# accessoryView The alert’s accessory view. ``` var accessoryView: NSView? { get set } ``` ## Discussion The [`NSAlert`](/documentation/AppKit/NSAlert) class places the accessory view between the informative text or suppression checkbox (if present) and the response buttons. Before you change the location of the accessory view, first call the [`layout()`](/documentation/AppKit/NSAlert/layout()) method. [`alertStyle`](/documentation/AppKit/NSAlert/alertStyle) shows an example of adding an accessory view to an alert. [`buttons`](/documentation/AppKit/NSAlert/buttons) shows the alert generated. Listing 1. Adding an accessory view to an alert ```objc NSTextView *accessory = [[NSTextView alloc] initWithFrame:NSMakeRect(0,0,200,15)]; NSFont *font = [NSFont systemFontOfSize:[NSFont systemFontSize]]; NSDictionary *textAttributes = [NSDictionary dictionaryWithObject:font forKey:NSFontAttributeName]; [accessory insertText:[[NSAttributedString alloc] initWithString:@"Text in accessory view." attributes:textAttributes]]; [accessory setEditable:NO]; [accessory setDrawsBackground:NO]; NSAlert *alert = [[NSAlert alloc] init]; alert.messageText = @"Message text."; [alert setInformativeText:@"Informative text."]; alert.accessoryView = accessory; [alert runModal]; [alert release]; ```  --- Copyright © 2026 Apple Inc.
