I am trying to develop an application for file sync on the cloud.I came across the DropboxSDK which is fairly simple.I've kept this as an option for my app.I found another one called Box .Net, but its a bit complicated.Can anyone let me know what all api's are there similar to DropboxSDK which can provide the same functionality.Thanks!!
Did you hear about iCloud?
There's also Cloud App (might not be functionally equivalent – it's more for sharing files AFAIK).
With iCloud becoming built-in in OS X and iOS soon, however, it's likely to become the standard. Don't know how well it will work for legacy users, who don't upgrade to 10.7, though.

I have been learning objective C for about 3 weeks and I achived basic concepts but now I am trying to get hands on experience and since I dont own a mac Im trying realy hard with virtualization and have big problems (i succeeded only with snow leopard 10.5 which is version to old for xcode 3.2) nevermind, Im starting to wonder if other solution for iPhone development like phonegap, mobieOne are realy that bad? I know the native development is the best, but if you bulding application that use some menus and displays data from database is there sensible difference?
Consider trying RubyMotion. If you know Ruby of course. http://www.rubymotion.com/
Here's a macbook on eBay for 300$. Im sure its not the greatest computer in the world, but you should absolutely be using objective c for an iphone app.

Any time you lose in learning the language (which I agree was a bit of a long and frustrating process) you will gain back by using all of apple's documentation and the copious online tutorials. All the resources out there assume that you use Objective C.
I know its a slow process but invest in your future and do it the right way.
check these two:
Sencha Touch
Mono Touch
If you really wanna do serious iOS(could also be Mac OS X) development, you definitely wanna get a mac. You can use hackintosh on your pc, or download iso image of a modified Mac os x and run it on Virtual Machine (e.g: VMWare). However all you can find would be probably still limited. Last time when I looked on internet, I only found image file for snow leopard but soon Apple going to release mountain lion(which means the hacked Mac OS could be two generations behind).
You can use third party tools other than xcode to develop iOS apps. There are tons of them by using different languages such like C#, java, JavaScript,HTML5, but when they get complied and translated into a native iOS app, you will still need to have xcode running on a Mac.
Again, two things. First, I think you'd better have a mac, and if you don't, you need to find a way to get around it and you might not be able to catch the latest technologies(and that changes quite often in iOS!). Second, if you prefer to develop through a third party tool, it's depends on what languages you are most comfortable with. For C#, I recommend MonoTouch, and for JavaScript, I recommend SenchaTouch. You can find a lot of others.
just checking if its possible to sync iOS devices AND a web app through iCloud. Currently we've got an iOS app built, are looking at using iCloud for synching between all the devices and also want a web app component. iCloud would be great to use as the module to sync everything together.
Anyone know if it's possible ?
I have a similar requirement and have wondered about this too.
Unfortunately iCloud data doesn't seem to be accessible to a Web app. And if you found a hack around it, it would still be an unreliable solution as Apple could always make changes down the road that break your Web component, intentionally or not.
Edit: With CloudKit this is no longer true. It comes with a Javascript API for the explicit purpose of providing a web version of your app.
Sorry if I'm misunderstanding the question, but I was looking to add iCloud support to my web app recently and came across the official iCloud JS API. The promo text reads:
Keep your apps connected and up to date across iOS, OS X, and now on the web with CloudKit JS.
[emphasis added]
https://developer.apple.com/icloud/
It is really hard to determine what you mean.... If you are asking if you can implement iCloud in a web app, then I believe that the answer is 'no', since there is only an API for Objective-C for iCloud.
However, you might be able to embed your JS code inside of a native wrapper and write some native code for working with iCloud. However, that may or may not be an option depending on your particular situation.
Edited for spelling.
You could possibly do this, but only if
You where running your own server
The server was running on the iOS platform
You where able to create software in Objective-C for that server
You could then potentially write a server application, that could be used to connect to the iCloud API, then return the calls back to the end user as Json messages that could be consumed, perhaps by some html interface.
I am currently building an iOS application with flash CS5 and I would need some help with a couple of the features:
Is it possible to add in-app purchases? If yes, how does that work?
Is it possible to add iAd advertising to the app? If so, how? If not, is there any good alternative that works with flash?
How can I save data from within the app so it will be there eaten if the user restarts the app and even the device (like for a headboard and such)?
Any help is highly appreciated!!! :D
If it were a few months ago. Then answer would be an unequivocal no. However, presently, the answer is "perhaps" (or if you are an optimist, "probably"). With the release of Air 3.0, it now supports Native Extensions. These extensions are native code that have a wrapper API around them so that they can be compiled in with and called from an Air application.
In fact, I decided to look around real quick while researching for this answer and found a repo where it looks like somebody has implemented in-app purchases via a ANE. But I haven't tested this extension personally, but it may be a good starting point to see how it is implemented.
The reason you wont find too much information about ANE's yet is because they were only recently supported in the Air 3.0 update that happened last month. They are currently unsupported in Flash CS5 (or 5.5) or Flash Builder 4.5. They are supported in Flash Builder 4.6, which is currently in a closed beta. But you might be able to sneak in still, and it should be released soon.
The biggest "drawback" is that these extensions need to be developed in the native format for the device you are targeting. So that means, if you want to make an iOS extension, then you are writing it in Objective-C and xcode on a mac.
Pretty much the same answer as before. It should be possible with a ANE. But I haven't found any examples of anybody doing it yet.
