# UIModalPresentationStyle.pageSheet A presentation style that partially covers the underlying content. ``` case pageSheet ``` ## Discussion In a regular-width, regular-height size class, the system adds a dimming layer over the background content and centers the view controller’s content on top of this layer. The content is roughly the size of a page, where the height is greater than the width. The actual dimensions vary depending on several factors including the device’s screen size and orientation. A part of the background content always remains visible. To provide a custom content size, use the [`UIModalPresentationStyle.formSheet`](/documentation/UIKit/UIModalPresentationStyle/formSheet) style instead, and set 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.
