On the type of problem SEL

I would like to ask a question Bucai, SEL type can not save to the array (NSArray) passed along inside it
For example
I was in a class A which defines
- (Void) a;
- (Void) b;
- (Void) c;


I want to make the inside of another Class A Class B call it under certain conditions the method
- (Void) pressed: (id) target method: (SEL) method ----> this makes possible

But I want all of the methods A and making a pass over
SEL array
SEL do not know what can be saved to an array inside?

Should also be placed directly after the turn into NSString certainly
