UIView accessibility issue - iphone

I've developed an iPhone App and most of it is accessible but I have an issue with one thing I do.
When the user clicks the settings button in the App (it has a main menu with a bunch of buttons for various Applications) I add a UIView on the top and and darken the background screen. Unfortunately for a blind person this UIView doesn't become "active", ie they are still navigating around the background screen.
I initially added the UIView using addSubview: and then tried insertSubview: atIndex: but neither have operated as expected.
Edit: Further information there are text fields and a button on this screen, perhaps I could instead make one of them active or something?? No idea how I would do this though.

How about using becomeFirstResponder? It makes the control receiving this message active and the receiver of input. For UITextView etc. it brings up the keyboard.

I didn't get what you are saying, but I thought there may be problem with the view added on the top.
Do one thing, if you added the view using interface builder then select the view and click on Layout menu in the Menu bar and select "Send to Back".
or else if you add that through code, then write code as
[self.view sendSubViewToBack:addedView];

How to tell VoiceOver that a control has animated away?

User taps control and a different view comes up, animated. VoiceOver still highlights the removed control and it is stuck. User can't interact with the view.
This is not in a UIViewController but a custom UIView subclass.
How to tell VoiceOver to update its presentation or state when something appeared or disappeared with animation?
You can post an accessibility notification to indicate that the layout or the full screen of content has changed and select a new element.

How to change UIActionSheet view?

As I observed that UIActionSheet is always appearing from down side in iPhone,
but in some app, as I saw in AlarmClock, then two button became visible, one from upside and second from downside of iPhone,
What is that exactly, I can't understand, as far as I feel, it looks UIActionSheet,
I want such appearance for one of my app....
Help!
Yes just like Ole said, you can't customize UIActionSheet . But since it is just a simple subview you can create your personal "action sheet" by subviewing and animating. So if you want a button to appear on the top and one on the button, then create two UIViews resize them to the right size for your button, add your action sheet style background or any other background, add your button, connect your IBActions to the buttons and your IBOutlets to the views. Then when you want the buttons to appear animate them onto the screen (using sone CGRect, animation time and finally [UIView commitAnimations])
Probably just one or two custom views with a custom animation. UIActionSheet is not customizable so if you want something else than the default behavior you have to write it yourself. It's not that difficult.

Can my custom tabbar be created like so for iPhone?

I have designed a custom tabbar and the developer says the design I created can't be done.
The screen is made up of a usual background with a tabbar. I'd like my tabbar to look a little different to the usual iPhone style. I would like at the bottom of the tabbar a grass illustration (transparent) and on top would sit all the separate buttons and on top of those would be the icons. All of these images (as seen in link below) are separate .png files.
When the user scrolls the content, it will scroll under the transparent grass. The buttons of course will be clickable and have a different view for an active state.
Please see the link below to see a mock-up of the image:

I'd appreciate if the community could explain to me if this could be done and if so, how. I thought it would have something to do with 'creating a custom tabbar'.
And a further question, if it can be done, can also the tab buttons be horizontally
scrollable with a swipe action?
Thanks,
It all can be done but you are going against the Iphone UI guidelines. You won't be able to leverage the UITabbarView to do what you want so you'll basically have to write the whole thing from scratch. Your tab bar would be a scroll view with a row of buttons representing each tab. When a button is clicked you load in the appropriate view. The UITabBar controller gives you a lot of functionality for free and I suspect once you start working towards this you'll see exactly how much extra work this will end up costing you. Going against the way Apple does things can be a slippery slope.
Another idea might be to keep a hidden UITabBar to manage the tabs and call it from your custom tab bar. This would free you from a lot of the hassle of swapping views/controllers in and out.
You can create a row of custom buttons and have 2 subviews. One for the bottom navigation bar and one for the content view where you will be swapping your content based on what is pressed.
You can have a state which maintains what was clicked. Based on that you can set the button enabled state for every button in your bottom bar.
button.selected = YES
It will be easy to handle the touch up inside events and properly load appropriate views in and out of the bigger subview as they will be part of the same view controller.
I have implemented a similar functionality and it works well but still in process of submitting it to the app-store.

iPhone UIActionSheet with UISwitch and UITextField

I'm just looking for advice with this as I have no idea where to start but I think a UIActionSheet is probably best.
What I'd like to have is a pop up window (in my head I picture it as being translucent and dark gray). It will not take up the whole screen and the view underneath will still be visible.
In the pop up section there will be a textfield (with several lines) and underneath this there will be a number of UISwitches.
The pop up will be scrollable and will end with OK/Cancel buttons at the bottom.
Like I said, I really have no idea where to start with this but any advice is more than welcome!
A UIActionSheet is probably not what you are after in this case (although you may want a similar look and feel). Think of an action sheet as a traditional modal OK/cancel/Yes/No type dialog box:
Use the UIActionSheet class to present the user with a set of alternatives for how to proceed with a given task.
From the sound it of it, you need to create a UIView in InterfaceBuilder with a semi-transparent background and various child controls (UISwitches and UITextFields). You create your view using the XIB you have configured and add it as a subview of your UIViewController's view. If you want to mimic the animation you get from an action sheet, you can do that with an AnimationBlock.

How to create a full-screen modal status display on iPhone?

I'm trying to create a modal status indicator display for an iPhone app, and would like one similar to this one used in Tweetie:
Specifically, this one "shades out" the entire screen, including the toolbar. I don't believe through any normal UIView manipulation, I can extend past the bounds of my window, can I? I believe I've seen a status indicator like this somewhere else on iPhone, possibly when I added an Exchange e-mail account.
I've tried subclassing UIAlertView and overriding its drawRect method. If I don't call [super drawRect:] it doesn't ever display the normal UIAlertView text box, however my drawing rectangle is in an odd size and position.
Anyone have any advice to accomplish this?
Check out MBProgressHUD.
Take a look at the source code to the WordPress application. They have code which you can basically drag and drop into your application to do this.

I haven't done this myself, but you could layer a UIView at the top of the view hierarchy, and use setHidden to dynamically show or hide it. Since it's at the top of the stack, it should be able to intercept all touch events.
