Create and Use Static Library in iPhone

Hi Friends,

In this tutorial I will show you how to create a simple Static Library in Xcode 3.2 and then how to use it in our project.First,I will be creating a Static Library and then will show you how to make use use of it in our code.I am providing you with the following steps to do so.

Lets Begin,

1.Creating Static Library in iPhone

1. Create a simple Window-based project,we will call it as ‘SampleLib’.

2. Drag all .h and .m files (which you want to include in your library )in the        ‘Classes’ folder of SampleLib project.

3. Right click on ‘Targets’ ->Add ->New Targets…

4. Select ‘Static Library’.

5. Name it as ‘MyLib’

6. Select ‘build’ tab from the newly pop up window.(That window name is ‘Target “MyLib” info’) or select ‘MyLib’ and press ‘windows+I’,you will get the same window i.e. ‘Target “MyLib” info’.

7. In the ‘Linking’ section set ‘Other Linkers Flag’ to ‘-ObjC’.

8. Now you will see MyLib and Mylib.a in your project.

9. Drag all your (only).m files which you added in step2 above to ‘Targets->MyLib->Compile Sources folder.

10. Delete all the files  from Targets->SampleLib->Compile Sources Folder.

11. Right click on Target->’SampleLib’ then Add->Existing Frameworks and select ‘MyLib.a’ framework in the list.

12. Right Click on Targets->SampleLib select ‘Build SampleLib’.

  Now Your Library is created.

2.Using Static Library in iPhone

1. Create new project where you want to use the Library,name it as ‘TestLib’.

2. Drag ‘MyLib.a’ file and all .h files which are included in the library to ‘TestLib’.

3. For every xcode file wherever you are using 'SampleLib' library code,you need give '.mm' extension to it.Because we need to provide.mm extension to all the xcode files instead of '.m'. 

3. Now you can simply use the static library methods by calling them from your ‘TestLib’.
