I'm a relatively new developer. I'm trying to push a new view to the screen when the user selects one of the barButtonItems without it being a navigation controller. I know how to do this for selecting a cell in a table, but when I try the same techniques on the barButton, they don't work. Can anybody help me?

I'm developing a game in xcode 5, and after a collision I need to change the view
(it's a new view, not the previous, nor the rootView).
Is it possible to do this without using segues?
Here's a couple ways off the top of my head:
You can use UINavigationController to push another view into the user's view, or you can do a "presentViewController:".
I have seven views that I need to navigate between from any of the other views. I don't want to keep doing segues from each one as new instances would keep being created...among other issues. What I was originally trying to do was have all the segues start from a home view and then go to the designated target view. When the user left that target view a public variable would be set if they wanted to go to any other view other than the home view. When the home view reappeared, it would check that public variable to see if another jump was needed. In the Home view I put the segue jump check in the -(void)viewDidAppear:(BOOL)animated function. The problem with this being you see the home screen for a second before it goes off to the new target view. The -(void)viewWillAppear:(BOOL)animated does not work for segues. I guess this is because it hasn't fully released the old segue yet?
Is there a better way to handle a freeform many view navigation issue like this? If anyone needs it, I can post some sample code for what I was trying to do. Thanks in advance for any help.
It sounds like you need a UITabBarController.
It allows you to have multiple view controllers, and switch between them by tapping the tab on the bottom of the screen.
It allows you to have only one instance of each controller, so that as you switch between them, data persists and you aren't creating new instances each time.
Here is an example of what one looks like (notice the tabs at the bottom of the screen):
(source: xamarin.com)
First off this is Xcode 4 iOS 5.0. Here is what I want to do. I have one view, we will call it view1, which has a button and when that button is pressed a different view with a table appears called tableView. I have multiple images I want to be in this table and when the image is selected, it would appear in view1. I have already researched all of this and just can not find the right material. The button and table are already working together and I can add the objects to the table, but getting those objects that I select to appear on view1 is what I am not understanding. I can not get the two nib files to work together, or Im going at it wrong.
Second question, guess this is similar, view1 displays an image that is selected from the photo library BUT is there a way to open the photo library, select the photo, and have it appear in a DIFFERENT nib view? Again this is getting the NIBs to work together. I would appreciate all the help I can get. (photo library and selection of photo already works so that code is not needed). Thank you for the help!
I have used this example to get what you have described in the above question. But with some tweak in the delegate methods and hop you will get some direction for your problems, too.
Good Luck!
Happy Codding! :)
And need any help just ask for it, don't hesitate.
It is possible from delegates in other class.
I had a question previously that died out and wanted to post a different approach and see if it was possible.
I have a working application that has a UITabBarController that controls 4 distinct UIViewControllers. I am able to navigate fine through these, but a couple of the loaded views need to load others in order to perform actions.
Is it possible to have a button within a UIViewController that will replace the current view with a different one and still maintain the tab bar on the bottom? possible replacing the current view and advising either the new UIViewController or the owner tabBarController that the relationship is still the same?
I can post code and further clarify if you wish. I am VERY new to XCode so i'm not completely familiar with how everything operates as of yet.
thank you in advance,

Yes you can add new view to one existed in the tab.
For example, if your view controller in tab is of type navigation based then you can push the other view upon certain event.
Im wanting to create a generic dropdown control for my IPad app. Basically when the user clicks on a textfield a popover control will show and list items. The users can keep typing in the textfield which will filter the items in the dropdown popover control.
Has anyone got any advice or know of any examples on accomplishing this?
Basically it will be like the "Suggestions" popover list in the App store search field of the ipad.
Thanks in advance
Well, I would accomplish this by loading a TableViewController into the PopoverController and make its interface available to the ViewController (the one that has the textfield in it).
In the TableViewController I would load a dictionary/array of items. Whenever a user enters text in the textfield (you can respond on this trough events in your Interface Builder) I would then call a function in the TableViewController that updates the list that is displayed (e.g. displays all dictionary items that start with the entered text).
Whenever someone clicks on a item in TableViewController, you can then call a function in the ViewController.
I can't give you a code sample, since that would require quite some time to create :P.
I hope this helps you.
