TabBar disappear when segue even NavigationController Swift - ios

Well, I'm faced with misunderstanding.
I want my UITabBar to stay displayed when I make a segue from my History button (see picture).
My segue is on Show.
My view is embed in a UINavigationController that is root controller at my UITabBarController.
"Show navigation bar" is turned off on my UINavigationController.
And with all that, I have a grey screen on my segue and no UITabBar...
Thank you in advance!

Try creating a popup view.
In the storyboard remember to set the identifier for the view controller that you are going to. Then delete the segue.
let customAlert = self.storyboard?.instantiateViewController(withIdentifier: "view") as! yourViewController
self.addChild(customAlert)
self.view.addSubview(customAlert.view)
customAlert.view.backgroundColor = UIColor.white

Please make Segue kind as "Show". When select as "Show Detail", the ViewController is present over the Tabbar and hides it.

Tab bar missing when a segue is added

So I have 3 VCs embedded in a navigation controller and a tab bar controller. However, whenever I add a segue from the 3rd VC to the 1st VC, the navigation bar and tab bar disappear from the storyboard. So I tried adding a segue programmatically on the 3rd VC swift file as such:
let collectionVC = self.storyboard?.instantiateViewController(withIdentifier: "collectionVC") as! CollectionViewController
let navigationVC = UINavigationController(rootViewController: collectionVC)
self.present(navigationVC, animated: true, completion: nil)
Unfortunately, with the added code above, the tab bar is still missing but the navigation bar is there. I hope someone could help me.
If I understood correctly your problem, you are using a UINavigationController and you are trying to go from VC3 to VC1, which means that you have a navigation stack like this:
VC1 -> VC2 -> VC3
If you want to go back to VC1, you can use:
navigationController?.popToRootViewControllerAnimated(true)‌​
You will still have your tab bar, your navigation bar and - most important - you won't create another instance of VC1. This is the correct - and easiest - way of dealing with a UINavigationController.

Instantiate View controller with its tab bar from unlinked viewcontroller

I have a viewController related to a Tab Bar Controller: the first one.
Clicking on a cell of its tableview, I'll show programmatically another viewController that's not linked to the first viewController with no segue (because of right reasons).
Now, my goal is to present/instantiate the second viewController related to the tab bar mentioned at the beginning of this question.
If I'll use this:
let vc=storyboard?.instantiateViewController(withIdentifier: "offerteView") as! SecondViewController
It'll be presented the mentioned viewController without the tab bar of course.
How can I solve it?
Embed the first view controller in a navigation controller and use its pushViewController function to show the second view controller.
let vc = storyboard?.instantiateViewController(withIdentifier: "offerteView") as! SecondViewController
navigationController?.pushViewController(vc, animated: true)
when using tab bars the view controllers are called on the basis of their Index and because of this the tab bars are still maintained and this can be done like this.
self.tabBarController!.selectedViewController! = self.tabBarController!.viewControllers[3]
where [3] is the index position of the View Controller.
or
self.tabBarController.selectedIndex = 1;
//Hope it was helpful. Happy Coding.

