내 tableView에서 셀을 선택하고 셀이 강조 표시되면 셀이 강조 표시 될 때 테이블을 스크롤 할 때 그 이유를 필사적으로 시도합니다. "Arts and Museums"또는 "Coffee and Bakeries"를 예로 들자면 -[__NSArrayM objectAtIndex:]: index 6 beyond bounds [0 .. 2] 오류가 발생합니다. 두 범주 모두 3 가지 값을 포함하므로 [0 .. 2]을 얻을 수는 있지만, 왜 그런 일이 발생하는지 이해할 수 없습니다. 콘솔에서 볼 수있는 것처럼 앱이로드되면 총 10 개의 셀 (각 카테고리 당 1 개)이 생성됩니다. 컴파일러 하이라이트이 라인 오류가 발생하면 아래 cell.textLabel.text = [arrayNo objectAtIndex:indexPath.row]; 코드 ...NSMutableArray로 작업 할 때 "경계 너머"오류가 발생했습니다.

} 나는 .. 나는이 GestureRecognizer 제거, 그냥 얻을 말할 것을 생각한다면
- (void) reLoad
{
[self.myTableView reloadData];
}
고마워요! 나는 그것을 조사 할 것이다. 내 유일한 생각은 적어도 뒤로 탐색 (doubletap)을 위해 GestureRecognizer를 사용하고 싶지만, 아마도 대안을 탐색 할 것입니다. – Greg
