I'm developing a reader app for viewing and highlighting proprietary format documents. The documents are 2D. (Might add some cool page flip effects) The interface is similar to that of mobile safari. I have no prior experience with iOS development. Could you guys point me to the right direction? (Things I need to consider, tutorials, sample projects...) THX
developer.apple.com - it will take you a VERY long way. And then google whatever you need after that.
In itune U, you can download the 'iPhone Application Programming' course form Stanford University.
Assuming you're a registered developer, Apple just made all of the videos and slides from last week's WWDC available for free at http://developer.apple.com/videos/wwdc/2010/. There's an insane amount of very up-to-date info there.

I want to implement an iOS application which views PDF files. I have used vfr/Reader in some other applications before. But now i need to display multimedia supported PDF files on iOS which include videos, animations etc. My customer create these PDFs by using InDesign.
I made a research and can not found a proper iOS based framework to achieve this. There are really limited number of solutions like Adobe, FastPDFKit etc but they are so expensive and there is no "one time fee" option.
Do you have any open source suggestions or the ones with lower prices?
EDIT: Made a research for days and days but there is no solution. Is there any other tool to create interactive ebooks or magazines? May be HTML5 or something with editor itself???
I have used QLPreviewController before to open local PDF files and it works great and it not hard to implement-- and it supports multiple documents.
Heres a good tutorial that I followed:
http://mobiledevelopertips.com/data-file-management/preview-documents-with-qlpreviewcontroller.html
I have not tested viewing videos or anything-- the PDFs I had were simple. But it is an Apple control and has all of the basic PDF viewing functions like pinch to zoom, but like I said my PDFs only had text but it is worth a shot to try.
After a long long research and discussions, unfortunately there is no free solution with these features. There are only paid solutions and Adobe Publishing Suite takes the head although it is one of the most expensive solutions
I need to create an application capable to modify and manage files on IOS.
With IOS 5 is "easy" to create a Document-Based Application, but I need to support IOS 4 too.
Anyone knows if there is a way to create a Document-Based Applications in IOS 4?
Thanks in advance.
Short answer is no as UIDocument and UIManagedDocument only arrived with iOS 5
Long answer is yes. There are hundreds of document based apps for iOS. e.g Brushes, Sketchbook Pro which are all document based apps. My own app is document based, its not that hard to do.
What UIDocument/UIManagedDocument provides is a canned API for making a generic document. Feed it a URL and it does (most of) the rest of the housekeeping.
If you wish to do an iOS4 based app then stuff you will need to pay attention to is.
UIApplicationWillTerminateNotification/UIApplicationDidEnterBackgroundNotification
Opening a new document.
Saving a document.
Shutting a document.
Autosave (maybe)
Core Data stack , if you're using Core Data
www.raywenderlich.com has some great tutorials. Maybe even iOS4 based ones still.
IMO - Don't bother with iOS4 support. Like above post states 85% use iOS5 and anyone still on iOS4 probably isn't in your target market. Especially as this is (I assume) a new app and iOS6 will be around by the time you go to market.
Just going to ask, do you really need to support iOS 4?
The adoption of iOS is over 85% of devices.
Whats the basis for the need to continue iOS 4 support?
I am planning to build a BOOK APP (with text, images, animation, sound etc) for iPad. I started learning Obj-C But I came to know about frameworks like Corona & Cocos2D and Corona boasts to be promising for my scenario. I have no working experience with any of these but am willing to learn. Which one is better to start with for building a multi-media book app? XCode & Obj-C OR Corona OR Cocos2D and how would would be the learning curve?
I can't speak for Corona, but Cocos2D is just an Obj-C library, so you'll still have to know a bit of Obj-C to get it going.
That said, I started with just Objective-C, then found Cocos2D which greatly improved my development speed, as all the groundwork is already implemented. Cocos2D has a much more managable learning curve than doing it all from scratch, and there are a number of great resources available (cocos2d forums, this blog, etc).
A quick Google search showed me that Corona has costs associated with it for distribution - cocos2d does not.
I'd have to say Corona SDK is perfect for making a book app as you described. The basis for this claim is that there have been iPad eBooks created using Corona which have made the top charts on the app store (See: http://blog.anscamobile.com/2010/11/rabbit-and-turtle-race-to-1-in-app-store-ebooks/ for a quick example).
Also, Chronicle Books (San Francisco based book publisher) has used Corona SDK to produce an eBook for the Nook platform:
http://www.barnesandnoble.com/w/animal-show-chronicle-books/1100618669
And several others I can't think of off the top of my head.
The reason why Corona is great is because books are about getting images, text, and interactivity on the screen, and with Corona, you can do each one of those things in just a few lines of code or less!
Also, with the full-power of OpenGL, you have near limitless possibilities when it comes to adding as much--or as little--interactivity to your book as you want. With Corona, you really do get to focus on the logic behind your book app, rather than all the technical details which are handled transparently for you in the background.

We're in process of developing a desktop application which needs to record user's screen once he clicks a button. I read a tutorial about Adobe AIR, which says it is easy to do with AIR: http://www.adobe.com/devnet/air/flex/articles/air_screenrecording.html
But our preference is Titanium as we've explored it a little bit. So I want to know is that even possible? If yes, how can we get started with?
There's also an interesting solution which uses Java applet for recording, as demonstrated here: http://www.screencast-o-matic.com/create?step=info&sid=default&itype=choose
But again, we're not sure about JAVA and would like to know how can it be done? or if its even possible to run a JAVA applet in Titanium?
When you say "record screen", I'm assuming you mean video. Correct?
The only way to do this in Titanium Desktop right now is to take a bunch of screenshots and string them together (encoding would probably need to be done server-side).
Depending on how long your videos need to be, this probably won't work for you. I'm also not confident in how quickly you could capture screenshots, and if it would have a high enough frame rate to be usable.
Past that, a module could be developed for Desktop to support some native APIs to record video. That's not something I see on the horizon, though.
I hope this helps, albiet a rather dismal answer. -Dawson
My need is that when Playing a video in movie player when I tap record button the video plays and at a time the video shud also record.Can any one suggest how to do this.
Anyone's help will be deeply appreciated.
thanks to all,
Monish.
It seems unlikely that this would ever be possible. If it were, it would open a huge copyright hole. For instance, you could buy a movie on iTunes, then have your app 'record' it while it's playing in Movie Player and then send the movie elsewhere. This will almost certainly not be possible using the released SDK API, and the task would likely be quite non-trivial even in a jailbroken content. Even if you figured something out, I can't see any way that an app with this functionality would be seen as being in compliance with the App Store guidelines. (Sections 8.5, 9.1, and 22.4 all look relevant here.)
