# init(target:action:)

Initializes the gesture recognizer with the specified target and action information.

```
init(target: Any?, action: Selector?)
```

## Parameters

`target`

The object whose action method is called when the gesture is recognized. You must not specify `nil` for this parameter.

`action`

A selector that identifies the method to call when the gesture is recognized. This method must be implemented by the object in `target`. You must not specify `nil` for this parameter.

## Return Value

The initialized gesture recognizer object or `nil` if an error occurred.

## Discussion

This method is the designated initializer. Subclasses must call this method from their own custom initialization methods. Call the method before performing other tasks.

This method records the specified `target` and `action` values and prepares the gesture recognizer for use.

The `action` method must have one of the following signatures:

```objc
- (void)handleGesture;
- (void)handleGesture:(NSGestureRecognizer *)gestureRecognizer;
```
