How can I create static library and can add just .a file on any project in ios

if you want create static lib mean refer the link http://jaym2503.blogspot.in/2013/01/how-to-make-universal-static-library.html

Step 1 : Create a New Project, Named it "Logger"

Step 2 : Create Classes

You can create as many classes you wants, In our tutorial we will create one class named "Logger". So, now two files should be in our resource.1. Logger.h2. Logger.m

Step 3 : Put some useful code into Classes

Step 4 : Create New Target

Create New Target from File Menu.

New TargetSelect Cocoa Touch Static Library

Step 5 : Add files to Compile Resource

Select "Logger" Target of Static LibraryGo to Build PhasesIn Complied Sources section, Add all the .m and .mm files.In Copy Files section, Add all the .h files and resource files.

Build Phases

Step 6 : Compile Project with Static Library Target

Compile Project for iOS DeviceCompile Project for SimulatorYou can find two different .a files generated in build folders.

Find .a file

Step 7: Make Static Library Universal

You can find two different library now, one is for simulator and one is for iOS devices.

Create a New Folder and name it LoggerMerge.Copy libLogger.a file of Debug-iphoneos folder to "LoggerMerge" rename it to libLogger_device.aCopy libLogger.a file of Debug-iphonesimulator folder to "LoggerMerge" rename it to libLogger_simulator.aOpen LoggerMerge folder with TerminalFire below commandlipo -create "libLogger_simulator.a" "libLogger_device.a" -output "libLogger.a"

Now, you can find libLogger.a in LoggerMerge folder, this is Universal static library file.Now, Just one thing you need is headers, See above screenshot there is folder called include in both build folder. Just copy header file from this folder.

Step 8 : Test Static Library

Create New Project, name it TestLoggerImport libLogger.a and header filesImport header file "Logger.h" anywhere you want to useNow, Use this Logger class as default practice.In our case, [Logger log:@"Test String"];Run Project in Simulator and Device bothThat's it!! You have your own static Library!!

Step 1: Starting a New Static Library Project

Open XCode and start a new project. Under iOS, select Library and “Cocoa Touch Static Library” say it as "staticlibrary". This will create a nice new project for us that builds a .a file.

Step 2: Code your static libraryFirst we need to add some files. Add a new NSObject subclass to your project and name it StaticClass.Then Write some useful code in those files.

Step 3: Building And Distributing Your LibraryOnce you are happy with your library, simply build it in XCode. Obviously, don’t do build and run as you can’t run it (again unless you have a test suite). Now, look under the Products group in XCode and you should see a file called lib(libraryName).a. In our case, it’s libstaticlibrary.a.

Right click on that file and select “Reveal In Finder”. Drag this file into a new folder that you create where you will be bundling all of your library files.Now, do the same with all of the .h files. In our case, just copy StaticClass.h into this new directory. Your directory structure should now look like:

FolderName|- libstaticlibrary.a|-  StaticClass.h

Now you can zip this folder and sell it to would-be iOS developers for millions!

Step 4: Linking Your Library In A New ProjectSo now that you have built your shiny new static library, it’s time to test it out in another application.

Create a new View-Based project (or whatever it doesn’t really matter). Name it as Test.

Now, just drag this folder into the project and XCode will set up all of the linking automatically. When prompted to copy, I usually say yes, but you can do whatever you want depending on how you intend on using the library. Sometimes just linking and not copying is far more beneficial if you have multiple projects sharing a single library. It ensures that they all use the most up to date version.

You should now see the .a file along with the header files in the new project.

Step 5: Using The Static Library Code

Now that all of the linking is set up, you just use your library like any other class.
