Question

@interface A : NSObject

- (void) tmp;
- (void) foo;

@end

@implementation A

- (void) tmp {
    [self foo];
}

- (void) foo {
    NSLog(@"A");
}

@end

derived class

@interface B : A

- (void) foo;

@end

@implementation B

- (void) foo {
    NSLog(@"B");
}

@end

code

B * b = [[B alloc] init];
[b tmp]; // -> writes out B

is there a way to implement A, so a call to [self foo] inside [self tmp] in class A would result in calling A:foo not B:foo

(so the output after calling [b foo] == @”B” and after calling [b tmp] == @”A”)

smth like

@implementation A

- (void) tmp {
    [ALWAYS_CALL_ON_A foo];
}

Answer 1

You can use super

@implementation B

- (void) tmp {
     [super foo];
}
@end
