I am using this code to show the VC when someone clicks on the preference pane.
let popover = NSPopover()
popover.contentViewController = NSStoryboard(name: "Main", bundle: nil).instantiateControllerWithIdentifier("AuthVC") as? NSViewController
popover.animates = true
popover.behavior = NSPopoverBehavior.Transient
When the view shows up, the top bar is a standard bar. I want it to be like this with an arrow:
When I use this code: popover.showRelativeToRect(CGRectNull, ofView: ViewController , preferredEdge: NSRectEdge) In ofView It wants an NSView However mine is a ViewController.
You have to use -showRelativeToRect:ofView:preferredEdge: and pass an empty rect and the view in the menu to get the anchor (arrow).

I want to be able to create a TabBarViewController with some tabs and then push into the given tabs
let tabBarViewController = UITabBarController()
let redVc = UIViewController()
redVc.view.backgroundColor = .red
let blueVc = UIViewController()
blueVc.view.backgroundColor = .blue
tabBarViewController.viewControllers = [redVc, blueVc]
This created a tabBarViewController with a red and a blue tab. Now I want to push a yellow VC to the red tab so that I have a yellow and a blue tab.
let yellowVc = UIViewController()
yellowVc.view.backgroundColor = .yellow
tabBarViewController.modalPresentationStyle = .fullScreen
// this doesn't work
viewController.present(tabBarViewController, animated: true)
// must use this
tabBarViewController.viewControllers![0] = yellowVc
What should I do to be able to present in a given tab?
You can setup your UITabbarController in such a way, that each of it's child is a UINavigationController.
All together, you then have the following hierarchy:
UITabbarController
child1 (UINavigationController)
first content ViewController
child2 (UINavigationController)
second content ViewController
Now from within each contentViewController, you can use navigationcontroller.push to push a new viewController to the stack and it will stay inside the tabbar.
I'm trying to show a storyboard as a sheet right after the window has loaded.
override func windowDidLoad() {
super.windowDidLoad()
let storyboard = NSStoryboard(name: NSStoryboard.Name(rawValue: "Init"), bundle: nil)
let controller = storyboard.instantiateInitialController() as! NSViewController
self.window!.contentViewController?.presentViewControllerAsSheet(controller)
}
Unfortunately, the sheet is shown out of position and behind the window.
When I run the same code inside a button, everything works fine.

How do i correctly show a storyboard sheet after loading a window?
I have more knowledge of the iOS ecosystem but I suppose that you should show new windows only after the origin window has been shown. windowDidLoad is called when the view has been loaded, not when it has been shown.
Therefore, you should probably put your code into viewDidAppear of the contentViewController.
I'm currently trying to build a menubar app. Therefore I need a NSWindowController for an login field. It must be possible to open this NSWindowController when pressing a menu item and also close that window when the user clicked on cancel.
I used showWindow(self) and NSApp.hide(self) but this didn’t work for me. So has anyone an idea what I can try?
Assuming you are using Storyboard
Add an NSWindowController to the storyboard and uncheck visible at launch of the window.
In AppDelegate create a property windowController
var windowController : NSWindowController!
In AppDelegate create an IBAction.
In the action get the main storyboard with
let mainStoryBoard = NSStoryboard(name: NSStoryboard.Name(rawValue: "Main"), bundle: nil)
Then instantiate and assign the window controller (the identifier must match the storyboard identifier)
windowController = mainStoryBoard.instantiateController(withIdentifier: NSStoryboard.SceneIdentifier(rawValue: "Login")) as! NSWindowController
Get the associated view controller (LoginController is the custom class of the view controller)
let loginController = windowController.window!.contentViewController as! LoginController
Show the main window
windowController.showWindow(self)
In Interface Builder connect the NSMenuItem to First Responder (red cube) and then to the created IBAction.
You can close the window either with the red close button or you need to add custom logic.
If you use a XIB create an NSWindowController subclass and load the XIB with windowController = MyWindowController(window: nil), activate your app with NSApp.activate(ignoringOtherApps: true) get the associated window with let controllerWindow = windowController.window! and show the window with controllerWindow.makeKeyAndOrderFront(self)
I'm implementing a drawer layout design in an app.
But my app starts with a small screen with an animated logo (simple HTML5 animation), then a login screen (g+ and Facebook), then the main screen where I'm implementing the MMDrawerController.
The question is in my AppDelegate:
window?.rootViewController = centerContainer
window?.makeKeyAndVisible()
So the app start in this screen. Is it possible to not make rootviewcontroller the center container and still using MMDrawerController?
I need to add MMDrawerController to my third viewcontroller in my app
But, in order to MMDrawerController to work, it requires to be the rootViewController
I allready tried to add to my first ViewController an Empty MMDrawerLayout but, then, the third controller no longer works
//global var
var centerContainer : MMDrawerController?
// then the appdelegate
let rootViewController = self.window!.rootViewController
let mainStoryBoard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let centerViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("GaleriaPeliculas")
let leftViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("LeftSideViewController")
let leftSideNav = UINavigationController(rootViewController: leftViewController)
let centerSideNav = UINavigationController(rootViewController: centerViewController)
//And here is the problem,
window?.rootViewController = centerContainer //how can it work without this line??
window?.makeKeyAndVisible()
Is it possible to not make rootviewcontroller the center container and still using MMDrawerController?
No. You need to keep MMDrawerController as the rootViewController if you still want to make use of the left/right drawers. It's no different than a UITabBarController in the sense that it contains multiple view controllers to be conditionally displayed.
I simply want to present a small option dialog over an existing main UIViewController/UIView , so that on an IPad I would see a small Dialog and in the Background I will see the Main View.
I managed to show a UIViewController/UIView in a modal view style as follow:
func showoptions(){
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewControllerWithIdentifier("Options") as! UIViewController
controller.modalPresentationStyle = UIModalPresentationStyle.Popover
let popoverPresentationController = controller.popoverPresentationController
// result is an optional (but should not be nil if modalPresentationStyle is popover)
if let _popoverPresentationController = popoverPresentationController {
// set the view from which to pop up
_popoverPresentationController.sourceView = self.view;
//_popoverPresentationController.sourceRect = CGRectMake(60, 100, 500, 500)
//_popoverPresentationController. .setPopoverContentSize(CGSizeMake(550, 600), animated: true)
//_popoverPresentationController.sourceView.sizeToFit();
// present (id iPhone it is a modal automatic full screen)
self.presentViewController(controller, animated: true, completion: nil)
}
}
But I have still some issues:
1. Howto get rid of the arrow shown at the border.
2. Howto size this modal view. It is shown to small and I would like to fit it to the largest controls in the UIControllerView/UIView.
any help ?
Try changing _popoverPresentationController.permittedArrowDirections to empty option set
Change controller.preferredContentSize to match your desired size
I needed something similar and ended up presenting a view controller as a modal with a transparent background over the current context. There I made a smaller opaque UIView with what I wanted.
