Hi, I got a basic doubt regarding the selectors of the button (uibutton) action. i) I had observed that selector method can be used without having the declaration in the .h file. Is there any logic behind the frame work of iphone sdk in this matter. ii) Also, return values I have seen are IBAction, id and void. Where does the actual value is returned, and how can we use the returned id value. Can any one please make the Basic questions clear.. Thanks.
