내 didBeginContact 메서드는 공이 충돌 할 때 내 벽돌 스프라이트를 제거해야합니다. 그러나 그것은 그 일을하지 않습니다. 내가 그것을 실행할 때, 패들을 치고 벽돌을 때릴 때 NSLog "패들 (paddle)"을 얻습니다. 코드를 여러 번 살펴 봤는데 누군가가 여기에 참여하는 걸 말해 줄 수 있습니까?didBeginContact 메서드가 작동하지 않습니다.

'notTheBall'가 contact.bodyA' '로 설정되어야 할 때'조건 if' 거짓입니다. – 0x141E
그래, 그걸 알아 냈고 답을 올렸습니다. 감사합니다 @ 0x141E –
