Struct cacao::view::ViewController

pub struct ViewController<T> {
    pub objc: ShareId<Object>,
    pub view: View<T>,
}

A ViewController is a wrapper around NSViewController in AppKit, and UIViewController in UIKit

This type is interchangeable with a standard View<T>, in that using this simply forwards standard view controller lifecycle methods onto your ViewDelegate. You would use this if you need to be notified of when something is going to be used (e.g, for lifecycle event-based cleanup routines, or something).

Example

use cacao::view::ViewDelegate;

struct ContentViewDelegate;

impl ViewDelegate for ContentViewDelegate {
    const NAME: &'static str = "ContentViewDelegate";

    fn will_appear(&self, animated: bool) {
        println!("This controller is about to appear!");
    }
}

Fields

objc: ShareId<Object>

The underlying Objective-C pointer.

view: View<T>
