# runModal(for:modalDelegate:didEnd:contextInfo:)

Runs the receiver modally as a sheet attached to a specified window.

```
func runModal(for window: NSWindow, modalDelegate delegate: Any?, didEnd didEndSelector: Selector?, contextInfo: UnsafeMutableRawPointer?)
```

## Parameters

`window`

The parent window for the sheet.

`delegate`

The delegate for the modal session.

`didEndSelector`

A message sent to the delegate after the user responds but before the sheet is dismissed.

`contextInfo`

Contextual data passed to the delegate in the `didEndSelector` message.

## Discussion

The `didEndSelector` parameter is a selector that takes three arguments. The corresponding method should have a declaration modeled on the following example:

```objc
- (void)identityPickerDidEnd:(CBIdentityPicker *)identityPicker returnCode:(NSInteger)returnCode contextInfo:(void *)contextInfo;
```

where the `identityPicker` argument is the identity picker object, the `returnCode` argument  is the button the user clicked, and `contextInfo` is the same `contextInfo` argument that was passed in the original message.
