Installation

Just add the Source folder to your project or use CocoaPods like this:

pod "PreviewTransition", "~> 2.0.1" swift 3

pod "PreviewTransition", "~> 1.1.5" swift 2

or Carthage users can simply add to their Cartfile:

github "Ramotion/preview-transition"

Usage

1. import PreviewTransition

2. Create UITableViewController inherit, inheriting from PTTableViewController

3. Add UITableViewDelegate methods

public override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return <RowsCount>
}

public override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    return tableView.dequeueReusableCellWithIdentifier(<CellIdentifier>, forIndexPath: indexPath)
}

4. add a ParallaxCell

storyboards: create a cell and inherit from ParallaxCell; don't forget set the identifier <CellIdentifier>

or programmatically: register a cell in viewDidLoad tableView.registerClass(ParallaxCell, forCellReuseIdentifier:<CellIdentifier>)

5. set cell height

6. create image names (image sizes must be equal to screen size or bigger)

let images = [image_name, image_name, image_name, image_name, image_name] // image names

7. set image and text for ParallaxCell

public override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {

    guard let cell = cell as? ParallaxCell else {
      return
    }

    let imageName = images[indexPath.row]

    if let image = UIImage(named: imageName) {
      cell.setImage(image, title: <SetText>)
    }
}

your tableViewController should look like DemoTableViewController

Method public override func tableView(tableView: didSelectRowAtIndexPath indexPath:) we will add later. (step 10)

8. Create UIViewController, inheriting from PTDetailViewController

9. Add action for backButton and call popViewController()

func backButtonHandler() {
    popViewController()
}

10. Push this UIViewController in UITableViewController. Add method

public override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

  // create viewController
  let <YourViewController> = storyboard?.instantiateViewControllerWithIdentifier(<identifier>)
  if case let viewController as <YourViewController> = viewController {
     pushViewController(viewController)
  }
}

11. Configure UINavigationBar

// transparent background
UINavigationBar.appearance().setBackgroundImage(UIImage(), forBarMetrics: .Default)
UINavigationBar.appearance().shadowImage = UIImage()
UINavigationBar.appearance().translucent = true
UINavigationBar.appearance().tintColor = .whiteColor()

// set font
if let font = UIFont(name: <Font name> , size: 18) {
      UINavigationBar.appearance().titleTextAttributes = [
        NSForegroundColorAttributeName : UIColor.whiteColor(),
        NSFontAttributeName : font
      ]
}
