I'm a little bit confused now. There is a weather and stock widget on the iPhone. Is it possible to create such a widget yourself? I don't want to talk about new features in iOS 5 here. I only want to know it in general (iOS < 5).
Here I found the introduction guide with the help of Dashcode.
Wikipedia also states that this is not possible. I always thought it would be.
So are there only web apps and native apps possible?
PS: What is a widget exactly? A combination of native app and HTML, CSS, Javascript? Only HTML, CSS, Javascript? A cocoa application?
No, iOS does not currently allow the creation of widgets. The weather and stock widgets you're talking about were created by Apple. There are no APIs to write your own.
As of iOS8, its possible. 3rd party apps will be able to create widgets for the notification center.

This isn't a Guide for iOS Widgets, it's Guide for Mac Dashboard Widgets.
You can't
create iOS Widgets
change how the iOS Notifications Appear
With Dashcode you can create Web Applications for both iOS and Mac. It's a combination of HTML, CSS and JavaScript. Those Web Applications are only available on the Web (e.g. Safari). If you wan't to create a native App you have two possibilities:
Create a real native Application in ObjC
Create a Web Application (e.g. with Dashcode) and load it into a UIWebView, this requires also ObjC.
Advantages
Web-only Application (Browser-App)
You don't need a Apple Developer Account
Easy to port to Mac and other Smartphones
Unreal-native Application (Browser-App in a native App)
Easy to port to other Smartphones
It feels like a real native app
Your app is on the App Store
Native Application (Real iOS-App)
You have full access to the iPhone Frameworks (e.g. Contacts.app)
Your app is on the App Store
Disadvantages
Web-only Application (Browser-App)
The user needs to know your URL
You're not in the App Store
Unreal-native Application (Browser-App in a native App)
You need to pay 99$/year for an Apple Developer Account
It could feel like it's not a native app
You have not the full access to the iPhone Frameworks except you use something like PhoneGap or ObjC
Native Application (Real iOS-App)
You need to pay 99$/year for an Apple Developer Account
You can't port your app easy to other Smartphone
You need to learn ObjC
No, currently thats not possible. But you can, and should, file a feature request at bugreport.apple.com so that this issue gets some attention.
There is no reason you can't create a widget like component using javascript and display it in a uiwebview. This works equally well in android and iOS
A few years ago when I was involved with java server pages development I put together a tutorial of using dashcode to wrap java or javascript components.

I am new to IOS development (currently, I'm developing websites in ASP.NET) and I found out that one can create an IOS app using just html 5 and javascript.
Well that is great news for me since I don't have the time to learn Obj-C and xCode way of writing apps.
I have heard some opposing statements, though, on whether I will be able to submit my app into the app store.
Will I be able to submit such app in the app store?
If not, is there a way to 'wrap it up' somehow, so it could be submitted?
Thanks!
No, only native app will be listed in the App store. To submit apps to the appstore you will always need a paid Apple Developers account.
Native in this case meaning real apps that can be installed.
You can build an app in HTML and Javascript in tools like Phonegap and Titanium. These tools will create a native app which loads the local HTML and try to make it feel like a native app.
You will need to use a wrapper, like AppMobi (where I work). This lets you write your app in html, javascript and CSS only.
You need to wrap your application in a UIWebView container. As far as I know, there's no way to package an HTML5 only app for the App Store. I have four apps in there that are HTML5/Javascript apps, wrapped in a UIWebView. There are also third-party frameworks available for this.
i have an existing iPhone and android application. my goal is to make some component in thsese apps reusable. so i am identifying components which are not using device capabilities and then will design these components from HTML pages so that the same code will be used in both apps.
one more requirement is that whatever web service is being used , that will be called from objective C or Java code and response will be consumed in my Html page.
Please give me your ideas as how can i achieve it?
what all tools should i use to make these pages?
are there any challenges, that we need to face at any stage in development?
I have no idea of web site development and html technologies, that's why i am looking for a help here.
Thanks
Rather than have bits of native and bits of HTML you would be better to develop the entire thing in Phonegap. Phonegap is developed in HTML and JS and then compiled into a native app utilising the OS's web view. This means that you will have the exact same code across devices and will allow for a more consistent UI.
