PTHalfModalPresentationController


@interface PTHalfModalPresentationController : UIPresentationController

A presentation controller that displays its presented view controller anchored at the bottom of the screen. In its default configuration, the presentation controller allows touches outside the presented view controller to be passed through to the view(s) underneath.

The height of the presented view controller is determined by its UIViewController.preferredContentSize instance property. If the preferred content size is not set then the presented view controller will extend to the top of the screen, respecting the safe area insets.

The presented view controller can be dismissed by dragging downwards over its view. Pan gesture recognizers inside the presented view controller are given priority over the drag-to-dismiss gesture.

  • Initializes a PTHalfModalPresentationController instance.
