# GLKViewDelegate

Drawing callback methods for use with a GLKView object.

## Declaration

```swift
protocol GLKViewDelegate : NSObjectProtocol
```

## Overview

Overview An object that implements the GLKViewDelegate protocol can be set as a GLKView object’s delegate. A delegate allows your application to provide a drawing method to a GLKView object without subclassing the GLKView class.
