I'm trying to write my first iOS app, but I'm having trouble with a simple problem. I want to figure out what's going on... can you please write me a simple code which can help me a lot?
Let's say I have 3 different UIViewControllers. One is the MainPage which contains 1 UIButton: "Food" If I click on this the FoodPage opens which has 2 buttons "Pie" and "Pizza" if I click on "Pizza" the PizzaPage opens if I click on "Pie" the PiePage opens. Both of PiePage and PizzaPage have 2 buttons one for FoodPage "Food" and one for MainPage "Main".
Can you please write me a code or give me some idea how to do something like this?
Thank you!
Go into main.storyboard.
Lay out the views.
Hold option, and left click and drag a button to the view you want to have it show. (If you have a mouse, you can right click and drag the button to the view)
The Action Segue options should show up. Hit "show". Now you're button will load that view controller.
Below I am dragging the cancel button to show the previous view controller.
Good luck.

Something strange is happening in my app. I'm finding that when I press any button, all of the other buttons on my view are getting pressed. They all seem to be linked somehow.
There are no outlets connecting them to each other, they're not linked to the same function or anything. I can't figure out why this is happening? Any ideas why pressing one button will trigger a touchupinside event on another, unrelated button?
Thanks
I bet you created a button, added an action to it, and then duplicated it, dragged the copy to a new location, and added an action to the copy. Then you continued with that process.
Go to the "connections inspector" tab on the right (The circle with an arrow on it). Select each button. I'm guessing that you have multiple actions on each button. (A button can contain multiple actions.)
I', struggling with such issue- I can't add back-button to the last tableViewconrler.
When I'm tying to drag nav. item, but nothing happened.
How can I make this famous checkmark back element?
What they mean is your storyboard should look like this.
The title won't clear the actual problem. Let me explain clearly.
I have a tabbarcontoller in the viewcontroller which is the main view controller of the single view application project.
I added Navigationcontrollers to the tabbarcontroller. So that I can navigate(push/pop) from one viewcontroller to other.
I added a subview to the mainview of a single navigation controller.
When I click the button near to the tabbar, it doesn't get clicked and the tabbaritem button gets access and shows that tab.
The below image will explain well,
If I click the show button, it opens the receipts tab.
How to reduce the click access boundary of the tabbar in tabbarcontroller?
I can't get any solution regarding this.
Frankly, i've written a bunch of applications which have controls near the tab bar and i've never encountered such behaviour.
Check if you have custom tabbar controller with custom frame.
Also try to use Reveal App (http://revealapp.com/) to check the buttons' frame at runtime, it will help you to understand what's going on. They have trial version as i remember.
Hope it will help :)
Choose the custom button for this and add in tabbar.
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)
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.
