# UIModalPresentationStyle.formSheet A presentation style that displays the content centered in the screen. ``` case formSheet ``` ## Discussion In a regular-width, regular-height size class, the system adds a layer with a Liquid Glass effect over the background content and centers the view controller’s content on top of this layer. The default content size is smaller than that of the [`UIModalPresentationStyle.pageSheet`](/documentation/UIKit/UIModalPresentationStyle/pageSheet) style. A part of the background content always remains visible. To provide a custom content size, use the modal view controller’s [`preferredContentSize`](/documentation/UIKit/UIViewController/preferredContentSize) property. In a compact-width, regular-height size class, the system displays the view controller as a sheet with part of the background content visible near the top of the screen. In a compact-height size class, the behavior is the same as [`UIModalPresentationStyle.fullScreen`](/documentation/UIKit/UIModalPresentationStyle/fullScreen). Where the background content remains visible, the system doesn’t call the presenting view controller’s [`viewWillDisappear(_:)`](/documentation/UIKit/UIViewController/viewWillDisappear(_:)) and [`viewDidDisappear(_:)`](/documentation/UIKit/UIViewController/viewDidDisappear(_:)) methods. --- Copyright © 2026 Apple Inc.
