I want to create a horizontally arranged context menu. This means when my application is running and I press the menu button that my customized horizontal options will show. How do I do this on BlackBerry?
You can override onMenu method in the Screen class and show your custom PopupScreen menu.
This can be accomplished as #Eugen Martynov has mentioned. Though your idea might sound novel, it doesn't go with the UI guidelines of a Blackberry application. Regular Blackberry users might not appreciate the new UI you are proposing. And moreover, there is a possibility of your app being rejected when you submit for certification to host in Blackberry App World.
Check the guide lines here
Point no 3.4 mentions that the user must be able to use "Switch Application" feature from within the application. Though you might design the app to adhere, there is a possibility of rejection for non-standard implementation.

I have a button in my app that brings up the system app settings UI. Instructions are given around the button.
I want to provide further instructions to the user via a toast message after the settings page shows up so they know exactly what to do. It's not a super intuitive setting, related to notification style, and such instructions would be a lot clearer when the user is actually on the settings page.
In Android, this is easily done via toast.makeText().show(). The resulting toast would have no problem going on top of the system settings UI.
In iOS though, I've looked up several guides, mostly using the UIView animation. The problem is, the resulting toast window seems to only work inside the app itself. It cannot go on top of the system settings UI.
Is what I want to achieve technically possible in iOS?
No. You are sandboxed; Settings is a different app and you cannot impose anything on to its interface.
If one writes a custom app is it possible to be able to add a shortcut to the iOS lock screen? Or is that reserved for Apple sanctioned apps?
Currently, one can go into settings and add, say, the voice memo app to the lock screen control center. Of course, these shortcuts are available when you've signed in as well (by getting to the control center).
I like to use React Native and Expo, but my question is more general than that (but let me know if you know of any Expo tricks for this).
Currently it is cumbersome for the user to repeatedly scroll and take a screenshot if they want to capture more than what can fit on the screen at a time.
I would like to implement functionality such that at the request of a user (e.g. via tapping a special button on a custom keyboard), screenshots of the entire scrollable area of the currently opened app are automatically taken and stitched together.
Is this possible? And if so, how?
To clarify, the application containing the scrollable area is a third party application over which I have no control, e.g. iMessage or Facebook.
Edit: I am aware of answers like this one and this one that are about taking screenshots within an app that I control. As far as I can tell, these are not applicable in my situation. Please correct me if I am wrong about this.
This is not possible. Each app is contained in a protected sandbox that no other apps have access to.
You could make a custom keyboard, but you still wouldn't have access to any of the views in the app that you don't control.
How do I create a tab bar like WhatsApp on BlackBerry in my BlackBerry app? I want that feature in BlackBerry OS 7.0. I have used managers -- HorizontalFieldManager and VerticalFieldManager -- to achieve it. But it doesn't look as attractive as WhatsApp. Can FieldTabController help me do this?
It's not going to look attractive if you are just making tweaks to the code, and then seeing what that looks like. You need to start with a design you find attractive. Once you have that goal put together as an image, you start writing code to make the UI look like the design image.
The WhatsApp tab bar is not a straightforward combination of built-in UI managers from RIM. It has a fair amount of customization - each tab has three visual states, and there is a tooltip that follows the focus, as well as a context tab on the right that changes depending on the currently selected main tab. This means there are several interacting UI components here, not just a single magic manager.
Essentially, you will probably want to start building your own custom Field objects.
Basically, subclass the Field class (or one of the other subclasses), and learn to love the paint(..) method and the Graphics API.
I am running an iOS native app on iOS Simulator and would like to inspect the elements on the app to get the ID.
Does anyone knows how this can be done?
Note: Please, this question is for iOS native App not Web based app!
Thanks
It sounds like you may be looking for something like Firebug or the Chrome Inspector for your native app? I'm not sure what you mean by "ID". Interface elements in iOS don't really have IDs the same way DOM elements have IDs.
You should check out the Spark Inspector (http://www.sparkinspector.com/), which allows you to see the views of your app and modify them at runtime - it may help you see what you're looking for. Full disclosure: I am the author of the app ;-)
There is a new app, called Reveal, that does an incredible job.
Not only you can check view's properties, you can also view all the app in a "exploded" 3D view, change the sizes and properties.
Specially for iOS 7, where the view controller starts from the beginning of the screen (and not below the navigation bar), it can be really useful.
You can download the trial at http://revealapp.com and decide which license you should get.
There are two Best ways for this -
Use Accessibility Inspector which is Apples's inbuilt tool so you don't need any other support .
As you will be using Xcode mostly for you code part, there is an option to play UI recording which capture all the actions and elements that you interact with on native app.
You need to inspect the App's Bundle.

Appium has an inspector for ios applications.
