I am looking for a way to use the standard iOS image resources through my application. For instance I would like to place the DisclosureIndicator icon in an image view of mine. How would you go about using the standard resources in iOS?
I believe it would be considered a private API to use iOS resources within your app but I would check out this project art work extractor which will allow you to extract art from existing native iOS applications and you can include them in your project. Be sure to run this in the retina version to get the #2x versions.

I want to develop an application in which I capture an image of text (a business card, for example), and now I want it to be scanned and converted into an editable text. Is it possible? Something like optical character recognition.
Here are some examples
OpenCV library for Apple iOS. It includes two XCode projects: one for iPhone, the other one for iPad Try OpenCV with iOS
demo application that utilizes the Tesseract library as a static library compiled under Mac OS 10.6 Try Tesseract with iOS
And Here is good question realte to this.
Hope this information should be useful for you.
Thanks
i'm searching about image filters using ios5 sdk but i have two questions:
For Mac Os X seems to be a lot of filters that are not available in IOS SDK. Is it possible to implement them or have they already been implemented?
Is there an open-source library with filters like Instragram uses?
Thanks!
Core Image on iOS lacks many of the filters that are present on the Mac, such as blurs and other more complex operations. You also cannot write custom filters in Core Image as of iOS 5.1.
My newer GPUImage framework lets you write custom filters, and it has many of the ones missing from Core Image on iOS, such as unsharp masking and edge detection. It's also much faster than Core Image in most cases. I built this framework specifically to address the current shortcomings of Core Image on iOS.
You can create your own custom CoreImage filters by implementing your own kernel. The kernel will be applied using CoreImage's hardware acceleration, see: Creating Custom Filters
There are a number of open-source image libraries. We use ImageMagick in some of our iOS apps. A iOS library is even available for download.
you can use this open source library based on c/c++ , and this is the library link
Is there a way in PhoneGap to download & save a binary file (I'm specifically interested in mp3s) that works across both iPhone and Android?
A web search reveals a plugin for Android:
http://www.toforge.com/2011/02/phonegap-android-plugin-for-download-files-from-url-on-sd-card/
And some code for iPhone:
http://blog.clearlyinnovative.com/post/1097750723/phonegap-plugin-for-downloading-url
But nothing that covers both.
PhoneGap has evolved & added this functionality.
I would suggest that you write some lines of javascript code to hide them both behind the same interface (you will have to provide different storage locations anyway)
Their interfaces look pretty similar already
I've noticed that the icon belonging to the Calendar app on the iPhone updates to show the latest day. Is there anything in the SDK that will let me do this in my apps?
It's not possible for third-party apps, unfortunately.
I've never seen this in any documentation, pretty sure it can only use the static icon.png file that is put in the ipa package. It would be an awesome feature though, I would recommend creating a feature request for it on https://bugreport.apple.com/. I specifically wish the weather app would update with your local weather for the icon.
I want to used the particular fonts for my application. But I don't how can use that font that are in the iPhone SDK library.
Any idea how can I do this ?
By the way I want to use hindi and punjabi fonts in it.
The FontLabel open source project provides a means of drawing your own .ttf fonts on the iPhone.
There is currently no official way to do this; but given the presentations of iWork on the iPad, it's possible that the 3.2 SDK adds this.
Edit: Assuming Jasarien is right about this; you'd probably be better off developing for iPhone OS 3.2; as you'll need an iPhone Dev Central membership to publish your applications at any rate; you might as well get started right away.
