[SOLVED] Dynamically Adjust Width of Table View Embedded in Popover to Fit Cell Content

Dynamically Adjust Width of Table View Embedded in Popover to Fit Cell Content

My landscape, iPad app has a table view controller presented as popover from a bar button item.

To fit the popover to the table view size, I do this on the table view controller's code:

override func viewDidLoad()
{
    super.viewDidLoad()

    tableView.estimatedRowHeight = 44.0
    tableView.rowHeight = UITableViewAutomaticDimension
    tableView.scrollEnabled = false
}

override func viewWillAppear(animated: Bool)
{
    super.viewWillAppear(animated)

    tableView.reloadData()   
    preferredContentSize = tableView.contentSize
}

This works fine for adjusting the popover's height to that of the table view (taking into account number of rows and height of each row).

However, if I set the label of one of the cells to a string that is too long, it will truncate (...), even though there is plenty of room on screen for the popover (and the table view) to grow further horizontally.

I could hard-code some big-enough width, like this:

override func viewWillAppear(animated: Bool)
{
    super.viewWillAppear(animated)

    tableView.reloadData() 

    var size = tableView.contentSize
    size.width = 600  
    preferredContentSize = size 
}

...but I would prefer a more dynamic and elegant solution (e.g. minimum width that fits all cells' contents).

Solution

Use these for handle them dynamically

DynamicView.autoresizingMask = UIViewAutoresizing.FlexibleTopMargin .union(UIViewAutoresizing.FlexibleLeftMargin .union(UIViewAutoresizing.FlexibleRightMargin))
