Is there a way to display the Openlayers map just in English? It currently displays by default in all languages depending on the user's locale.

I am building an iOS map with local search functionality similar to Yelp.
The user will see a local map generated from Google Maps SDK from iOS, and local points of interest returned by the search, will be displayed on the map as custom markers. Simultaneously, the user can also see these same local search results in a list form on another screen.
My issue is as follows: to optimize loading time, I would like the app to load only the search results within the area displayed by the map, given the coordinates of the center of the map, and the zoom level. This would be more efficient than loading, say, all search results within a 30 km radius, most of which may not be visible on the map. Is there a simple way to know exactly what are the coordinates of the area displayed by the map on the user's phone (bottom left corner, top right corner)?
I have seen other posts online, explaining how the coordinates of the area can be calculated using zoom level, latitude, and screen resolution. However I am wondering if there is a simpler way commonly used by other apps that display local points of interest.
Thank you!
I'm developing a BlackBerry 10 mobile application using the Momentics IDE (native SDK).
I want to display a map using the mapview qml element which seems that it belongs to the blackberry team (it's not a google map). [ Blackberry 10 mapview ]
All I want is to configure the zoom level like google do, but it looks like the blackberry map doesn't have any attribute which can guarantee that except the "altitude" element which can assign some sort of zoom .
Any one can help on this ?
The altitude property is indeed the one you use for zooming. The paradigm is "how much area is viewable from a given altitude?"
To zoom in and zoom out from the map uses the altitude property.
To create zoom in/out animation you can use a simple javascript function that manages the animation. (For example implementing Elastic or Circular animation. See the Blackberry Stock Curves documentation for more details).
Instead, if you want determinate the viewable area from a given altitude you should work with the map scale

I am using the MapBox iOS SDK for my project. Now I want to show shaded area in the Map for a particular area like any country, any continents etc. So how can I implement this feature.
Your suggestions and response will be helpful.
You can either do this client-side with something like RMShape or server-side by either shading things on the Mapbox.com online editor or making a custom map to upload with TileMill. The Mapbox site has lots of documentation on doing these things.
I am currently using KML files that are generated from google maps. The KML's that have complex polygones have a Legend as well. I would like to display the Legend. I'm wondering if there is a way to do this using the current IOS Map api's
Ideally I would like to be able to search tweets by country however search/tweets endpoint only supports geocode in the format of "latitude,longitude,radius" unlike the streaming endpoint which you can set a bounding box.
How do you best search by country?
As a simple solution I have thought about calculating the centre of the bounding box along with the smallest radius to remain in the bounding box.
