그리고 문제의 속성 코드 여기

cell.imageURL=[NSURL URLWithString:self.imageURLs[indexPath.row]]; 

의 라인 세터

와

@property(strong,nonatomic) NSURL *imageURL; 

임 인스턴스로 전송

-(void)setImageURL:(NSURL *)imageURL 
{ 
    _imageURL=imageURL; 
    [self startDownloadingImage]; 
} 

이상한 것은이 작업에 사용되며 약 1 시간 정도 전에 작동을 멈추고이 예외를 던지기 시작합니다. 당신의 세포가 실제로 UITableViewCell 인스턴스 아닌 사용자 정의 셀 클래스의 인스턴스이기 때문에

갱신

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    BCDDogImageTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[BCDDogImageTableViewCell cellPrototypeIdentifier] forIndexPath:indexPath]; 
    NSLog(@"THE CELL IS: %@ ", cell); 
    cell.imageURL=[NSURL URLWithString:self.imageURLs[indexPath.row]]; 
    return cell; 
} 

Answer 1

오류입니다.

셀의 사용자 정의 셀 클래스를 등록하십시오.
