엑스 코드 주소 : @ ""`

Question

엑스 코드 8 주소 소독제를 활성화, 내가 다음 코드 줄에서 문제를 어떻게해야합니까 :

UIImage *myImage = [UIImage imageNamed:imageName]; 

imageName가 따라있는 NSString입니다 이미지가 @ 1x, @ 2x, @ 3x에 존재합니다. 주소 살균제 문제 :

존재하지 않는 imageName을 사용하면 주소 살균기는 해당 줄에 아무런 문제가 없습니다.

문제는 iOS 8에만 영향을 미치는 것으로 보이며, 주소 살생자는 iOS 9 및 iOS 10 (최신 베타)에 문제가 없습니다. iOS 8에서는 이미지를 애셋에 넣지 않고 직접 번들에 넣을 때도 작동합니다.

Answer 1

이것은 Xcode 8 Beta 6 (8S201h)의 버그 인 것 같습니다. iOS 8.3으로 앱의 배포 대상을 UIImage imageNamed:으로 설정하면 참조 된 이미지가 애셋 카탈로그에서 오는 경우 오류가 발생합니다. UIImage imageNamed:inBundle:compatibleWithTraitCollection:을 사용하면 효과가 없습니다.

• 설정 전개 대상 < 아이폰 OS 8.3. 이 문제에 대한 예제 프로젝트에서 찾을 수 있습니다
