In your mapped view, use the following code to retrieve the userInfo object.

- (id)initWithNavigatorURL:(NSURL *)URL query:(NSDictionary *)query { 
    if (self = [self initWithNibName:nil bundle:nil]) {
        id myPassedObject = [query objectForKey:@"__userInfo__"];
        // do the rest of your initlization
    }
    return self;
}
