back view is missing

[james075]

Hi,

I have a first app which performs a navigation to the second app:

- (IBAction)open:(id)sender
{
    NSURL *url = [[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html"];

    [[BFAppLinkNavigation resolveAppLinkInBackground:url] continueWithSuccessBlock:^id(BFTask *task) {
        BFAppLink *link = task.result;

        BFAppLinkNavigation *navigation = [BFAppLinkNavigation navigationWithAppLink:link
                                                                              extras:@{ @"_test_": @"SURPRISE mother fucker!" }
                                                                         appLinkData:@{ @"referer_app_link": @{
                                                                                                @"url": @"applinks://",
                                                                                                @"app_name": @"AppLinks"
                                                                                                }}];
        NSError *error = nil;

        [navigation navigate:&error];

        return task;
    }];
}

The second app shows up but the back view is missing and the app crashes without any output.. did I miss something ?

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    if (self.appLinkReturnToRefererView) {
        self.appLinkReturnToRefererView.hidden = YES;
    }
    AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

    if (delegate.parsedUrl) {

        self.appLink = [delegate.parsedUrl appLinkReferer];

        [self _showRefererBackView];
    }

    delegate.parsedUrl = nil;

}

- (void) _showRefererBackView {
    if (nil == self.appLinkReturnToRefererView) {
        // Set up the back link navigation view
        BFAppLinkReturnToRefererView *backLinkView  = [[BFAppLinkReturnToRefererView alloc] initWithFrame:CGRectMake(0, 30, 320, 40)];
        self.appLinkReturnToRefererView = backLinkView;
    }
    self.appLinkReturnToRefererView.hidden = NO;
    // Initialize the back link view controller
    BFAppLinkReturnToRefererController *alc =[[BFAppLinkReturnToRefererController alloc] init];
    alc.view = self.appLinkReturnToRefererView;
    // Display the back link view

    [alc showViewForRefererAppLink:self.appLink];
}

EDIT:

If I use the solution without using Bolts, everything is fine. I followed this tutorial:

https://developers.facebook.com/docs/ios/share/#linking

It there an issue in the BFAppLinkReturnToRefererView class ?
