Syntax

ModalPresentationStyle
The presentation style for modally presented view controllers.
The presentation style determines how a modally presented view controller is displayed onscreen. In a horizontally compact environment, modal view controllers are always presented full-screen. In a horizontally regular environment, there are several different presentation options.
The default value for this property is Automatic For a list of possible presentation styles, and their compatibility with the available transition styles, see the ISN_UIModalPresentationStyle enum descriptions.
Declaration
public ISN_UIModalPresentationStyle ModalPresentationStyle { get; set; }Property Value

| ISN_UIModalPresentationStyle |
Methods
Dismiss(Boolean, Action)
Dismisses the view controller that was presented modally by the view controller.
The presenting view controller is responsible for dismissing the view controller it presented. If you call this method on the presented view controller itself, UIKit asks the presenting view controller to handle the dismissal.
If you present several view controllers in succession, thus building a stack of presented view controllers, calling this method on a view controller lower in the stack dismisses its immediate child view controller and all view controllers above that child on the stack. When this happens, only the top-most view is dismissed in an animated fashion; any intermediate view controllers are simply removed from the stack. The top-most view is dismissed using its modal transition style, which may differ from the styles used by other view controllers lower in the stack.
Declaration
public void Dismiss(bool animated, Action completion)Parameters
| Type | Name | Description |
|---|---|---|
| System.Boolean | animated | Pass |
| Action | completion | The block to execute after the view controller is dismissed. |
PresentViewController(Boolean, Action)
Presents a view controller modally.
In a horizontally regular environment, the view controller is presented in the style specified by the ModalPresentationStyle property. In a horizontally compact environment, the view controller is presented full screen by default. If you associate an adaptive delegate with the presentation controller associated with the object in viewControllerToPresent, you can modify the presentation style dynamically.
The object on which you call this method may not always be the one that handles the presentation. Each presentation style has different rules governing its behavior. For example, a full-screen presentation must be made by a view controller that itself covers the entire screen. If the current view controller is unable to fulfill a request, it forwards the request up the view controller hierarchy to its nearest parent, which can then handle or forward the request.
Before displaying the view controller, this method resizes the presented view controller's view based on the presentation style. For most presentation styles, the resulting view is then animated onscreen using the transition style in the modalTransitionStyle property of the presented view controller. For custom presentations, the view is animated onscreen using the presented view controller’s transitioning delegate. For current context presentations, the view may be animated onscreen using the current view controller’s transition style.
The completion handler is called after the viewDidAppear: method is called on the presented view controller.