It is very simple to save data/state to the device. You'll want to look into the SharedObject.getLocal() method if you want to the LSO. Or you can just use low-level File writing. Check out File.applicationStorageDirectory. For sensitive information that should be encrypted into into the EncryptedLocalStore class, which I believe is supported on iOS but not on Android.
All of these should provide a good way for you to persist data between application sessions.
With AIR 3 you can now use native extensions to call into the native platform code to achieve the functionality not provided by AIR Actionscript APIs. To answer your questions.
in app purchase. I have a sample at http://code.google.com/p/in-app-purchase-air-ios
iAd. I have a sample at http://code.google.com/p/iad-air-ios/
As others have already answered use local shared objects.
Is there any MacOS virtual machine that can run on PC?
Is there any source to get it?
What is the best way to develop apps for iphone?
Yes all the developer tools are OSX only.
There are lots of iPhone development books out there go check out amazon and find one with some good reviews and that will get you started.
You might not, in the strictest terms, have to get a Mac to develop for iPhone; but it will be extremely helpful. Apple is relatively talented at squashing efforts directed towards Hackintoshes and virtual machines running OS X.
The shortest answer that will give you the least hassle is: Yes you need a Mac.
But, as far as I know there are a few possibilites, that try to reimplement some Cocoa Frameworks (however they might be Mac OS X only and not iPhone): GNUStep is an example.
But I don't think you get something aquivalent to Xcode (the IDE for iPhone development) this way.
And I think there are some OSX86 Virtual Machines (however these seem to be against Apple's EULA and thus seem to be clearly illegal so I won't point you anywhere to get them).
So to conclude - if you want to develop for iPhone: getting a Mac is the easiest way, even though not cheap.
Hope this helps.
The short answer is - yes.
One possibility for learning some of what you need to know before getting a Mac is GNUstep.
However, GNUstep is mainly useful for learning Objective C, especially since it provides many of the classes that the Cocoa toolkit for iPhone does. This can be run on Windows.
It doesn't, however, support some of the key 2.0 language features that are used 'all the time' in any sample code.
What it will allow you to do is design a UI using their UI designer GORM, and use a near-identical message-based system for implementing a UI, and you could theoretically write Objective C classes in GNUstep and then use them on iPhone.
However, to compile an app for iPhone you basically need to have a Mac, because then you can get the key for signing an app, etc. Since you need to get a Mac at some point, there's really little point in going the much harder route of using GNUstep first and learning a more limited implementation, unless you really need to get started before funds are available.
Despite the new SDK terms that can other programming languages, if you're really wanting to start without a Mac, I'd probably be tempted to look at something like Unity, or perhaps even Appcelerator Titanium, and figuring out all the non-platform-specific logic first on whatever platform (Unity has a free version that can be run on Windows, for example).
I'm not that big a fan of xcode, but is is far and a way the best IDE for Objective C development simply because there's almost nothing else out there.
There are, as always, other options. If you do a web app type project, you can implement the website and test a lot of it in a browser. Furthermore, since Android and iPhone browsers are both WebKit based, you can use the free Android SDK to see what pages look like on a comparable mobile device. And since you can use C and C++ classes as well as Objective C (N.B. not for the GUI, since that needs the Objective C extensions for messaging between objects), another option for making a start without a Mac would be to use Eclipse, QT Creator or some other C/C++ IDE to implement non-GUI classes, so long as you make sure you don't use platform-specific libraries.
But the end of the long answer is still that whatever you do, to compile a proper iPhone app you'll be using xcode and associated tools to finally build it and sign it, and so you need a Mac in the end. If you want to create something targetting the iPhone and won't have access to a Mac, then perhaps you're best off looking at creating an iPhone-adapted website using iui or a similar toolkit to give the site a suitable look and feel.
I know there is a requirement in their EULA, but I heard about people getting their apps developed on Windows into the app store.
How can Apple find out, or do they even know?
They don't, so if you get a native compiler and toolset up and running on Windows, more power to you.
But realize that:
You will not be able to use a language that compiles to bytecode (that's Java, C# and the .Net languages, Perl/Python/Ruby, etc.). Apple will most likely not allow any sort of interpreter through the App Store.
Chances are your tools will not contain an Interface Builder equivalent or an iPhone Simulator equivalent. You're going to be writing a lot of code and spending a lot more time testing.
You won't have local documentation. You'll either have to use Apple's website or rely on third-party documentation which may mix App Store-allowed and -forbidden methods without indicating which are which.
You won't have Xcode's editor, which is highly specialized for Objective-C. You'll have to type a lot more.
You won't be able to get help as easily since you're not using the same tools as others.
You will never know when a bug is in your code, your tools, or your platform. People using the official SDK can file bug reports on the tools just as easily as the platform.
Your tech support incidents are worthless, because you're violating your contracts.
If Apple ever does find out, you're likely to be kicked out of the App Store and all your work will be for nothing. Unless you're an idiot, this thought will worry you.
If you're a hobbyist, these may be acceptable to avoid paying $400 for a used Mac mini, but if you're not a hobbyist...this is no way to run a business. Pick up a used Mac and think of all the money you're not spending on a factory, a store, offices, inventory, or employees during your setup time.
There is no sdk available for Windows. XCode only works on Mac OSX, how would one compile, test, and run the app if not on Mac OS X?
I dont think they know. There's no official SDK for the PPC architecture, but some simple installer hacking yields a working binary for my Powerbook. Similarly, if you get your code working on Windows, more power to you...
