# didChangeArrangementCriteria()

Invoked when any criteria for arranging objects change.

```
func didChangeArrangementCriteria()
```

## Discussion

This method is invoked by the controller itself when any criteria for arranging objects change (sort descriptors or filter predicates) to reset the key paths for automatic rearranging.

### Special Considerations

If you implement a subclass of `NSArrayController` and override [`rearrangeObjects()`](/documentation/AppKit/NSArrayController/rearrangeObjects()) to use additional arrangement criteria, you should invoke this method if those criteria change.

[`func rearrangeObjects()`](/documentation/AppKit/NSArrayController/rearrangeObjects())

Triggers filtering of the receiver’s content.
