Introduction to programming in ios with swift

-
Started with aim to write blogs with three languages now covering large area over languages introducing ios programming with swift language as we know for application in mac we have swift language so we will talk about swift language later on.
 
 
Firstly to write a program we need an editor in any language So as far as swift language is concerned for programing in ios we have an editor known as XCode , This is  a development tool for applications.
 
XCode contains Sdk , Emulator  so its a complete package not just as in Android we need to install Gennymotion.
 
In android we have a java file and an xml file Known as androidmanifest.xml which is configuration file here per screen we have ..
 
  • Storyboard (for U.I. design)
  • Swift (for business logic)
By opening a project we can see mainly 3 window
  • project explorer
  • editor pane
  • utility window
Same as in android here we have to give a project name for example we give FirstApp.
 
So that becomes our root folder the sub folders here will be
  • AppDelegate (contains events for whole Application)
  • ViewController.swift (For business Logic)
  •  main. Storyboard (U.i design)
  • images.xcassets (contains images for whole project)
At last we have launcherScreen.xib/.storyboard that was launched beyond xcode 6 as earlier for launcher screen for different model we have to craft or modify the images according our suitability but now we have a facility that it dynamically takes the size of the image to the size of screen.
 
Here the configuration file is Infoplist(plist--->property list) 
 
 
IN next post we will study the swift language till that keep reading and explore your concepts .

State space search / blocks world problem by heuristic approach /TIC TAC TOE

-
A lot of AI is about SEARCH. The "state space" is the set of states of the problem we can get to by applying operators to a state of the problem to get a new state. A  state  contains  all of the information necessary to predict the effects of an action and to determine if it is a goal state. State-space searching assumes that the agent has perfect knowledge of the state space and can observe what state it is in (i.e., there is full observability); the agent has a set of actions that have known deterministic effects;some states are goal states, the agent wants to reach one of these goal states, and the agent can recognize a goal state. a solution is a sequence of actions that will get the agent from its current state to a goal state. Define the Problem as State Space Search Consider the problem of “Playing Chess” . to build a program that could play chess, we have to specify the starting position of the chess board, the rules that define legal moves. And the

Navigation in Vaadin.

-
Plain Vaadin applications do not have normal web page navigation as they usually run on a single page, as all Ajax applications do. Quite commonly, however, applications have different views between which the user should be able to navigate. The  Navigator  in Vaadin can be used for most cases of navigation. Views managed by the navigator automatically get a distinct URI fragment, which can be used to be able to bookmark the views and their states and to go back and forward in the browser history. The  Navigator  class manages a collection of  views  that implement the  View  interface. SO the class in which you are defining Navigation must implement with a  View  interface. addView() i s the method by which you can register Your View . You can add your view at any point ,Your View must have   name identifier and be added to a  View . Once registered, you can navigate to them with  navigateTo() . Navigator  manages navigation in a component container, which can be
