# How to set custom cell

## Initialize with cell class

```swift
let videoPager = VideoPagerViewController(cellType: YourCell.self)
```

## Initialize with cell nib

```swift
let cellNib = UINib(nibName: "YourCell", bundle: nil)
let videoPager = VideoPagerViewController(videoPagerCellNib: cellNib)
```

## Initialize with cell nib / class at subclass of `VideoPagerViewController`

```swift
// Make subclass `VideoPagerViewController` and initialize with your cell.

class CustomVideoPager: VideoPagerViewController {

    required init?(coder aDecoder: NSCoder) {
        let cellNib = UINib(nibName: "CustomCell", bundle: nil)
        super.init(coder: aDecoder, videoPagerCellNib: cellNib)
    }
}
```
