问题 This question already has an answer here : How can I use a variable from another Controller in JavaFX (1 answer) Closed 6 years ago .

问题 I have searched for this but the answer is too simple to satisfy me :( I want to pass a NSManagedObjectContext from TabBarController to almost every view controllers in my app. In detail, my storyboard structure is kind of like this: TabBarController >>> several tab items views ( this is easy to pass, just pass one time in according view controllers). But I have another relation: TabBarController (the one mentioned above) >>> NavigationController >>> TableViewControllerOne >>>

问题 I want to pass a latitude data and longitude data to another controller called DestinationViewController. DestinationViewController contains a map view, so as user transitions to a new view, they will see a flyover map based on the location(latitude and longitude) data in the first view.
