I am wanting to know how to pass buttons between two view controllers. As an example when you click "move" on one view controller the button will appear on another view controller. I am wanting to know the code to do this task. Thanks.
Perhaps just make an identical button of that button. When you click the "move" button the next screen will have the "move" button. Except this time it will have the functionality of your choice!

There are 2 extra buttons on my storyboard tab view controller and I haven't connected anything yet. They only show up in run time and there is no code adding buttons to the tab bar controller.
Do you know where the buttons are coming from?
Delete the tab view controller then add a new one and redo the connections.
I wonder if someone could help me please? I'm brand new to iOS and whilst I've been searching various sites for my answer, I'm afraid I haven't come across it yet but feel this could just be my naivety to the language so I apologise if this is a really simple thing...
I have a Tab Bar Controller with 3 views. On my first tab I have a button which when clicked, I want it to go to the 3rd tab (which is does). However, on the 3rd tab, I would like to insert a back button so that the user has the option of clicking back to go back to what is essentially the main menu of my application.
Can anyone tell me how I can do this please? I'm currently using storyboarding as I'm not very good with the language yet but any help would be greatly appreciated.
Thanks

You need to add a navigation bar to the view and set a bar button item with the action to change the tab.
Remember that a tab controller is standard across multiple apps, the user is use to tapping the tab to change the view rather than pressing buttons within the view.
It might be worth you looking into a UINavigationController
The first thing, you are implementing UITabBarController. you don't have to create a back button, because user can navigate between screens by tap on tab bar.
Second thing, you can use UINavigationController to manage you viewControllers,the Back button will automatically show when you push ViewController by method pushViewController:animated:
I have one empty view and some actions on the view toolbar. When I click any of the actions, I need to show one button on the view. so we can it is some kind of dynamic rendering on the view.How do I do that?
I have made a small example on how to create the toolbar, the handler and button in the view... See so-viewaction.zip. Hope it helps.
My iPad (!!) app has a table view as the UISplitViewControllers details controller. To trigger various actions I use the following:
A swipe gesture on the cells to make a button visible that is called "Action".
Touching the action button shows a UIActionSheet with various options (Delete, Send, Download).
Touching one of the buttons in the action sheet triggers the action.
To achieve this behavior I customized the title of the "Delete" button which would normally be shown by the swipe gesture.
Please note that touching the cell itself will open/preview the touched item.
However, my test users complain that they cannot find the action menu because they would never try swiping the cells and if they would, they would do it to delete the entry. But they like that touching the cell previews the item.
Hence my question: what is the correct way of doing it? Show a disclosure button in every row (the little blue arrow to the right)? Show UIBarButtonItem in every row to bring up the action menu?
I'm so against it because it looks ridiculous to have a button in every row.
Sounds like a tricky situation; I'd either:
Add a detail disclosure button to each cell, and have that push a new view controller with the options (like the YouTube app).
Show the options in the "entry" view and have the "swipe" action an extra, discoverable feature (like the Twitter app).
I have a navigation controller in my app and on its root view controller i have an Edit button as the rightBarButtonItem.
I have a second table view which is pushed when a cell is tapped on the root view controller.
The leftBarButtonItem becomes the Back button.
I would like an Edit button as well, where can i put it that would make the most sense? My rightBarButtonItem is a + button, so that rules that out.
I would like to be able to tap a cell and change the cells text.
Thanks
The easiest thing to do is add a toolbar at the bottom that contains an edit button.
You could also try adding a bar button item with a custom view that contains two UIButtons and set it as the right bar button item of your view controller's navigation item. I haven't actually tried this, so I don't really know if or how well it would work.
