The action method you are writing must be associated with a class. Go to the implementation (.m) file of this class in Project Builder. Put your action method after the # import and @implementation line and before the @end line. Any number of action methods can be put between @implementation and @end and the order does not matter.

#import “MyView.h”

@implementation MyView

• (IBAction) myMethod:(id)sender { // here you write your code, optionally making use of sender }

@end
