How can i do this.. I am new to iphone .. Pls anybody help me..

Answer 1

if i am using SEL as the datatype what attributes should i give for the @property...

A SEL is not an NSObject, so it must be assign.

or can i declare this as a static variable...

You can declare anything as static variable.
