안녕하세요 여러분, 큰 문제가 있습니다. 저는 iPad 앱을 개발 중입니다. 이것에서 나는 UITableView에서 테이블 뷰 셀을 재사용했다. 이전에는 셀을 재사용하지 않았지만 작동했지만 매우 느립니다. 나는 세포를 rused 한 성능을 향상시키기 위해 지금은 매우 빠르고하지만 난 후 몇 번이나 속도를 스크롤 할 때 * EXC_BAD_ACCESS * 다음과 같은 메시지가 발생예기치 않은 EXC_BAD_ACCESS 여러 번 스크롤 UITableView
-[CALayer retain]: message sent to deallocated instance 0x5aba7b0
나는 발표되는 실제 함께 IBOutlet을 발견했다. 그것은 UIImageView입니다. 전에도 같은 문제가 셀의 UIButton에있었습니다. 나는 재산을 보유하고 그것을 선언했다. 이제 imageview 유지 선언 할 경우 작동하지만 .. 지금 셀프 홀수 또는 심지어 위치에 따라 imageViews 2 형식이 필요합니다. 이제는 연속 된 3,2,4 ...에서의 동일한 이미지 뷰를 보여줍니다. 고정되지 않은 셀. 나는 다음 코드를 도와주세요 문제 strugling 오전 :
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
Defect* defect=nil;
if(defects && [defects count]>0){
defect=[defects objectAtIndex:indexPath.row];

cell = [tableView dequeueReusableCellWithIdentifier:defect.cellIdientifier];
