I'm using XCode 6.3 to build a TableView of the different Fonts in iOS 8. First, per the book I'm reading, it said that nothing needed to be done regarding the height of the table rows, given that iOS8 takes care of that for you, so once I had everything per the book, the rows should update their heights based on their content, which wasn't the case. Then I tried to play with tableView.rowHeight and I set it equal to UITableViewAutomaticDimension in the TableViewController's viewDidLoad function, and that didn't work either. I also tried changing the height of the rows from Interface Builder, and that didn't seem to have any effect on the heights either. My code is as follows:
class RootViewController: UITableViewController {
private var familyNames: [String]!
private var cellPointSize: CGFloat!
private var favoritesList: FavoritesList!
private let familyCell = "FamilyName"
private let favoritesCell = "Favorites"
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.rowHeight = UITableViewAutomaticDimension
familyNames = sorted(UIFont.familyNames() as! [String])
let preferredTableViewFont = UIFont.preferredFontForTextStyle(UIFontTextStyleHeadline)
cellPointSize = preferredTableViewFont.pointSize
favoritesList = FavoritesList.sharedFavoritesList
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
tableView.reloadData()
}
func fontForDisplay(atIndexPath indexPath: NSIndexPath) -> UIFont? {
if indexPath.section == 0 {
let familyName = familyNames[indexPath.row]
let fontName = UIFont.fontNamesForFamilyName(familyName).first as! String
return UIFont(name: fontName, size: cellPointSize)
} else {
return nil
}
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// Return the number of sections.
return favoritesList.favorites.isEmpty ? 1 : 2
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// Return the number of rows in the section.
return section == 0 ? familyNames.count : 1
}
override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return section == 0 ? "All Font Families" : "Favorite Fonts"
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCellWithIdentifier(familyCell, forIndexPath: indexPath) as! UITableViewCell
cell.textLabel!.font = fontForDisplay(atIndexPath: indexPath)
cell.textLabel!.text = familyNames[indexPath.row]
cell.detailTextLabel!.text = familyNames[indexPath.row]
return cell
} else {
return tableView.dequeueReusableCellWithIdentifier(favoritesCell, forIndexPath: indexPath) as! UITableViewCell
}
}
}
When I run this in the simulator, everything looks right until I scroll all the way to the bottom and I get this:
The attributes of the FontFamily cell are: style = subtitle, and accessory = disclosure indicator.
Any ideas on what I'm be doing wrong?
