The Android platform has a RatingBar widget. I believe there is a similar field for BlackBerry because BlackBerry AppWorld uses a rating bar. What field are they are using for that?
I was browsing another question on StackOverflow and found a reference to a BlackBerry knowledge base article that includes sample code for a RatingField.
The corollary to an Android Widget on the BlackBerry is a Field. The BlackBerry Widget SDK is meant for doing web development specifically for BlackBerry devices. I've edited your question to reflect this.
The important aspect to know about BlackBerry development is that the operating system is not open-source. RIM has chosen to make some APIs available for app developers, but they have not opened up the entire platform. RIM is able to access the entire operating system when they write an app themselves - such as the Facebook or Twitter apps, but if you are writing an app as a third-party developer, you are limited to what has been exposed in their developer JDE.
AppWorld may well use a built-in field that does the rating stars, but, if it exists, that field is not available for third-party developers.
It is actually pretty common in the BlackBerry culture to write your own Field objects. There is a ButtonField in the JDE, for example. It works well if you want a button with text. But if you want to make a button that contains only an image, there is no built-in ImageButtonField to use, and you cannot set an image on a plain ButtonField. You have to write your own button field to handle this.

I'm currently working on an app where I need to displa charts like in the added picture. I already know about ios-charts framework, etc.
But I really like the charts from iOS 9 health app landscape mode. It's showing current value when touching:
Now I'm wondering if this kind of chart is available for developers from Apple in iOS 9, because I already saw it in some other 3rd party apps (e.g. Idealo app for iPad (Germany))
Thanks in advance!
No, there is no native Chart library in iOS. There are however, plenty of libraries available. Unfortunately, you will need to dig through them to find the one closest to what you've seen.
Of course, you could also reach out to the developers of the apps you like and ask them directly. Most developers like to share information like that.
I have developed an 'App for Office' (for Word) that runs as a task-pane app. When I open a Word Document, I can add my app and let it run on the task-pane.
How can I run my app when I am on my iPhone/iPad and using the iOS version of Microsoft Word? I wasn't able to find where I can add my app into the document.
I am aware this is more of a support question for Microsoft, but Stackoverflow seems to be the best place for now (I couldn't find any relevant StackExchange site).
Store add-ins are definitely supported on IOS in general, but not all add-ins. The developer has to tick a box and provide evidence that the add-in has been tested on IOS for it to be available to users, so the IOS versions of Office will have less add-ins available.
That said, you should be able to see the ones that are available via the Insert menu. Look for Store or My Add-ins under the Insert menu.
I recently found a site that allowed me to bookmark the site and then use it just like an app. There was no url bar, it was indistinguishable from an app you would download on App Store. Is this a new upgrade or technology ?
This is not new technology, I don't remember how long it's been out, but I'm pretty sure at least since iOS 3. It's called a webclip. You can do quite a bit with a webclip but are still limited to functionality provided by JavaScript, so no accessing the flashlight and certain hardware features (although many are being included in the device JS object). Though it is certainly much easier to implement basic app functionality!
+1 to SnoApps and here's a bit more detail about this older detail.
You can specify a webpage to appear like a regular app icon on the iPhone "home" screen (where all the apps appear).
There's more information here under the "Configuring Web Application" section of this Apple Safari Web Content Guide.
Is it possible to write new accessibility services for iOS? It's easy to find info about how to make write apps so they are accessible, but I want to write a new service that has capabilities like a screen reader would have, and that works with existing apps.
From what I can tell, it's possible on Android with the Accessibility Service, on Windows with UI Automation, and OS X with Accessibility Framework. But I can't figure out if iOS has a similar capability.
The short answer is no. The long answer is what you are asking to do is a system utility and on the iOS platform developers are only allowed to write applications that are for the most part sandboxed I.E. they can only interact with themselves or apps by the same developer. They are forbidden from accessing data from other apps on the device. Developers also have no access to what so ever to system files that control things like font size and text to speech. Apple exercises tight control over their OS to maintain a stable platform.
Hope this answered your question!
You can't define a new system-wide service, but you can customize the existing services pretty heavily in your apps.
You can disable the default accessibility controls for a view:
view.accessibilityTraits = UIAccessibilityTraitAllowsDirectInteraction;
view.isAccessibilityElement = YES;
You can use the informal accessibility protocol to define your own VO cursor frames, and post UIAccessibilityLayoutChangedNotification notifications to make VoiceOver speak.
I'm building an app, i just thinking like adding a feature so, that the user can be given guideline about how to use the app and various control in it.
The feature that came to my mind is , when unboxing android mobile you will see an overlay describing the menu, app .
so, is there any similar feature that iOS or any third party library provides. if so, will app store testing team will approve it.
