# resumeOnDidBecomeActive

A Boolean value that indicates whether the view controller automatically resumes the rendering loop when the application becomes active.

```
var resumeOnDidBecomeActive: Bool { get set }
```

## Discussion

The default value is <doc://com.apple.documentation/documentation/Swift/true>. If your application sets this to <doc://com.apple.documentation/documentation/Swift/false>, it must explicitly set the [`isPaused`](/documentation/GLKit/GLKViewController/isPaused) property to <doc://com.apple.documentation/documentation/Swift/false> when the application becomes active.