Phonegap allows for native device functions to be used such as geolocation, accelerometer, audio, video, notifications, storage and more.
use Jquery Mobile to develop user interface and to package it as a offline app use phonegap.com
Hope it Helps !!!
EDIT:
See my answer
I saw some interesting frameworks to build applications for mobile platforms like Android and iPhone with HTML and Javascript so you can use your current web-development skills without learning a new platform language. That's very interesting because you can write just ONE application for many platforms. Very easy to maintain.
But, you cannot sell it in the App stores, so I’m wondering if it is possible to use an embedded webbrowser in the application that loads an external/included html file.
I have seen that it is possible to create Android and iPhone apps with flash, that's is easy, so i want to create a simple 'host' application that only loads content and I can use it over and over again to distribute a new app.
So the question is, is it possible to create a simple app with flash that embeds a webbrowser to load a html file?
When it is possible, next question is, it possible to communicate with the embedded webbrowser? Also a question is, will Apple allow such application in it app store?
I hope my question is understandable.
In a very strict sense, yes, you can make an app that is just a simple WebView wrapper pointing to your web-hosted app.
This is usually frowned upon though in the android market community, and i'm fairly positive such an app won't make it through Apple's closed-doors decision committee.
On the iPhone, if your app only consist of a UIWebView it is very likely that you app is going to be rejected. What you could do is ask your users to bookmark your webapp adding an icon to the home screen. Think Basecamp for iPhone.
After all this time i got the answer.
Phonegap uses a WebView to display the HTML content. It is a compiled native App with embedded WebView.
Apple accepts phonegap generated applications but it still not sure if it made it to the AppStore, it depends on what you doing with it. I think simple apps will made it. See also: http://www.phonegap.com/faq
EDIT/UPDATE:
I tried allot of tools/solutions to create crossplatform apps but all of these seem to do the same thing: It's a executable for the specific platform with an embedded browser. None of them compiles HTML to native code.
Flash (Builder) is something different, it requires AIR (can be compiled into the executable). When you using a WebView (only) with Flash, it is overkill because in fact you do not need AIR to display the HTML in a WebView. I think it is better to use phonegap to 'compile' the executable.
If I make a iPhone app, like a grade manager. What technologies are necessary to make it into a web app.
This includes reading the data from iPhone app in the web app portal (not necessarily editing from web app as of now).
I think I need to transition from using plists to using MYSQL?
Probably you need to this:
http://www.phonegap.com/
it's an Open Source Mobile Framework That Supports iOS and other platforms.
Hope it will give you a guide.
The best approach would probably be to write a web app that can communicate with the iPhone app, not "converting" the iPhone app to run on the web.
I was looking into PhoneGap and Titanium framework, and I did not clearly understand how to they work, let's suppose I have already developed an app for android or iphone, can I run this app on another mobile with a different OS with PhoneGap or Titanium help?
Or I have to develop again my app with PhoneGap/Titanium framwork?
In this case I have full support at all the features like thread, JSON or XML parsing and so on?
Thank you
PhoneGap basically takes a client-side web app (HTML, CSS, JavaScript) and wraps the whole thing in a native device's web view control. You can hook to some of the device's native functions, but as you can guess, it's pretty limited compared to native development. But easy, and brings in a whole range of skills that a lot of people already have. That's really the appeal of PhoneGap.
Titanium is also html/javascript oriented, but it actually claims to compile to native code. Their sample "kitchen sink" app demos quite a lot of the native APIs, at least for the iPhone. I doubt you'd be able to deal directly with threading, but JSON for sure, and I'd think XML as well.
Titanium has full support for JSON or XML parsing.
You can see Titanium examples - Kitchen Sink - for more details.
The idea behind phone gap is that you can take a browser based client app that is written in html/css/javascript and use phonegap to gain access to some native mobile hardware like contacts, gps, accelerometer, etc. Phonegap allows you also to build this web app for different mobile devices all using the same web app code.
To answer the first part of your question, no, you would not be able to take a developed app and use PhoneGap or Titanium to run the app on another device.You would have to write the app in either the PhoneGap or Titanium Framework and then build the application to the devices you want to support through the tools that each give you.
For example, you would write your code in JavaScript(Titanium) or HTML/CSS/JavaScript(PhoneGap), then use the app's build tool to create the file that would be released onto the phone.
