ios 11 아이 폰 x 와 관련 된 적합 한 문제 및 해결 방법

iOS 11 에 관 한 가장 큰 변 화 는 안전 구역(safeArea)이라는 개념 을 증가 시 켰 다 는 것 이다.iOS 11 이 적합 한 대부분의 문 제 는 이 로 인해 발생 한 것 이다.
ios 11 에서 table View 는 알 수 없 는 오프셋,해결 방법:

//  iOS11 tableview     ,       0 
 self.tableView.estimatedRowHeight = 0; 
 self.tableView.estimatedSectionHeaderHeight = 0; 
 self.tableView.estimatedSectionFooterHeight = 0; 

scrollView 를 해결 합 니 다.기본 위치 가 바 뀌 었 습 니 다.해결 방법:

-(void)setScrollViewContentInsetAdjustmentBehavior:(UIScrollView *)scrollView { 
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 110000 
 if(@available(iOS 11.0, *)) { 
  if ([scrollView respondsToSelector:@selector(setContentInsetAdjustmentBehavior:)]) { 
   scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever; 
  } 
 } 
#endif 
} 

아이 폰 x 어댑터 에 대해 클래스 를 봉 인 했 습 니 다.코드 는 다음 과 같 습 니 다.
