Image Editing Issue - iphone

I am working on an app with have requirement to give "Droste Effects" on image.i did search on Google more but not find programming solution for this effects.the effect example in there below.

Please provide me suggestion or any tutorials link. How i will do that task?.Thanks in advance.

The Droste effect is a trick made with some intense mathematics and a recursive function. Please read http://www.josleys.com/article_show.php?id=82. If you don't know about recursion please read up http://en.wikipedia.org/wiki/Recursion. Since your request is very specific I doubt there will be many people who happen to have a Droste effect code written in the iphone programming langauge, but the links above should help you understand the math behind creating your own. Good luck.

adding Contact/Number into Textview/textfield like default MessageComposer did

As like my other questions I tried to search for this. But I didn't get anything.
Maybe my path is wrong. Please direct me.
Here is my Question : I have a UITextView. In that I am going to add Numbers, Names and contacts.
I want to show each number separately as MessageComPoser did.
Does anybody know how to make this?
If my question is not worthy, give me the correct answer then downvote.
(For my questions somebody downvoted without even giving any answer!!)
There is no way to do this using apple's native framework, they didn't provided any controls for doing the same.
You can use the TTMssageRecipientField provided by Three20 framework.
I found the Answer. I don't want to use Three20 library since it is Very difficult to use in my project.
So i Found Awesome Link. That gives me the answer.
I used this Code It May HelpFull To many users, specially for those who Upvoted This question.

Highlighting Text in pdf using iphone SDK?

I had asked a question earlier How to Searching String from PDF using iphone sdk?
I got a answer but that wasn't I was looking for. I am not sure to ask something similar as new question or not.
I am using ios4.2.
I am working on a application which display PDF. I am using Quartz 2D for that. I have gone through apple documentation and googleing of around 4 days I didn't find any thing that suits to me in this case. There are lots of question related to this and almost all answers are redirecting to either
Random Ideas or
FastKit.
Random Ideas don't explain how to highlight a text within the pdf. and FastKit has implementation but no Explaination too. I don't want to use fastkit because It shows its logo. can any one please give me any link which has some libraries or apis or any thing for highlighting text in PDF while I am using Quartz 2D.
Any help will be appreciated.
Thanks In Advance.

How to read the text from an image in iphone

i want to read text in an image how to do that...
Thanks
What you’re asking about is called OCR, and it isn’t as simple as you might think. Luckily, there is at least one open-source effort to do it.
You need an OCR library, see this question for further information. For a more specific answer, you might want to post a more specific question.

jqTouch & Documentation

I'm playing around with jqTouch - a very impressive project - however, I was wondering if there was some systematic documentation I could get my hands on?
The website gives some demos, but I'm finding it very slow going having to look through the source code to figure out what class I should assign to my divs, lis, etc.
Anyone got any pointers?
Thanks in advance,
There is no real documentation per say, however check out
Best article about how to use jQTouch
for some useful tutorials.

Is there a good iphone sdk documentation site that provides good examples / common usage?

The problem? I look up stuff in the xcode documentation and find very useful lists of objects, methods, etc... But then I still have to go somewhere else to find useful example code of how to use that object. For example, I looked up NSNumber yesterday and found all of the neat stuff it can do, but I still had no clue how to use it. That's just an example. I'm sure I could read the objective c pdf front to back and learn something there (which I plan on doing) but what about later? When I'm looking up some UIKit object? Do I have to go find a tutorial each time (or lately, I just ask StackOverflow and you guys take care of me).
Is there a part of the apple website / xcode documentation that shows the example code I'm looking for?
Is there a wiki site out there or something that has what I'm looking for? (I just tried a simple google search "iphone sdk wiki". this site could be good. iphone sdk wiki . I'll check it out. Anyone else have one they like? )
This is also sort of a mild complaint to Apple. Why not a section on each code definition page that shows usage?
I've found the sample code section on Apple's iPhone Developer Connection be extremely useful not only for samples of complete applications but also a best practices source. Going through the code of The Elements, for example, will expose you to how to use particular classes as well as how to structure your code. It is a wonderful example of how to create a non-trivial iPhone app.
Look in developer.apple.com/iphone they have pretty good documentation (you can use the search bar there) on all the classes and have a lot of good sample code..
I really would emphasize the "Related sample code" section on many, if not most, of the documented classes.
But, IMHO, there isn't any easy way of acquiring the knowledge to develop in Cocoa/Cocoa Touch. The API's are so numerous that it simply takes a lot of time and experience. You just have to work on it, look at a lot of books and study the sample source code where available.
I've tried to take a purposeful approach by carving out some time every week to learning a new API/class irrespective of whether my current project needs it or not.
Alternatively, search Joe Hewitt. He's the developer for iPhone facebook. He has a project you can download that demonstrates all the features of facebook. It's an awesome open source project!
When you look something up in Xcode Developer Documentation, you sometimes get a Related Sample Code: text that tells you what Sample the method or property is used in. Too bad you can't click on it to see the code, but if you do click it takes you to the page to download the sample. – mahboudz 0 secs ago
Apple Developer site has all kinds of code examples. Try searching google for a UICatalog project, it will show you all the basic UI stuff you can do, like adding buttons and progressbars through using only code.
