Iphone – Developing a calculator

Hello guys this is my first app in iOS 4. Is a simple calculator. Feel free to ask question about the code. Right after I finished this app I learned about dot notation in Object-C so I still have to implement it.

Enjoy.

Minha primeira aplicação em iOS4. Se tiver qualquer duvida ou pergunta não exite em deixar um comentário.
