Hey,
I want to be able to reproduce this effect that when clicking on one of the button in the menu, a view or viewController appears under the menu controller before the uitableview just like in the MarioCooks app. I have been trying inserting a subview below a subview, but I can't seem to get it right. Please need your help. Sorry I would have provided pictures, but being a new member I have no right to. Thx
Try UIView's insertSubview:belowSubview: method.
If you don't want it to be directly below, you can use insertSubview:atIndex:. A view holds an array of its subviews; you can through the (readonly) NSArray property subviews.

I have one UIViewController with two UIViews on it. In the Navigation bar, when one button is pushed one of the UIViews is displayed and when the other button is pushed the other UIView is displayed. I want to put a UITableView on one of the views. However, the UITableView requires the UIViewController to use the UITableViewDelegate and UITableViewDataSource. Having implemented this for my UIView (subview) containing the UTTableView, when I click on the button for the other view, which does not contain a table, I get errors and the application croaks.
I am assuming (possibly incorrectly) that my issue is that I am trying to use the same UIViewController for both subviews, but only one contains a table.
Question 1) Is it possible to do what I described above? Meaning, if I had a problem then something was not connected up correctly.
So, I went down a path of creating two separate UIViewControllers; one for each view. Not sure this is the smart approach. Now I am just looking for advice on the best way to do this. Thank you in advance for your help.
To be more clear about what I am trying to do. I want the blue view to be put where the pink view is when the first button on the bar is clicked and I want the yellow view to be put where the pink view is when the second button is clicked. Essentially the pink view will never be displayed and may not even need to be on the UtilityViewController.
Having each as a UIViewController (or a subclass thereof) is the way to go about what you are trying to do. The UITabBarController does this already: https://developer.apple.com/library/ios/documentation/uikit/reference/UITabBarController_Class/Reference/Reference.html
I'm having a strange issue with my UISearchDisplayController. When the search display activates the frame of the background fading view and the tableview are incorrectly overlapping the UISearchBar. It appears the results tableview is not taking the offset for the UIStatusBar into account.
The ViewController is using auto layout. Since the application does not use any opaque bars, the view controller does not extend any of its edges.
Extend edges under top bars = NO,
under bottom bars = NO, and
under opaque bars = NO.
Here is the initial layout:
This is what happens when the search display activates:
And finally, here is the resulting output of the search:
I solved my own problem. A hard lesson learned. After a few hours of thinking "It really shouldn't be this hard." I realized that my instance of UISearchDisplayController was not properly linked to the API provided property of its parent view controller. If you're using UIStoryBoards / Interface Builder be sure to click on your ViewController and view its provided outlets in the inspector. If you see this:
Then something is wrong and you're going to run into issues just as I had. What you'll want to do is to click in that empty circle and drag to your instance of the Search Display Controller. If things are linked up right you should see this:
I foolishly didn't pay attention to this and created my own IBOutlet to reference the Search Display controller. That caused IB to null out the API provided outlet as a UIViewController can only support one Search Display Controller. If you need me to clarify anything let me know.
I am newbie for iPhone application. For storing data, I am following this tutorial.
I understand how to save data and retrieve the same.
What I am wanted to do is instead of another UITableViewController (first screen in storyboard, where we have list), I will drag a UITableView and show list of items there instead of showing in another screen.
Any idea/ suggestion how to get this done?
Any hints would be greatfull.
What I feel is, I would need to add UITableView. Add delegate and dataSource method on it and add a method where I will have all data shown in UITableView.
Edit 1
What I want is ONLY ONE SCREEN. In the link that I have provided, it is second screen.
That should work fine. But make sure you also have done a
[tableview reloadData];
after you've changed the data in your table view data source delegate.

Why you want to do this way?
UX will not be at best.

Even if you want to do, yes you need to set delegate and datasource methods.
Ive a project close to doing everything I need it to do. Its got a Main page which has four buttons that allow you to choose an option. Then a tableview page is launched from those options and displays a parsed XML feed from a website. You can then select one of the options in the table to see a detail view of the item, enquire about it, etc.
My problem is I need to add more elements to the TableViewController page, other than the tableview itself. I want a customized back button (not the navigation controller standard) plus some labels, images, etc.
In the TableViewController xib, the tableview itself fills the page. I cant resize it to add more elements above it. I can add a 'view' window seemingly above the tableview and put things in it. But it seems to add the view to the tableview. This means that when I scroll the table, the other elements like new back button, scroll away as part of the table.
So I'm led to wonder whether I need this page not to be a tableviewcontroller, but a viewcontroller, with a tableview inside it, as well as my other view with buttons, etc. Is that the right way to go? But if thats the case, then how do I instantiate the tableviewcontroller within code? Because my page will not be of that type anymore - it will be just a viewcontroller. But in code Im making a tableviewcontroller .. slightly scared by that route tbh.
Any illumination on this would be much appreciated, as various searches have left me none the wiser. Thanks.
To customize it, this is the way to go:
Change your class to be a view controller instead, which implements the TableViewDelegate and TableViewData Source protocols.
In the view didLoad of you controller, create the table view, set its delegate, data source, and any other properties you wish and add it as a subview to your view.
tableView = [[[UITableView alloc] init] autorelease];
tableView.delegate = self;
tableView.dataSource = self;
// .. Other customization
[self.view addSubview:tableView];
I suggest doing this programatically rather than IB.
Instead of a UITableViewController, you want a UIViewController that has an IBOutlet UITableView. Drag and drop a UITableView component from Storyboard and hook it up, and position it as needed on the screen. This UIViewController should implement the UITableViewDelegate and UITableViewDataSource methods.
Edit: Remember that a UITableViewController is just a subclass of UIViewController so you don't really have to get rid of all your code. :) You only need to make minor tweaks to your header and main file, and change the Storyboard to be a UIViewController instead of UITableViewController as I mentioned above.
I checked out Apple's example on how to exchange detail views in the UISplitViewController and it seems that they put the UIToolbar in every detail controller. Then, if the device is rotated, they hide the toolbar or show it and add a popover button which will show the root controller.
I'd like to adopt this pattern to show my root controller in a popover using a button in the toolbar, but unfortunately, my detail controllers are all UITableViewControllers and they do not allow adding other UI elements than a table view. So how do I deal with that? Is there an example around?

I think I figured out by myself: DON'T use a ´UITableViewController´ and a UITableView as root view in your NIB, as you cannot add a UIToolbar to the table view.
Instead: In the NIB, put a standard view and drag a UIToolbar and a UITableView on it.
Connect the standard view to the controller's "view" outlet.
Add another outlet and make it a UITableView. Connect the table view to it.
In the code: Let your controller inherit from UIViewController and not from UITableViewController.
Add a property to your controller to get the TableView to make it look compatible to UITableViewController.
public UITableView TableView
{
get { return this.viewTableView; }
}
Upon the viewDidRotate event you will have to adjust the table views width and height now (UITableViewController did that job for you before):
this.TableView.Frame = new RectangleF(0, 44, this.SuperView.Frame.Width, this.SuperView.Frame.Height);
The 44 pixels com from the parent view's toolbar.
I don't miss UITableViewController. I know there are some issues like automatic scrolling when editing, but in my case this is simply not needed.

Check out this example and the corresponding code. If I understand your question, this should show you how to do what you're looking to accomplish.
Also, just as an FYI to everyone, another MT user MonoTouched the MultipleDetailViews example that you linked to above.
