I am facing a problem I cannot solve alone. At least, I don't know what's the right way to program this. I am writing an app which will open a PopupView as a Subview of my main menu when pressing + . This looks like this:
As soon as this subview is visible, I want to perform different segues (when pressing button 1,2,3 or 4) so this popup can change the view to 1-4:
I created a separate Storyboard for this popup and when pressing +, the initial view of it will be added as a subview:
let addFilePopup : UIStoryboard = UIStoryboard(name: "AddFilePopup", bundle: nil)
animations.showInView(self.view, aView: addFilePopup.instantiateInitialViewController()?.view, animated: true)
// the method for adding the PopupView as a Subview
func showInView(superView: UIView, aView: UIView!, animated: Bool)
{
aView.center = superView.center
superView.addSubview(aView)
if animated
{
self.showAnimate(aView)
}
}
Showing the Popup itself works so far, but as soon as I press one button, the segue of the Popup is not performed... Do you have any hints to me for this problem? Besides, is this the right approach?
If you also could let me know how I can make the superview.alpha = 0,5 and ignoring touches without taking affect on the subview that would be great too. Thanks in advance!

So in my attached image I show my subclass I'm creating for my HOME button. I have many VCs with a HOME button and I want to connect them to this class to make them all send the user HOME
So far, I made my button to take this class, as shown in the image. My issue is I'm not able to connect my IBAction here and not sure why.... would appreciate any tips anyone can tell me about why I'm not able to connect my IBAction function to the button right now....
Another confusing thing is that although I haven't given any of the other buttons in this stackview of buttons a class, I'm actually able to connect any of my other buttons in this stackview to my IBAction... which I find odd.
class HomeButton: UIButton {
#IBAction func showHomeVC(sender: AnyObject) {
var sb: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
var vc: UINavigationController = sb.instantiateViewController(withIdentifier: "HomeNC-ID") as! UINavigationController
self.present(vc, animated: false, completion: nil)
}
}
I'm aware that I can simply go to each VC where there's a HOME button and create an IBAction from each and just paste this code in there and it will work, but I would like to do this another way where I don't have to have so much of the same code being repeated.... I would like to know what changes need to be made to make this happen.
The error that you are are getting is because you are using the class of UIButton which doesn't have the property to display a view controller. You should present it either on a UIViewController, or one of the other types.
It is linked up but you just can't present a view controller using self (UIButton)
I am learning iOS with few sample projects. I have two view controllers in that first VC has few buttons and a mapview and the second VC has tableview showing a set of results. I have embed the both viewcontrollers in navigationViewController.By clicking a button from First VC i am able to show the tableview (using show segue) and able to go back to first VC through navigation. Now my query is I want to display the tableview (second VC) in place of one view object (map view) defined in firstVC rather than padding the tableview entirely in full screen. My problem is when showing another Viewcontroller i still want to see the few viewobjects from firstVC so I am trying to display the secondVC on top of mapview when i click on a button which triggers the segue.I have to use the single interface, so I need to load the tablview results from SecondVC into firstVC by replacing mapView's view with tableview.Please let me know your ideas if it is possible and any other ideas to achieve the same are most welcomed.
Sreekanth Gundlapalli,
All you need to do is to add the TableView controller's view as subview to your view Controller. In order to simplify the process I personally prefer using the ContainerView,
Step 1 : Add a ContainerView to your View Controller and add the auto layout constraints to it, because your tableView will be loaded inside this container view you donate have to apply any auto layout constraint to your tableView to keep it in place :)
ex :
Step 2 : Drag an IBOutlet to the container view.lets call it as containerView :)
Step 3 : Now its up to you to have two view controller 1 for loading map and 1 for loading tableView, or you will have map view as your view controller subview and you will either hide it or remove it and add container view but I personally prefer having code clean n neat so I prefer having two different VCs
so lets create 2 VCs lets call them as viewController1 & viewController2 Savy ??
