I would like to know how I can add a back button to my UINavigationBar, I know that If I embed in a Navigation Controller in my main view, that all of this would happen automatically, but that is not what I am trying to do, in fact, the back button could go to any other view I connect the segue to, doesn't even have to be the back.
The back button needs to be the system navigation "back" button, I don't want to have to set image files for my buttons.
I tried dragging in a bar button item in storyboard but nothing shows up, doesn't seem to be doing the trick. The navigation bar was dragged to the view in storyboard (not created programmatically) and it shows up just fine.
I looked at the following similarly asked questions:
-> How do i add a 'back' button to a UINavigationBar manually?
-> How to add a button to UINavigationBar?
-> How to programmatically add a UINavigationBar and a back button on it
but they all point to just embedding the view in a navigation controller, which again, is not what I am trying to do.
If someone can please help me out, provide some sample code I would greatly appreciate it.
Try drag-drop a UIButton object. I have always added manual back button (hardly took the in-built one)

Please refer the image, where I have used the Navigation BarI tried surfing all over, but could not get the solution. Also, I am new to swift, so kindly help! I have a view controller -- Login page, which is connected to an another view controller-- CoreView.swift. I have created 5 subviews in CoreView ViewController. I want to add a Tab Bar where, user can click on the images of the Tab Bar and the corresponding subview should get open. Also, help me to add the images as the subview icon. the icon does not get displayed.
Also, when I try to put the back button from navigation controller, I can set the Title and prompt message, but not the back button in sub views, why so?
Thanks!
Look at this image to see the code and the xib file made
I have the following changes. but still no luck..
Regarding the navigation bar -> you should be able to just drat and drop the UIButton into your left bar button item:
EDIT: updated image to actually show xib implementation.
EDIT2: to link the button use this:
#IBAction func buttonTapped(sender: AnyObject) {
print("Back button tapped")
}
Make sure to connect the button in your interface builder to your custom view. You need to have a custom UIView subclass and should be chosen for your File's owner.
I have an app that has a toolbar, but I don't want the bar at the top, in order to free more viewing space. Therefore I have decided not to use a navigation controller. I'd like to add a back button to the toolbar. How would I go about this?
Adding the button is easy enough, and setting the action to performSegueWithIdentifier is all fine, but what happens is that the previous view just gets loaded again, rather than show it as it was, like a true back button. So if I tap on the 10th row on a tableView and go to a new page, when I press the back button it loads the view from the top again, instead of showing it as where I scrolled down to last.
Even though you don't want a UINavigationBar, you do want a UINavigationController in this case, because it manages the 'back stack' exactly the way you want it. Just hide its navigation bar by setting its navigationBarHidden property to true (in the Storyboard or in the viewDidLoad function of the root view controller).
You can then use navigationController.popViewController(true) as normal, in response to the user clicking your custom back button.
i am making one iOS tabbar application in that i have put 4 different tabs and whenever i click on 1 st tab and load another view after clicking of the first tab. After that when i press back button then tabbar is not displaying .So that i want hint that how can i show that
back the tabbar when we move from one tab from another and yes how i can use consistent the tabbar in whole application can you just guys help me on this i am new to iOS development.
here i am put the screen shot ...
here first screen is this one..
when i tap the video button that are first in the view then another window open
which are as under and see the tabbar is not there...
when in video controller there is tabbar is there but i drag and connect to that then tabbar is disabled
Looking at your screen snapshots, do I correctly assume you're attempting to transition to the "Videos" scene by touching the big "Videos" button in the center of the "Home" scene (rather than touching the tab bar button at the bottom of the screen, which I assume works fine)? If that's the case, you need to have your button tell the view controller's tab bar controller that you want to change the index of the tab bar, and it takes care of it for you. You cannot do the transition using a segue (or at least not without a custom segue, which is even more complicated than the procedure I outline below). If you're changing the view some other way (e.g. using a standard segue or using presentViewController, pushViewController programmatically, etc.), your tab bar can disappear on you.
You later said:
when in video controller there is tabbar is there but i drag and connect to that then tabbar is disabled
Yes, that's true. You cannot use a segue from one of your big buttons to one of the tabs in your tab bar. (Or technically, if you wanted to use a segue, it would be a custom segue which would do something very much like my below code, though perhaps a tad more complicated.) So, rather than using a segue for your big button, you need to write an IBAction (connected to the big Videos button on the Home scene), that tells the tab bar to change its selection:
- (IBAction)clickedVideosButton:(id)sender
{
[self.tabBarController setSelectedIndex:1];
}
A couple of comments:
My answer was predicated on the assumption that your tab bar works as expected when you tap on the buttons of the tab bar, itself. If you tap the buttons at the bottom of the screen, do you transition to your other views correctly and preserve the tab bar? If so, my answer above should solve your issues in getting the big buttons to work. If not, though, then the problem rests elsewhere and you need to show us your code that might account for that (either you're something non-standard in the UITabBarControllerDelegate methods, or your viewDidLoad of the view is doing something nonstandard).
If I understand your user interface design right, you have the tab bar at the bottom as well as the big buttons in the middle, which presumably do the same thing. That is, no offense, a curious user interface design (duplicative buttons, requiring extra tap on a button, etc.). You might want to choose to either use either big buttons (in which you can retire the tab bar, eliminate the IBAction code I've provided above, and just use a nice simple navigation controller and push segues, for example), or just use the tab bar (and lose the home screen, lose the big buttons, etc.).
You also made reference to "press back button", and I don't see any "back" button on any of your screen snapshots. Do I infer that you have a navigation controller and you're doing a pushViewController or push segue somewhere? If you're doing something with back buttons, you might need to clarify your question further.
I'm making an app with multiple views, using a Navigation Controller. I can easily change views by ctrl-dragging from a button to another view, but it doesn't work by doing the same thing, but with a button in the Navigation Bar.
At first, I had a warning about the style of the button, so I changed it from Plain to Bordered. I have no warning now, but when I click on the button, nothing happens.
Thanks for your help!
Try it again but using a UIBarButton, then link the push action to it and it should work.
Right-click the button and drag the circle next to "Push" under Storyboard Segues over to the view you want the button to navigation to.
I have an existing ios5/xcode 4.2 app, and I want a button to open a view that will display a list of items, and have a back button and an add new button.
I thought I could achieve this by adding a button to the main view controller, then dragging in to the storyboard a new UITableViewController, then embed a UINavigationController (editor->Embed In->Navigation Controller).
Then i right clicked on the button, dragged it to the navigation controller, and thought, ok this should work.
However, there is no back button, and xcode will not let me drag one in, nor will it allow me to drag in the button bar item "[+]" for the link to add new.
When I run the app, the list shows, of course I have no way to go back to the view controller with the button on it.
What am i doing wrong? - thanks.
(my question is similar to this
but for xcode 4.2)
Embed the main view controller, not the new one, in a UINavigationController. This should add a simulated UINavigationBar to the main view (if not, set one up under Simulated Metrics). At this point you should be able to drop in a UIBarButtonItem to the main view's simulated bar.
Next, draw a connection from your button to the new UITableViewController to set up a push segue. At runtime, the back button will appear in the bar automatically.
Make sure when you try and drag the items into your view controller that the storyboard is zoomed in. XCode won't let you add items if you are zoomed out.