Swift - SWRevealViewController Left BarButtonItem not working after navigation

I have implemented SWRevealViewController into my project successfully. The side menu is a UITableView with different cells which navigate to differing view controllers. When I tap on the 'profile' cell it defaults to the LoginViewController, there the user will login in and, once verified, will go to the ProfileViewController. This leads to my problem, when I navigate to the ProfileViewController the Navigation bar button (on the left) does not work properly. Likewise, when I press the logout button (the right navigation bar button) it does navigate back to the LoginViewController, however, the menu button does not work.
My navigation functions are as follows:
func switchVC() { //Navigates to the profileViewController
let storyboard = UIStoryboard.init(name: "Login", bundle: nil)
let nav = storyboard.instantiateViewControllerWithIdentifier("Profile")
UIApplication.sharedApplication().keyWindow?.rootViewController = nav
}
func switchBack() { //Navigates back to the LoginViewController
let storyboard = UIStoryboard.init(name: "Login", bundle: nil)
let nav = storyboard.instantiateViewControllerWithIdentifier("Login")
UIApplication.sharedApplication().keyWindow?.rootViewController = nav
}
My storyboard is as follows:
Any help that you may be able to provide would be greatly appreciated. Thank you everyone!
Cheers
Your question is somewhat difficult to answer, but maybe this will help. In order for SWReveal View Controller to work, you always have to route to the main SWReveal Controller Scene for the menu button to work. For example, if my storyboard looked like
SWRevealViewController Scene --> Navigation Controller Scene --> Main View
and I routed back to the Navigation Controller Scene, the button would not work. You have to route back to the first Instance of the SWRevealController Scene that comes before the navigation / any other scenes you are trying to reach.
If you need to add another instance of SWRevealViewController Scene to make that work, just segue through the sw_front identifier to the navigation controller/ view controller you need the button to work in, and then segue it through the sw_rear identifier back to the same one instance of the menu.
Sorry if this answer is confusing, please let me know if I can clarify anything.

Show tab bar on modal View

On click button "Go!" show white View Controller.
I want show tabbar on white ViewController, but it doesn't show. How i make this correctly? Swift please, thanks.
Do this in firstView,so the firstViewController embed in NavigationController,then make a push segue,the tabBar will not dismiss.
You have to use navigation controller to see tab bar. by presenting modally you can't get tab bar in white controller.
Swift code:
let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as SecondViewController
self.navigationController.pushViewController(secondViewController, animated: true)
I think you are using wrong segue just delete old segue and add new segue this way by pressing control key:

Added navigation bar but there is no back button?

I created a table view and from there let say a user pressed a cell it will go to the detailItemView , but the only problem right now is that whenever a user is in detailItemView there is no back button even thought I already embed a navigation Controller
Here's the code that will perform a segue once a user pressed a cell:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using [segue destinationViewController].
var nav = segue.destinationViewController as! UINavigationController
var detailScene = nav.topViewController as! DetailViewController
// Pass the selected object to the destination view controller.
if let indexPath = self.tableView.indexPathForSelectedRow() {
let row = Int(indexPath.row)
detailScene.currentObject = objects?[row] as? PFObject
}
}
The screenshot for the storyboard:
edited Screenshot
I tried to do the answer below but there is still no back button
Another screenshot, the detailView controller doesn't have a back button
Embed the TableViewController inside the NavigationController. Not the DetailViewController directly. Check out the screenshot.
Make sure, that the segue, connecting your TableViewController and your DetailViewController is of type Show (e.g. Push). You have to literally push a new View on top of the Navigationstack.
I've had the same issue just now, resolved by deleting segue, adding again and giving it an identifier straight away.
Click on the StoryBoardSegue, the link between the tableviewcontroller and the detailviewcontroller. In the attributes inspector you may need to click on the "Animates" check even if it is checked. Do this after selecting "Show(e.g.Push)" located in the "Kind" drop down menu. Then run your app and then reselect the same "Animates" option after stopping your app. I think this is a bug and it took my an hour to figure out how to solve this. Additionally, you can use the deprecated "Push" but this will illicit a warning. Deprecated "Push" is under "Kind" in the StoryBoardSegue attributes inspector.
I was struggling with this also, and I named the Identifier of the segue, and now it works. Just select the segue (the arrow) from the Table View to the View , then go to the right top side, where the options are, and select Show the attributes inspector. There is a field for the Identifier.
Just make uinavigation with UItableview then connect the Cell as ( show )
If your current view controller is embedded in a navigation controller, you don't need to embed the detail view controller in a navigation controller. Just connect a button to the detail view controller and the back navigation will come automatically.
change "Interface style" to "Inferred" of detailView in Attributes inspector
