Installation
----------

### CocoaPods

pod 'PageController'
```

### Carthage

To integrate PageController into your Xcode project using Carthage, specify it in your `Cartfile`:

```
github "hirohisa/PageController" ~> 0.7.1
```

Usage
----------

**viewControllers**

Type is [UIViewController], and element must have title.

```swift

import PageController

class CustomViewController: PageController {

override func viewDidLoad() {
super.viewDidLoad()

viewControllers = createViewControllers()
}

func createViewControllers() -> [UIViewController] {
let names = [
"favorites",
"recents",
"contacts",
"history",
"more",
]

return names.map { name -> UIViewController in
let viewController = ContentViewController()
viewController.title = name
return viewController
}
}
}

```

**MenuBar**

Enable to change backgroundColor, frame.
If you change MenuBarCell.height, then override `frameForMenuBar` and set height.
```swift
/// backgroudColor
menuBar.backgroundColor = UIColor.whiteColor().colorWithAlphaComponent(0.9)
/// skip to auto-select after scrolling
menuBar.isAutoSelectDidEndUserInteractionEnabled = false

/// frame, override this function
override var frameForMenuBar: CGRect {
let frame = super.frameForMenuBar

return CGRect(x: frame.minX, y: frame.minY, width: frame.width, height: 60)
}
```

**MenuBarCell**

Enable to use Custom Cell supported `MenuBarCellable` protocol:
```swift
public protocol MenuBarCellable {
var index: Int { get set }
func setTitle(_ title: String)
func setHighlighted(_ highlighted: Bool)
func prepareForReuse()
}

public func register(_ cellClass: MenuBarCellable) {
guard let cellClass = cellClass as? UIView.Type else { fatalError() }
self.cellClass = cellClass
}

public func register(_ nib: UINib) {
self.nib = nib
}
```

**MenuBarCellable**

```swift
public protocol MenuBarCellable {

// it's used by PageController
var index: Int { get set }

// it is used to set to Label.text, caused by deprecating MenuCell over 0.7
func setTitle(_ title: String)

// it's instead of `updateData` over 0.7,
func setHighlighted(_ highlighted: Bool)

// Called by the menu bar on creating the instance.
func prepareForUse()

}
```
