systemLayoutSizeFittingSize does not work on a external Xib cell - ios

Question

I have been struggling for 2 days with this problem.
I have a UIViewController with a UITableView on the storyboard.
But I want to reuse the design for a custom cell so I use an Xib file to design the cell.
The cells contains a label that gets the content at runtime so the height of it varies.
I am using autolayout I have all the constraints and set lines of my label as 0;
-(void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.tableView.dataSource = self;
self.tableView.delegate = self;
[self.tableView registerNib:[UINib nibWithNibName:#"PostingTableViewCell" bundle: [NSBundle mainBundle]] forCellReuseIdentifier:#"PostingCell"];
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"PostingCell";
self.customCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (self.customCell == nil)
{
self.customCell = [[PostingTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
NSDictionary *post = [self.posts objectAtIndex:indexPath.section];
NSString *contentString = [post objectForKey:#"content"];
self.customCell.contentLabel.text = contentString;
self.customCell.bounds = CGRectMake(0.0f, 0.0f, CGRectGetWidth(tableView.bounds), CGRectGetHeight(self.customCell.bounds));
[self.customCell setNeedsLayout];
[self.customCell layoutIfNeeded];
CGFloat height = [self.customCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize].height;
return height;
}
My code works when I put my custom cell on my tableViewController in the storyboard, but when I migrate it to the xib file, the height of the tableviewcell no longer adjusts.
here is a screen shot of my xib file and constraints
Here is my cellForRowAtIndexPath method:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"PostingCell";
PostingTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSDictionary *post = [self.posts objectAtIndex:indexPath.section];
NSString *contentString = [post objectForKey:#"content"];
cell.contentLabel.text = contentString;
}

When I hard code the height to 150 screenshot below:

I'm still not sure why you're doing any of this in heightForRowAtIndexPath
static NSString *CellIdentifier = #"PostingCell";
self.customCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (self.customCell == nil)
{
self.customCell = [[PostingTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Try this
1. Adjust the height of the cell in xib.
2. Try something like this
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return self.customCell.bounds.size.height;
}
