This is a control for iOS written in Swift. DTPagerController is simple to use and easy to customize.

## Usage

DTPagerController is extremely easy to use. In order to display two view controllers inside a pager controller. All you have to do is this many lines of code.

```swift
let viewController1 = ViewController()
let viewController2 = ViewController()
let pagerController = DTPagerController(viewControllers: [viewController1, viewController2])
```
### Update page index
There are 3 different ways to update selected page index programmatically.

```swift

// Update selected page index with animation
pagerController.selectedPageIndex = 1

// Update selected page index with animation
pagerController.setSelectedPageIndex(1, animated: true)

// Update selected page index without animation
pagerController.setSelectedPageIndex(1, animated: false)

```

### Custom UI
DTPagerController is also customizable in case you want to implement your own UI.

```swift

// Change the height of segmented control
pagerController.preferredSegmentedControlHeight = 60

// Change normal font of each segmented control
pagerController.font = UIFont.customFont(ofSize: 15)

// Change selected font of each segmented control
pagerController.selectedFont = UIFont.boldCustomFont(ofSize: 15)

// Change normal text color of each segmented control
pagerController.textColor = UIColor.black

// Change selected text color of each segmented control
pagerController.selectedTextColor = UIColor.red

// Change scroll indicator height
pagerController.perferredScrollIndicatorHeight = 3

```

### Custom segmented control
From version **2.0.0**, DTPagerController supports custom segmented control. Therefore, instead of using default **DTSegmentedControl**, you can provide your own segmented control or any 3rd-party segmented control libraries available out there. All you have to do is making your custom UIControl conform **DTSegmentedControlProtocol**. For example, as shown in sample project, **HMSegmentedControl** is made to conform **DTSegmentedControlProtocol** by using extension:

```swift

extension HMSegmentedControl: DTSegmentedControlProtocol {

public func setImage(_ image: UIImage?, forSegmentAt segment: Int) {
// Custom page control does not support
}

public func setTitle(_ title: String?, forSegmentAt segment: Int) {
// Custom page control does not support
}

public func setTitleTextAttributes(_ attributes: [AnyHashable : Any]?, for state: UIControlState) {
if state == UIControlState.normal {
titleTextAttributes = attributes
}
else if state == UIControlState.selected {
selectedTitleTextAttributes = attributes
}
}

}

```

Then we create new pager controller with the custom segmented control:

```swift

init(viewControllers controllers: [UIViewController]) {
let segmentedControl = HMSegmentedControl(sectionTitles: ["Page 1", "Page 2", "Page 3"])
super.init(viewControllers: controllers, pageSegmentedControl: segmentedControl!)
}

```

When using custom segmented control, it is recommneded to override/take a look at the following methods to customize behavior and appearance of each segments:

```swift

// Setup custom segmented control
func setUpSegmentedControl(viewControllers: [UIViewController])

// Update a custom appearance for segment
func updateAppearanceForSegmentedItem(at index: Int)

// Update a custom scroll indicator if exists
func updateScrollIndicator(with offsetRatio: CGFloat, scrollView: UIScrollView)

// Setup custom scroll indicator
func setUpScrollIndicator()

// Manually update segment title
func setTitle(_ title: String?, forSegmentAt segment: Int)

// Manually update segment image
func setImage(_ image: UIImage?, forSegmentAt segment: Int)

```
