# cancelImageRequest(_:)

Cancels an asynchronous request

## Declaration

```swift
func cancelImageRequest(_ requestID: PHImageRequestID)
```

## Parameters

- `requestID`: The numeric identifier of the request to be canceled.

## Discussion

Discussion When you perform an asynchronous request for image data using the requestImage(for:targetSize:contentMode:options:resultHandler:) method, or for a video object using one of the methods listed in Requesting Video Objects, the image manager returns a numeric identifier for the request. To cancel the request before it completes, provide this identifier when calling the cancelImageRequest(_:) method.
