title: static Library in Xcode 4
body: <p>I am too much of this Static Libary thing in Xcode 4.X</p>
  
  <p>Following are the steps that I usually do..</p>
  
  <p>1)For making a static libary , I open Xcode , new , static libary , and then by adding some classes in the project .. then build phases ->copy headers -> add all headers here one by one,and then i build up the project 
  when run on ios simulator -> static libary does not created ..(red color)
  when run on ios device - > static library gets created..</p>
  
  <p>2) for using the library..
  I make a new Project , then i "add files to project" and also "copy if needed" the following 2 files..
  .a file (i.e.static library)
  folder consisting the headers of library files</p>
  
  <p>Now when I try to import a header file in my project , there is no "suggestion" appear ...but still i write and it does not give an error "header file not  found"...</p>
  
  <p>but when I run the project it gives the error like:</p>
  
  <blockquote>
