Thanks in Advance.

Have you specified that the File's Owner is of type sample? You can do that on the Identity tab in Interface Builder.

If sample is not a subclass of UIViewController you would most likely add an NSObject in Interface Builder and then set the Type to sample. You would also most likely have to add an IBOutlet to your view controller/File's Owner of type sample and connect it to the sample object in IB.

You want to make a function called on button press event.

so declare method in .h file as -(IBAction) click:(id)sender

then it shows in file's owner inspector.Make connection with button for touchUpInside.
