Imitate Facebook hide/show expanding/contracting Navigation Bar

由 佐手、 提交于 2019-11-26 05:39:48
In the new iOS7 Facebook iPhone app, when the user scrolls up the navigationBar gradually hides itself to a point where it completely vanishes. Then when the user scrolls down the navigationBar gradually shows itself. How would you implement this behavior yourself? I am aware of the following solution but it disappears right away and it isn't tied to the speed of the user's scroll gesture at all. [navigationController setNavigationBarHidden: YES animated:YES]; I hope this isn't a duplicate as I'm not sure how best to describe the "expanding/contracting" behavior. The solution given by

问题 Context: Let\'s say we have one NavigationController and 2 viewControllers. ViewControllerA has a blue navigationBar, while ViewControllerB has a green one. I set them up like so : override func viewWillAppear(_ animated: Bool) { self.navigationController?.navigationBar.barTintColor = UIColor.blue // Green if ViewController B } It works well when I got from A to B, but when I return, the navigationBar teint is updated after. Like if it was set up in the viewDidAppear . Expected: The

由 那年仲夏 提交于 2019-11-26 04:30:01
问题 How do I make a UISegmentedControl as a part of an UINavigationBar below it? Is it connected to the UINavigationBar or is it a complete separate view just added as a subview to the UINavigationController \'s view controller. Looks like it is part of the UINavigationBar since there is a shadow below the bar. 回答1: It's a simple effect to accomplish. First, place a segment in a toolbar. Place this toolbar right below the navigation bar. Set the delegate of the toolbar to your view controller,
