SEPageViewWithNavigationBar is a subclass of UIViewController which contains UIPageViewController and changes navigation bar title during the swipe pages, like in Twitter app. Written in Swift, requires iOS 7 or later.

Usage

From code

Just create instance of SEPageViewWithNavigationBar and set view controllers to viewControllers property. Note that SEPageViewWithNavigationBar should be embedded in UINavigationController.

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc1 = storyboard.instantiateViewControllerWithIdentifier("vc1")
let vc2 = storyboard.instantiateViewControllerWithIdentifier("vc2")
let vc3 = storyboard.instantiateViewControllerWithIdentifier("vc3")

let pagedViewController = SEPageViewWithNavigationBar()
pagedViewController.viewControllers = [vc1, vc2, vc3]

self.window?.rootViewController = UINavigationController(rootViewController: pagedViewController)

Using storyboard

1) Drag a UIViewController into storyboard.

2) Place it in the hierarchy that contains UINavigationController.

3) Set custom class to SEPageViewWithNavigationBar in Identity Inspector.

4) Add custom segues in chain between this UIViewController and those that should be pages.

5) Set custom class to SEPageViewSegue and identity to SEPage in Attributes Inspector for each segue.

Configuration

SEPageViewWithNavigationBar allows you to change the following properties:

• titleLabelFont : UIFont

  Font of title label, default is UIFont.systemFontOfSize(16).

• titleLabelTextColor : UIColor

  Color of title label, default is UIColor.whiteColor().

• pageIndicatorTintColor : UIColor

  Tint color of page indicator, default is UIColor(white: 1.0, alpha: 0.4).

• currentPageIndicatorTintColor : UIColor

  Tint color of current page indicator, default is UIColor.whiteColor().

Customization

By default navigation bar title displays current view controller title. Actually, navigation bar title view in SEPageViewWithNavigationBar is UICollectionView, so you can define your own UICollectionViewCell and customize it as you need, using following function:

setCustomTitle(cellClass cellClass: AnyClass, delegateCallback: ((titleCell: UICollectionViewCell, currentPage: Int) -> (UICollectionViewCell)))

For example, if you need image near title label:

class MyCustomCell: UICollectionViewCell
{
    var textLabel : UILabel!
    var imageView : UIImageView!

    override init(frame: CGRect)
    {
        super.init(frame: frame)

        textLabel = UILabel()
        textLabel.translatesAutoresizingMaskIntoConstraints = false
        textLabel.font = UIFont(name: "HelveticaNeue-Light", size: 20)
        textLabel.textColor = UIColor.whiteColor()
        self.contentView.addSubview(textLabel)

        imageView = UIImageView()
        imageView.translatesAutoresizingMaskIntoConstraints = false
        self.contentView.addSubview(imageView)

        let space1 = UIView()
        space1.translatesAutoresizingMaskIntoConstraints = false
        self.contentView.addSubview(space1)

        let space2 = UIView()
        space2.translatesAutoresizingMaskIntoConstraints = false
        self.contentView.addSubview(space2)

        let views = ["textLabel" : textLabel, "imageView" : imageView, "space1" : space1, "space2" : space2]

        self.contentView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|[space1(>=0)][imageView]-4-[textLabel][space2(==space1)]|", options: .DirectionLeftToRight, metrics: nil, views: views))
        self.contentView.addConstraint(NSLayoutConstraint(item: imageView, attribute: .CenterY, relatedBy: .Equal, toItem: self.contentView, attribute: .CenterY, multiplier: 1, constant: 0))
        self.contentView.addConstraint(NSLayoutConstraint(item: textLabel, attribute: .CenterY, relatedBy: .Equal, toItem: self.contentView, attribute: .CenterY, multiplier: 1, constant: 0))
    }

    convenience init()
    {
        self.init(frame:CGRectZero)
    }
}

self.window?.rootViewController = UINavigationController(rootViewController: pagedViewController)

pagedViewController.setCustomTitle(cellClass: MyCustomCell.self) { (titleCell: UICollectionViewCell, pageIndex: Int) -> (UICollectionViewCell) in

    let cell = titleCell as! MyCustomCell

    let titles = ["Explore", "Favorites", "Random"]
    let images = [UIImage(named: "Explore"), UIImage(named: "Favorites"), UIImage(named: "Random")]

    cell.textLabel.text = titles[pageIndex]
    cell.imageView.image = images[pageIndex]

    return cell
}
