# beginSheet(for:modalDelegate:didEnd:contextInfo:certificates:showGroup:)

Displays one or more certificates in a modal sheet.

## Declaration

```swift
func beginSheet(for docWindow: NSWindow!, modalDelegate delegate: Any!, didEnd didEndSelector: Selector!, contextInfo: UnsafeMutableRawPointer!, certificates: [Any]!, showGroup: Bool)
```

## Parameters

- `docWindow`: The parent window to which the sheet is attached.
- `delegate`: The delegate object in which the method specified in the didEndSelector parameter is implemented.
- `didEndSelector`: A selector for a delegate method called when the sheet has been dismissed. Implementation of this delegate method is optional.
- `contextInfo`: A pointer to data that is passed to the delegate method. You can use this data pointer for any purpose you wish.
- `certificates`: The certificates to display. Pass an doc://com.apple.documentation/documentation/Foundation/NSArray containing one or more objects of type doc://com.apple.documentation/documentation/Security/SecCertificate in this parameter. The first certificate in the array must be the leaf certificate. The other certificates (if any) can be included in any order.
- `showGroup`: Specifies whether additional certificates (other than the leaf certificate) are displayed.

## Discussion

Discussion The behavior of this method is somewhat different in macOS 10.4 and later versus OS X v10.3. In OS X v10.3, the sheet displays whatever certificates you pass in the certificates parameter (provided the showGroup parameter is set to true). Starting with OS X v10.4, the sheet displays the leaf certificate (that is, the first certificate in the array you pass) plus any other certificates in the certificate chain that the Security Server can find. If you include all of the certificates in the chain in the certificates parameter, you can ensure that the same certificates are displayed whatever the version of the operating system, and may decrease the time required to find and display the certificates in macOS 10.4 and later. The delegate method has the following signature: - (void)certificateSheetDidEnd:(NSWindow *)sheet         returnCode:(NSInteger)returnCode         contextInfo:(void *)contextInfo The parameters for the delegate method are: The delegate method may dismiss the keychain settings sheet itself; if it does not, the sheet is dismissed on return from the beginSheetForDirectory:... method.
