Dequeuing Cells

UITableView

// Before
let cell = tableView.dequeueReusableCell(withIdentifier: "TitleCell", for: indexPath) as! TitleCell

// After
let cell = tableView.dequeue(TitleCell.self, for: indexPath)

UICollectionView

// Before
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionViewCell", for: indexPath) as! CollectionViewCell

// After
let cell = collectionView.dequeue(CollectionViewCell.self, for: indexPath)

Registering Cells

Simple protocol extensions to simplify registering a cell in UITableViewController and UICollectionViewController.

Before:

self.tableView.registerClass(ItemCell.self, forCellReuseIdentifier: "ItemCell")

After:

self.tableView.register(ItemCell.self)

Also, accessing the cell identifier is as easy as using ItemCell.reuseIdentifier.

UIAlertController

Dismissable alert

let alertController = UIAlertController.dismissableAlert(title: "Not allowed access", message: "Please contact your admin to get access.")
self.presentViewController(alertController, animated: true, completion: nil)

Destructive confirmation alert

let alertController = UIAlertController.destructiveConfirmationAlert(message: "Are you sure you want to log out?", destructiveActionTitle: "Log out") {
    self.controllerDelegate?.settingsControllerDidPressLogoutButton(self)
}
self.presentViewController(alertController, animated: true, completion: nil)

Error alert

let alertController = UIAlertController.errorAlert(error)
self.presentViewController(alertController, animated: true, completion: nil)

Progress alert

let progressAlert = UIAlertController.progressAlert("Creating album...")
self.presentViewController(progressAlert, animated: true, completion: nil)
self.fetcher.createAlbum(title: self.titleTextField.text, photos: self.selectedPhotos) { error in
    progressAlert.dismissViewControllerAnimated(true) {
        if let error = error {
            let alertController = UIAlertController.errorAlert(error)
            self.presentViewController(alertController, animated: true, completion: nil)
        } else {
            // Success
        }
    }
}

UILabel

Calculate width

let width = self.usernameLabel.width()
// Do something with new width

UIView

Shake

self.fetcher.authenticate(username, password: password) { clientID, clientSecret, accessToken, refreshToken, expiresIn, error in
    if let error = error {
        // Update UI to display error
        self.tableView.shake()
    } else {
      // success
    }
}

UIImage

Centered frame

let image = UIImage(named: "art.png")!
let frame = image.centeredFrame()
// Do something with new frame

Image with colour

let image = UIImage(color: .red)
button.setBackgroundImage(image, for: .normal)

or, if you need the image to have specific dimensions

let image = UIImage(color: .red, size: someSize)

UIViewController

Application window

let window = self.applicationWindow()
