# HeaderTransitionDelegate
Use for transition table header to navigationBar view while scrolling
## Your class must implement the HeaderViewHandlerProtocol protocol
```swift
public protocol HeaderViewHandlerProtocol: UIViewController {
var largeHeaderView: UIView? { get }
var headerView: UIView? { get }
var tableView: UITableView { get }
}
```
## Usage if your ViewController don't needs extend UITableViewDelegate
```swift
let headerTransitionDelegate = HeaderTransitionDelegate(headerViewHandler: self)
tableView.delegate = headerTransitionDelegate
```
## Usage if your ViewController needs extend UITableViewDelegate
```swift
let headerTransitionDelegate = HeaderTransitionDelegate(headerViewHandler: self)
tableView.delegate = self
.
.
func scrollViewDidScroll(_ scrollView: UIScrollView) {
headerTransitionDelegate?.scrollViewDidScrollHandler(scrollView)
/// Your local work
}
