# performAction(_:)

Performs the specified text finding action.

## Declaration

```swift
func performAction(_ op: NSTextFinder.Action)
```

## Parameters

- `op`: The text finding action. See doc://com.apple.appkit/documentation/AppKit/NSTextFinder/Action for the possible values.

## Discussion

Discussion Objects that respond to performTextFinderAction(_:) typically call validateAction(_:) to ensure that the action is valid and then invoke performAction(_:) if validation is successful. When invoking the validateAction(_:) and performAction(_:) the item or sender’s tag should be passed as the parameter. By convention, the sender parameter for this method will have an NSTextFinder.Action set as its tag. The responder that receives this method should pass the tag as the action for this method: - (void)performTextFinderAction:(id)sender {     [self.textFinder performAction:[sender tag]]; }
