iTunes U style download/progress/stop/play button - iphone

iTunes U for the iPhone has these wonderful buttons that show
the download progress
the stop button and the
play button (well, the "i" button)
in one place - see attached screenshot. Is this a system icon which can be called by code, or is it something thats not available for developers?
Anyhow: if someone has a source, that describes how to get such kind of buttons, I'd be very happy. It's clear to me, that the icons are controlled by a state-pattern in view-controller.
Thanks in advance.

There is DACircularProgress on github, it looks just like the circular progress bar on the Facebook app, I think you can take that, modify it to put the stop button on top and change the color and use it. check it out:

Small popup for instructions... How?

I am trying to get a popup appear the first time an app is started. Just to give you an idea check the new version of foursquare. A small popup (like a comic) appear explaining where the checkin button is located. Then if you tap anywhere it goes away. I googled for the last hour but I have not found anything at all and I have no idea on how to do it.
Anyone can point me in the right direction?
Thanks in advance,
Umberto
You can show a customized UIlabel on app's load and then use performSelectorAfterDelay: and hide the label inside this method. For the tapping thing you can add a UITapGesture on your view to notify if some tap's occurred and hide the label if it's still there.

iPhone UI Design: Okay button or no okay button

I am compulsive and like visually clean designs.
Theres a pop up in my app that tells the user that there's an error.
I made a clear button over the entire pop up (about 200x100 px) so the user can just touch the notification to dismiss it.
But i'm afraid the user might not know that you can just touch the pop up to dissmiss and would go crazy looking for the "OKAY" button.
Do you guys think the OKAY button is necessary or is a giant clear button overlaying the notification good enough?
note: the whole notification actually looks like a button because of rounded corners and some button like borders.
Whatever users can misinterpret, they will (just look at some of the low ranked App store reviews for examples).
So, unless it clutters your UI and/or makes things even more confusing, a clear indication of how get rid of or move beyond your popup will certainly reduce the chances for any user confusion.
I like the idea of your design, but I would go for an OK button. There might be people in the world who don't understand it and blame your app.
Or you leave out the button and make the notification disappear by itself after, say 5 secs.
Or you could go the Microsoft way:
- add the "Okay" button
- add a smaller checkbox with the caption "don't ask me again"
- when the okay button is clicked and the checkbox is marked, open an additional dialog notifying the user that the Okay button will no longer be displayed, but that they can clear that setting in the preferences menu
- create the preferences menu as described
Now who says Microsoft suck at UI ?
You should use the OK button. Not only will it be more familiar for users, but you won't have any problem with Apple's approval process. Depending on the reviewer they might reject the app for not conforming to the Human Interface Guidelines.

How to change text Cancel button Searchbar of iPhone in Titanium?

When I set the value 'true' to showCancel property in the method Titanium.UI.createSearchBar. It displays me the cancel button, but I would like to customize that button text to Go or anything else. How do I do that? Please give me suggestions. Thanks you so much.
I don't believe in Titanium Mobile SDK 1.4 you can change the button text.
As a work around you could add your own button to the screen and have it interact with the tableview. Not an ideal solution though.
Please find below the current documentation link.

what is the iPhone ringer alert popup name? and could implement that ? i mean like this :

It's not a built-in control, but there is an open source project (http://github.com/matej/MBProgressHUD) which creates a rounded translucent view. Although used for showing progress, it can be adapted.
It will take some tinkering with, but hopefully it's a push in the right direction.

How do I create a simple two-screen iPhone app?

I've gone through most of the example code and I still need some help. I want to make an uber-simple app: show one screen at startup with a label and a button. click the button and we slide over to another screen (I suppose these are called views) which has another label and the "back" button in the top menu bar. I just want to click back and forth between the two screens.
How do I do this?
Take a look at the NavBar sample on Apple's Developer website. http://developer.apple.com/iphone/library/samplecode/NavBar/index.html
You'll need to use a UINavigationController to accomplish the "slide"/"back button" behavior you're talking about. It is as simple as you might think, as long as the app is setup correctly. Essentially, UINavigationControllers allow you to push and pop instances of UIViewController or subclasses thereof, and take care of the animation and view history tracking for you.
The best way to get started, by far, is just open XCode, choose "New Project", and start with the "Navigation-Based Application." Dig around that project for a while and I think you'll start to see clearly what needs to be done.
You can checkout how to get started with that using this tutorial: at wattz.net
