Hi there! We are a group of iPhone / Android developers who have developed a suite of web services to assist us and other developers in building great apps.

After numerous projects we have become tired of having to set up the server scripts to do all the same things for different clients. Most of the server functionality

is typical: 1) storing location data for Google Maps; 2) storing users’ high scores / ranks; 3) sending Push Notifications; 4) storing files / XML; etc.

We couldn’t use the existent solutions because in some cases they didn’t provide the required functionality and in most cases they require your users to be exposed to some social network of theirs, while our clients just want a simple functionality without users knowing of any services behind that.

So we have launched what we call Mob1serv, a universal server solution for the typical needs of iPhone / Android apps. It consists of modules which deal with most common tasks:

* High Scores – a powerful online high scores table
* PushNote – a module allowing to send immediate or delayed Push Notifications (you can build instant messengers or alarm clocks, anything with this)
* GeoPos – stores locations of Google Map objects, their statuses and ‘last seen online’ time
* OAuth contracter – allows you to implement transparent authentication and integration with Facebook, Twitter, Google etc
* More modules to come!

Many people could not find this solution! It’s really very simple solution and it does not contain any private methods and functions. It’s based on the drawRect method and the simple manipulation with the title. If the title is specified, then the text of title displays, but if not, then displays the image.
