It means that returning ‘void’ and take single parameter of type int.

what does the following mean ?

-(void) myfunction:o

Answer 1

it translates to

- (void) myfunction:(id) o

For example, the method

-(void) myfunction:o:p:q {
    NSLog(@"%@, %@, %@", o,p,q);
}

When called with

[self myfunction:@"test" :[NSNumber numberWithInt:4] :nil];

Prints out:

2012-04-14 08:02:20.470 Test[36499:f803] test, 4, (null)
