Yes, anything is possible. There is no API for this, so you will have to design the component and its functionality yourself.

Difference between Icon properties in info.plist?

I'm working on an iPhone app and I'm not sure which plist property to use out of the following:
Could anyone shed some light on what each of them do and the difference between them?
Apple requires that you include an icon that measures 57x57 pixels. If you are just going to use that image, then you put it under the Icon File property.
However, Apple recommends that you include images of different sizes for different purposes, such as for the retina display, the ipad, and the search bar. If you are going to include multiple images, which will make your app look better, especially the retina one, then you include all of those images in the Icon Files property. Do note that you do not need the Icon File property if you are using the Icon Files property.
I am still developing for IOS 4 so I do not know about the Icon Files (IOS 5) property but I would assume that there are new places where your icon might pop up in IOS 5 where it will not pop up in older IOS versions. You would place those images under that property.
Hope that helps.

PNG within an iPhone app

I have the following issue:
My iPhone app makes some kind of graphics.
How can I save these graphics or drawings made by the app as a png file on the device?
Would it then be possible to set such a png file to become the icon for the app from within the app itself? (Provided the size is right of course.)
Thanks for any possible tip.
No, you can't change the app's icon at runtime (like the Calendar app that comes with the iPhone does)
How do I change the default icon of iPhone application programmatically?
For saving PNG images on your device, look into UIImagePNGRepresentation which is part of the UIImage Class.
As for changing the app icon, this would only be possible if you are jailbroken and have the right package dependencies that allow the icons to refresh in SpringBoard on the fly.
Outside of being Jailbroken, changing the app icon would require an app update which would include the new icon.
I wouldn't think it's possible for the actual icon for the app to change, because it's set on the phone when the app is installed.

iOS Delete Button - Objective C

I was wondering where does one get access to iOS delete button. This is the button that Apple uses to close the iAd window, and for deleting iPhone apps from the home screen, and also the Twitter App uses it to delete the photo that you add to a tweet. Do they just download this image somewhere or is there an option for it somewhere like for the info button, and the detail disclosure.
Thanks
I also found that Growl uses this icon along with Lion's Mission Control...
You can use UIKit Artwork Extractor to extract about any iOS artwork that is not public. Just search for close and you will find several close button png images.
Apple doesn't make that image available, unfortunately.
This iPad template has the icon you want, though, in a PSD: http://www.teehanlax.com/downloads/ipad-gui-psd/
If it's actually an image and the iOS Simulator displays it, it should be hidden somewhere inside the Simulator frameworks or support files.
What, you mean the circle with an X in it? It's pretty easy to make your own, either in an image editor or just drawing it in code. I can guarantee you that's what the Twitter app did.

How to make an iPhone view transparent?

I have developed a project that has a single view. Now I want the view to be transparant so that I can see the iPhone menu. Is this possible and if so, how?
Thanks.
No, you can't see the springboard in your apps.
It is NOT possible to do that. You can't make the whole app transparent so that you see the springboard icons.
Of course, you could set a homescreen screenshot as background image in your app. But, as already said, it's not possible to do that what you want.

Iphone working with icons

I want to write a simple program which can customize iphone icons like their positions or something like theme creators. and I want to know how some programs' settings are in the iphone main setting tab. I really need help.
thanx in advance
If you mean you want to retheme the springboard (the place where apps icons are displayed) you can't. If you want to retheme things inside your own application it is doable, but it really depends on the design of your application.
To get your apps settings into the Settings app you just need to add a Settings.bundle to your app, which a plist describing the preferences. There is documentation for it here.
There's an app that already does this for jailbroken iPhones. It's called iconoclasm, you can get it from Cydia.
