Provided Methods

fn showsLargeContentViewer(&self) -> bool

where Self: Sized + Message,

Returns whether the item shows the large content viewer. In general, only views that cannot scale for the full range of Dynamic Type sizes should return YES. For this property to take effect, the item or an ancestor view must have a UILargeContentViewerInteraction.

fn largeContentTitle(&self) -> Option<Retained<NSString>>

where Self: Sized + Message,

Returns a title that should be shown in the large content viewer.

fn largeContentImage(&self) -> Option<Retained<UIImage>>

where Self: Sized + Message,

Available on crate feature UIImage only.

Returns an image that should be shown in the large content viewer.

fn scalesLargeContentImage(&self) -> bool

where Self: Sized + Message,

Returns whether the image should be scaled to a larger size appropriate for the viewer. If not, the image will be shown at its intrinsic size. For best results when scaling, use a PDF asset with its “Preserve Vector Data” checkbox checked.

fn largeContentImageInsets(&self) -> UIEdgeInsets

where Self: Sized + Message,

Available on crate features objc2-core-foundation and UIGeometry only.

Returns insets appropriate for positioning the image in the viewer so that it appears visually centered.
