이것은 나를 미치게합니다!iOS [__NSArrayM insertObject : atIndex :] : 객체가 무효가 될 수 없습니다.

내가보고 있어요 '* - [__ NSArrayM은 insertObject : atIndex :] : 객체가 될 수 없다 전무'

확실하지, 이전 빌드로 복원했지만 다른 워크 스테이션에서 여전히 아래 코드에서이 오류가 발생했습니다.

아이디어가 있습니까?

[imgArray addObject:img1];

이 img1가 nil 것을 의미 오류가 행하므로

(따라서 급격한 엔딩 파일 트림했다). 당신이 subview.photo.image에서 img1를 얻을 수 있기 때문에이 세 가지 중 하나를 의미

  1. subview.photo.image이 nil입니다.
  2. subview.photo은 nil입니다.
  3. subview은 nil입니다.

방금 ​​subview을 생성 했으므로 아마 # 3이 아닙니다. 당신이에서 subview.photo를 얻을 수 있기 때문에 :

[[IMLocalUser localUser] cachedPhotoAtIndex:0];

이이 nil이 아닌 값을 반환하는지 확인해야합니다. 0이 아닌 경우 image 속성이 nil이 아닌지 확인하십시오.

사이드 참고 :

이 두 라인 :

UIImage *img1 = [[UIImage alloc] init]; 
img1 = subview.photo.image;

이 낭비 UIImage을 만들 수 있습니다. 그냥하세요 :

UIImage *img1 = subview.photo.image;

이상한 점은 때로는 괜찮습니다. 그리고 다른 것들은 IMG4에서 충돌 할 것입니다. – danielsteel
