iOS Storyboard flip horizontal animation disables text fields - ios

I have a very simple story board . There is no code involved in this yet. The problem I am having is that when I change the transition to "Flip Horizontal" the text fields get disabled for some reason (i.e. clicking on the text field does not bring up the keyboard). This is triggered when with the following sequence: click on text field keyboard pops up -> hit next -> click on text field keyboard pops up -> hit back click on text field -> keyboard no longer pops up
After that going between the screens and clicking on text fields does not work (i.e. the keyboard doesn't pop up). It works fine if I use default transition.
Any ideas on why this is happening?

I'm not sure this is your problem, but your storyboard setup is wrong. It looks like you're going back and forth with modal segues. Every time you do that you're creating a new instance of the view controller you're going to, so you're piling up more and more controllers, none of which ever gets deallocated. Unless you're using an unwind segue, you should never go backwards in a storyboard with segues. So, when going from the controller you show on the right back to ViewController, you should just use [self dismissViewControllerAnimated:completion:] in code, and get rid of the segue.

Touching an area of screen dismisses view controller

I've never seen a problem like this until now. When I first updated my app, this problem did not exist. It was fine. Since then there've been a couple of iOS updates, so it's possible this is where the problem began.
I basically have a few view controllers that proceed like a wizard from one step to the next, by either clicking back/cancel button or the next button.
There's a textView covering the main area.
Normally by touching inside the textView it would begin editing.
On this viewcontroller it's fine, that works. No problem.
On this viewcontroller and every subsequent view controller including tableviews with options to select, if you touch anywhere underneath the cancel and next buttons inside the view controller, it dismisses the view controller and goes back to the previous screen. There doesn't appear to be anything executed in my code when this happens. It just dismisses the view controller as if one pressed the back button. I know the back button code is not being executed because I printed a line in there.
The next view controller is a tableView and does not have a textView. It's got nothing to do with the textView. It just dismisses if I touch anywhere on the screen other than the next or cancel buttons. The next views are the exact same way. It's like a big invisible button is in the way of the screen blocking any interaction with the top half.
What's going on here? How do I fix this? It has never done this before and I didn't change anything.
Turns out that this was caused by using page curl transitions. I changed it to flip horizontal and it works now. Page curl transitions are obviously bugged currently.

Swift - create a back button without navigation controller

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.

pop view controller with enabled/open keyboard in ios 8

i am trying to implement some chatroom-like view controller (e.g. Messages-app on iPhone), and i would like to keep the keyboard enabled/open when this (chatroom-like) view controller gets dismissed and therefore gets popped from the stack, BUT dismiss it together with the view, i.e. sliding it out of the screen together with the chatroom-view-controller.
For the desired effect, just open the Messages-app on the iPhone, go into one chatroom/conversation, set the focus on the input-textfield so that the keyboard comes up, but then go back to the last view without dismissing the keyboard.
I always get this weird animation that the chatroom-view (-controller) is sliding out of the screen to the right (which is desired), but the keyboard gets dismissed to the bottom of the screen...
Does anyone know what I am doing wrong? I have already tried it with so many versions, from become/resign first responder in all the different view will/did appears...
My assumption is that it could have something to do with my custom pan gesture recognizer for popping the chatroom-view-controller from the stack of the navigation controller, but neither the docs nor the web contain such issues...
you don't need to keep your keyboard visible, instead you can make snapshot of chatroom controller right before it being dismissed.
Edit: I just created simple app with navigation controller which pushed controller contains text field. Then on app tried to pop that controller when keyboard is visible. And..all view was dismissed together with keyboard, so your wanted behaviour is given by default.

UI keyboard not appearing when UI textfield tapped after model to a different view controller

Ok. So I have been testing out a simple application on xcode to become familiar with the platform, but I've come across an interesting situation. Using storyboard, I've dragged two view controllers that are connected by buttons by segues. They both have a uitextfield dragged on them that respond on click when they are the initial view. However, when I move to another viewcontroller from the buttoned segue, the keyboards no longer automatically popup. Is this a problem with apple's uitextfield? (ps. there is no code to this as I thought this would simply be automatic responding)
Look to see if the view hierarchy has become messed up. You can easily see this in the 'document outline.'
If you don't see this pane, look on the left, bottom side of the storyboard and click the small arrow pointing to the left.
What do you see here? Is the Text Field an immediate child of the View or of something else? If it's an immediate child, do you see other children of View listed here that you don't recognize?

Tabbar not showing in ios application

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.
