Handoff not working from native app to website

Question

My devices:

• iPad Mini (latest), iOS 8 dp5.
• Macbook Air, Yosemite dp5.

I have Handoff working between the two above devices. Safari, Mail, M

Answer 1

I made two significant changes to my code:

1) configure/destroy and set the NSUserActivity object in viewDidAppear/disappear as opposed to viewDidLoad:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    NSUserActivity *webHandoff = [[NSUserActivity alloc] initWithActivityType:@"com.myApp.iphone.staging.web-browsing"];
    webHandoff.webpageURL = self.handoffWebpageURL;
    [self setUserActivity:webHandoff];
}

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];

    [self.userActivity invalidate];
}

2) Since UIViewController is a subclass of UIResponder and UIResponders have a userActivity property, instead of calling [webHandoff becomeCurrent] I simply called [self setUserActivity:webHandoff];

Not sure why moving it out of viewDidLoad had any impact, and not sure why I need to set it to the viewController's instance of NSUserActivity, but the changes above give me a solid and reliable handoff experience throughout my entire app.
