GLKViewDelegate Protocol Reference

| Framework | /System/Library/Frameworks/GLKit.framework |
| Availability | Available in iOS 5.0 and later. |
| Declared in | GLKView.h |
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.
Instance Methods
glkView:drawInRect:
Draws the view’s contents. (required)
Parameters
- view
The view requesting that its contents be redrawn.
- rect
A rectangle that describes the area that needs to be updated.
Discussion
The semantics of this method are identical to those of the drawRect: method; the GLKView object makes its OpenGL ES context the current context and binds its framebuffer as the target for OpenGL ES rendering commands. Your delegate method should then draw the view’s contents.
Availability
- Available in iOS 5.0 and later.
