WebView not working in u3dxt?

Questions & Answers
1

I can’t get the WebViewTest demo to work. Followed the tutorial to see if I was missing anything but nothing is jumping out at me. I see the GUI buttons, but the web view doesn’t display. Just a default blue background. No errors are thrown. I’m using Unity 4.3.1, Xcode 5.0.2 and U3DXT Pro 1.6.2.1. I have tested on the iPhone 5 and the Simulator.

edit: also tested on iPad 2 with same results. Doesn’t matter if fullscreen is true or false.

EDIT: iOS SDK Pro v1.6.3.0+ resolves this issue. I kept the comment below for historical reasons.

It looks like 4.3.1 changed when/how the Start() function is called. We will develop another solution to adding the WebView automatically when embedding the prefab. In the meantime, try the attached WebViewGameObject.cs. Instead of automatically creating the webview at launch, you have to click on the “Create WebView” button.

using UnityEngine;
using System.Collections;
using U3DXT.iOS.Native.UIKit;
using U3DXT.iOS.Native.Foundation;

public class WebViewGameObject : MonoBehaviour {

	public string homeURL = "http://u3d.as/content/vitapoly-inc/i-os-sdk-native-api-access-from-c-javascript-and-boo/50g";

	// use pixels, automatically converts to DPI
	public Rect locationAndSize = new Rect(10,50,460,260);
		
	// you probabably don't want this unless you want to0 create your own UI with UIKit. Unity will be completely covered.
	private bool fullScreen = false; 
	
	public bool showNavigationButtons = true;
	
	// Use this for initialization
	UIWebView _webview = null;

	void Start () {		
		

	}


	void CreateWebView()
	{
		// figure out parent
		UIView parentView = null;
		if ((UIApplication.deviceRootViewController != null)
		    && (UIApplication.deviceRootViewController.view != null))
			parentView = UIApplication.deviceRootViewController.view;
		else
			parentView = UIApplication.SharedApplication().keyWindow;
		
		
		// create view
		if (_webview == null) {
			if ( fullScreen )
				_webview = new UIWebView(parentView.bounds);
			else
				_webview = new UIWebView(locationAndSize);
			
			this.setURL(homeURL);
		}
		
		
		// add it to parent
		if (_webview.superview == null) {
			parentView.AddSubview(_webview);
		}	
	}
	
	UIWebView getWebView()
	{
		return _webview;	
	}
	
	void OnGUI() {
		if ( !showNavigationButtons )
			return;
		
		GUILayout.BeginArea(new Rect(50, 25, Screen.width - 100, 50));
			GUILayout.BeginHorizontal();
				OnGUICreateWebView();
				OnGUIBack();
				OnGUIForward();
				OnGUIHome();
				OnGUISearch();
				OnHideShow();
			GUILayout.EndHorizontal();
		GUILayout.EndArea();
	
	}

	void OnGUICreateWebView()
	{