Step 4 :
lets write a method which actually loads VC and adds its view as subview to your ViewController
func changeEmbededVC(for status : Int) {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
if status == 0 {
mehereButton.tag = 1
let vc = storyboard.instantiateViewController(withIdentifier: "viewController1")
vc.willMove(toParentViewController: self)
containerView.addSubview(vc.view)
self.addChildViewController(vc)
vc.didMove(toParentViewController: self)
}
else {
mehereButton.tag = 0
let vc = storyboard.instantiateViewController(withIdentifier: "viewController2")
vc.willMove(toParentViewController: self)
containerView.addSubview(vc.view)
self.addChildViewController(vc)
vc.didMove(toParentViewController: self)
}
}
I believe code is pretty self explanatory :D now what is mehereButton.tag = 1 ?? Simple you want to toggle view on button press don't you :D hence I have created a IBOutlet for mehereButton and changing its tag :)
now finally in IBAction of mehereButton
#IBAction func buttonTapped(_ sender: UIButton) {
self.changeEmbededVC(for: self.mehereButton.tag)
}
but we need to load one of the view by default isn't it :D
so change your viewDidAppear to
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
self.changeEmbededVC(for: 0)
}
Hope I answered your question In detail :P I know you can't neither up vote or accept answer as you don't have enough reputation :) but hope it will help somebody in future as well :)
I have just made a small transition so my project loads a different storyboard as its main (did it in the info.plist).
I have my new storyboard to keep my viewController that are responsible for login screen etc. Just to make it more clear.
After the login button is tapped I want to initiate a navigationController from another storyboard:
func instantiateViewController(fromStoryboard storyboard: String, withIdentifier identifier: String) -> UIViewController! {
let storyboard = UIStoryboard(name: storyboard, bundle: nil)
let viewController = storyboard.instantiateViewControllerWithIdentifier(identifier)
return viewController
}
#IBAction func loginButtonTapped(sender: UIButton) {
let viewController = instantiateViewController(fromStoryboard: "Main", withIdentifier: "MainNavigationController")
presentViewController(viewController, animated: true, completion: nil)
}
Everything works correctly but one thing is driving me nuts.
After presenting the MainNavigationController from Main.storyboard its view hierarchy is not maintained.
What I mean is, the labels and buttons which supposed to be on top of another, full screen UIView (but are not its child and so they should remain) are now behind it.
What might be causing this and what is the simplest way to make them appear on top (as they do whey I open main.storyboard)
EDIT
I added a line of code in the rootView of the MainNavigationController in its viewDidLoad method:
self.view.sendSubviewToBack(wholeScreenView)
and it solved the problem.
However, does anybody know why do I have to code it myself and the views are not like in the Main.storyboard?
The storyboard is not configured the way you think it is. Your wholeScreenView is in fact in front of the other views, in the storyboard. The other views (the labels and buttons) are not subviews of wholeScreenView; they are subviews of the main view, and so is wholeScreenView. It is a later subview, so it is in front of them.
I'm trying to do a instagram-like (or any app with a toolbar in fact) toolbar, to navigate from screens to screens.
I have a navigation controller, with 5 screens, and I already did this :
In each screen, in the viewDidLoad, I put:
self.toolbarItems = self.navigationController!.toolbarItems
And in the navigationController, for one BartbuttonItem I have this
function for example:
#IBAction func profileButtonClicked(sender: UIBarButtonItem) {
self.popToRootViewControllerAnimated(false)
self.performSegueWithIdentifier("showProfile", sender: self)
}
So it is working, but I don't like the transition when I go first to the navigationController then to the newViewController, I would like there is no transition at all.
I would be thankful if you help me.

Click the view Controller on main storyboard
Then go to attribute inspector
There is a option called transition style, choose cross dissolve
OR Use
self.sourceViewController.presentViewController(self.destinationViewController as! UIViewController, animated: false, completion: nil)
FOUND :
just needed to uncheck "Animates", when you click on the segue in the storyBoard and then go to Attributes Inspector and just uncheck this checkbox.
I was wondering if i could make some sort of a segue between these 2 views in a Xib file.
the main View is loaded into a scrollview in the storyboard.
.
(so if ik click Bewerken(edit) i would get pushed to the view controller on the right)
Thanks!
I would suggest changing this to a Container View inside the storyboard instead of a separated Xib. You can add and position/size UIContainerView as a subview and add a"Storyboard Embed Segue to attach another ViewController. This is what it will look like in IB/Storyboard:
During runtime, the blue UIView (or the embedded UIViewController if you like) will be embedded in the hosting UIView as a subview:
If you change your implementation to this, you are in the beautiful segue world where you can just drag-and-drop segues :)
You could do 2 things:
1 - Wrap the main view in a Navigation Controller so you can do the following:
#IBAction func loadEditController(sender:UIButton){
let editController = RegisterController(nibName:"RegisterXIB", bundle:nil)
navigationController?.pushViewController(editController, animated: true)
}
2 - Present the Edit Controller over the current context and animate it yourself
#IBAction func loadEditController(sender:UIButton){
let editController = RegisterController(nibName:"RegisterXIB", bundle:nil)
editController.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext
presentViewController(editController, animated: false, completion: nil)
//Move it offscreen and the animate it here
}
