WindowEvent::Resized report outer size on iOS

[marysaka]

When starting any applications using winit on iOS, I'm receiving a WindowEvent::Resized coming from layout_subviews corresponding to the full size of the screen instead of the inner size.

I currently workaround this by using Window::inner_size when handling that event.

winit/src/platform_impl/ios/view.rs

Lines 119 to 151 in 44288f6

	extern "C" fn layout_subviews(object: &Object, _: Sel) {
	unsafe {
	let superclass: &'static Class = msg_send![object, superclass];
	let _: () = msg_send![super(object, superclass), layoutSubviews];
	let window: id = msg_send![object, window];
	assert!(!window.is_null());
	let window_bounds: CGRect = msg_send![window, bounds];
	let screen: id = msg_send![window, screen];
	let screen_space: id = msg_send![screen, coordinateSpace];
	let screen_frame: CGRect =
	msg_send![object, convertRect:window_bounds toCoordinateSpace:screen_space];
	let scale_factor: CGFloat = msg_send![screen, scale];
	let size = crate::dpi::LogicalSize {
	width: screen_frame.size.width as f64,
	height: screen_frame.size.height as f64,
	}
	.to_physical(scale_factor as f64);
	// If the app is started in landscape, the view frame and window bounds can be mismatched.
	// The view frame will be in portrait and the window bounds in landscape. So apply the
	// window bounds to the view frame to make it consistent.
	let view_frame: CGRect = msg_send![object, frame];
	if view_frame != window_bounds {
	let _: () = msg_send![object, setFrame: window_bounds];
	}
	app_state::handle_nonuser_event(EventWrapper::StaticEvent(Event::WindowEvent {
	window_id: RootWindowId(window.into()),
	event: WindowEvent::Resized(size),
	}));
	}
	}
