I am a beginner in native development.I made a project using xcode in objective C.It builded successfully.But when I run the project ,an error came like 'unrecognized selector sent to instance'.Why this is happening ?can anyone help me to solve this?I am attaching the error that I am getting with this..

And I am posting the code with this....
