Question

I have written two classes which contains same method (print). I want to access first class print method using second class object. How i can achieve this?

Code:

@interface classA : NSObject
-(void) print;
@end

@implementation classA

-(void) print
{
    NSLog(@"hello");
}

@end

@interface classB : classA

-(void) print;
@end

@implementation classB

-(void) print{
    NSLog(@"hey");
}
@end

Now i created second class object like

classB *B = [classB alloc]init];
