# textShouldEndEditing(_:)

Requests permission to end editing.

```
func textShouldEndEditing(_ textObject: NSText) -> Bool
```

## Parameters

`textObject`

The text object requesting permission to end editing.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the text object should proceed to finish editing and resign first responder status. If the delegate returns <doc://com.apple.documentation/documentation/Swift/false>, the text object selects all of its text and remains the first responder.

## Discussion

The [`NSMatrix`](/documentation/AppKit/NSMatrix) method returns <doc://com.apple.documentation/documentation/Swift/false> if the text field contains invalid contents; otherwise it returns the value passed back from [`control(_:textShouldEndEditing:)`](/documentation/AppKit/NSControlTextEditingDelegate/control(_:textShouldEndEditing:)).

This method is invoked to let the [`NSTextField`](/documentation/AppKit/NSTextField) respond to impending loss of first-responder status. This method’s default behavior checks the text field for validity; providing that the field contents are deemed valid, and providing that the delegate responds, [`control(_:textShouldEndEditing:)`](/documentation/AppKit/NSControlTextEditingDelegate/control(_:textShouldEndEditing:)) is sent to the receiver’s delegate (passing the receiver and `textObject` as parameters).

## See Also

[`delegate`](/documentation/AppKit/NSMatrix/delegate)

The delegate for messages from the field editor.
