## Installation

Ready for use on iOS 12+.

### Swift Package Manager

The [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the `swift` compiler. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

Once you have your Swift package set up, adding as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.

```swift
dependencies: [
    .package(url: "https://github.com/ivanvorobei/SPPageController", .upToNextMajor(from: "1.3.0"))
]
```

### CocoaPods:

[CocoaPods](https://cocoapods.org) is a dependency manager. For usage and installation instructions, visit their website. To integrate using CocoaPods, specify it in your `Podfile`:

```ruby
pod 'SPPageController'
```

### Manually

If you prefer not to use any of dependency managers, you can integrate manually. Put `Sources/SPPageController` folder in your Xcode project. Make sure to enable `Copy items if needed` and `Create groups`.

## Usage

`SPPageController` is container controller. Now available 2 system of paging - `.scroll` and `.page`. First using `UICollectionView` like basic view, its good work with content offset but not perfect when device rotated. Second using native `UIPageViewController`. You shoud choose which better for you.

Pass child controllers which using like pages and simple present page controller as you need:

```swift
// Here your controllers
let controllers: [UIViewController] = []
let pageController = SPPageController(childControllers: controllers, system: .page)
present(pageController, animated: true, completion: nil)
```

You can manage layout margins of container. Apple still has bug with it, but my way support it correctly:

```swift
pageController.view.layoutMargins = .init(horizontal: 50, vertical: 0)

// Don't forget enable preserve layout margins for childs:
// childController.view.preservesSuperviewLayoutMargins = true
```

Now for all childs left and right margins will be +50pt.

### Scroll

If you want scroll only programatically, disable scroll between pages by gester:

```swift
pageController.allowScroll = false
```

For scroll by index call this function:

```swift
pageController.safeScrollTo(index: 3, animated: true)
```

### Dismiss

If need disable dismiss by gester (related for modal controllers), set flag to `false`:

```swift
pageController.allowDismissWithGester = false
```
