objective-c method name in a protocol UIActionSheetDelegate

I'm looking at a method 

  -(void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex

in the interface UIActionSheetDelegate. Is actionSheet a parameter name or part of method name???

Is the following a matching C declaration?

  (void) actionSheetdidDismissWithButtonIndex(UIActionSheet *actionSheet, NSInteger buttonIndex);

In the method actionSheet:didDismissWithButtonIndex: , there are 2 parameters. actionSheet & buttonIndex. A view controller might be delegate of multiple actionSheets, so first parameter tells about the actionSheet which triggered the method. Similarly, an actionSheet May contain multiple buttons, so 2nd parameter tells you, which button was pressed.

For this method:

 -(void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex

This is the C equivalent:

(void) actionSheetdidDismissWithButtonIndex(UIActionSheet *actionSheet, NSInteger buttonIndex);

Both. The full method name is actionSheet:didDismissWithButtonIndex:, so "actionSheet" is part of that. The parameters are actionSheet and buttonIndex.

Is the following a matching C declaration?

Yes.
