Iphone like password interface - iphone

I am new to Iphone programming. I want to add a password module to my application with look and feel as iphone's "Enter Passcode". Is it possible. I earlier tried this by using four text boxes and allowing allowing to enter only one alphabet in each.
This had the problem of cursor in the text boxes. So i disabled all these, took an invisible text box. Allowed user to enter passcode in it. And copied the text in each of those disable text box on textediting event. This works as required. However the last text box of the four never displays text. Is this because i have chosen text editing event. Please help.

There's a Google Code project that has implemented this pretty nicely:

Hope this helps!

You mean the 4 number pin pad?
I implemented something similar
xib file with 12 UIButtons 4 UILabels and 4 UIImageViews.

Multi line uitextview

I was hoping I can get some help with creating a username and password box similar to the one Yahoo uses on their iPhone app. It seems to have a separator in the single textview box. I'm still new to using Cocoa so I still have a lot to learn.
I have attached an image of the screenshot I took.
Thanks!
Screenshot
The Yahoo screenshot shows what looks like a grouped UITableView with two cells. The separator is the line between the cells, and each of the cells would contain a UITextView.

Login textbox style - iPhone

I have a login screen with a username and password textbox. However, I've come across a better way to present my username and password textboxes.
The textboxes seems to be merged. Just like the login screen on Windows Live Messenger iPhone app.
Does anyone know how to make this?
Thanks.
Better You can also use Grouped UITableview, add two UITextfields into the tableview cells as subview. This should be look as same as windows live messenger.
That is a UIView containing 2 text fields. You can have an UIView, give it background image and place 2 UITextFields on it.
You can take two text boxes with none border style and then you can place a back ground image as you need.. This may be the solution.

How to center text label in iPhone Settings application

When you look at Settings - General - Keyboard you can see text "Double tapping the space bar will insert a period followed by a space".
Question: how can I do something similar in my own app settings?
Got pretty close by using PSGroupSpecifier for text, but can't figure out how to center the text. Centering is the missing feature I'm now looking for.
No, you can't do that with AppStore Settings bundles.
You can fake centering by inserting a lot of spaces at the beginning.
(Centering the text is restricted to internal "preference bundles".)
changed for ios 4.0 - > make use for the footerText field of a group specifier.
follow:
http://developer.apple.com/library/ios/#documentation/PreferenceSettings/Conceptual/SettingsApplicationSchemaReference/Articles/PSGroupSpecifier.html#//apple_ref/doc/uid/TP40007009-SW1
all you will need is in there.

iPhone keyboard layout for negative numbers?

My users need to enter latitude and longitude, and of course I need to verify that the values entered are legitimate lat/long value. I'd like to have a keyboard layout that does some of this for me (eliminating alphabetic characters, punctuation, etc, and leaving only the numbers and +/-). The number pad keyboard doesn't seem to do it (missing +/-) and neither do any other keyboard layouts that come with the SDK. Does anyone know if there is a way to provide that capability without doing my own keyboard IME and jailbreaking the phone?
Thanks!
I know this is answer is way late, but this topic was still relevant to me. Therefore I have hope the following will help someone who comes across this page.
Bryan S. Gruver posted a full Xcode project that lambdabunny could modify ever so slightly in order to achieve their aim. You can find it here:
http://brygruver.squarespace.com/blog/2009/10/1/creating-a-custom-number-pad.html
Update
The Squarespace link is now broken. Another option is:
https://github.com/lnafziger/Numberpad
How about placing a "+/-" button next to your UITextView that would switch the sign of the entered text? Or a "+" button that appears to the left of it that switches the button label from "+" to "-" each time you tap it.
You don't have to jailbreak.
If you create a view to simulate the keyboard you're still following the SDK rules.
