600 행을로드 한 후 UITableview 페이징 크래시 응용 프로그램

Question

하나의 주요 문제가 있습니다. 내가 페이징으로 uitable보기를 구현했지만 내가 행 700 응용 프로그램에 충돌 때로는 ipad를 다시 시작 충돌. 그래서 모든 것을 시도했지만 해결책을 얻지 못하고 있습니다. 이것은 내 코드입니다.

이것은 셀을 채우는 데 사용하는 NSObject입니다.

그리고 이것은 페이징을 위해 필링 어레이에 사용하고있는 나의 방법입니다.

Answer 1

당신은 당신의 세포를 재사용해야

이 충돌 로그입니다. 너무 많은 UITableViewCells 메모리에로드 된 및 메모리 경고 후 충돌합니다.

데이터의 700 행을로드 할 때 셀 식별자 (index + row)는 700만큼의 셀을 만듭니다. 셀 식별자는 화면에 표시된 셀 수에 대해 고유해야합니다. 가장 좋은 점은 다른 쉽고 반복적이지 않은 셀 식별자를 가질 수 있다는 것입니다. 그래서 세포는보다 효율적으로 재사용됩니다.

동일한 UITableViewCell을 사용하려고하지만 표시 할 정보와 일치하는 레이블 및 detailLabels를 변경하십시오.

Answer 2

살펴볼 가치가있는 한 가지는 코드에서 dequeueReusableCellWithIdentifier 사용입니다. 내가 셀 섹션과 행을 식별자로 사용하고 있기 때문에 각 데이터 항목에 대해 새 셀을 생성한다고 말할 수 있습니다. 이것에 대한 이유가 있습니까? 셀이 시각적으로 같으면 (각 셀의 데이터 만 다름) dequeueReusableCell 식별자가 각 셀에 동일하도록이 값을 변경하십시오. 이를 통해 OS는 셀의 메모리를보다 효율적으로 관리 할 수 ​​있습니다.
