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

Question

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

I tried doing this but couldn\'t do it.

Thanks in advance

Answer 1

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 library First 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 Library Once 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 Project So 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.
