如何解決Thread1：SIGABRT信號？與此行[[NSBundle mainBundle] loadNibNamed：@「DVDListingView」owner：self options：nil];

Question

可能重複：
How do you load custom UITableViewCells from Xib files?

這裏是我的代碼..

// Customize the appearance of table view cells. 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

    static NSString *CellIdentifier = @"LibraryListingCell"; 

    DVDListingViewCell *cell = (DVDListingViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     [[NSBundle mainBundle] loadNibNamed:@"DVDListingView" owner:self options:nil]; 
     cell = [_cell autorelease]; 
     _cell = nil; 
    } 

    cell.titleLabel.text = [[dao libraryItemAtIndex:indexPath.row] valueForKey:@"title"];  
    cell.featureLengthLabel.text = [NSString stringWithFormat:@"%@ minutes", 
            [[dao libraryItemAtIndex:indexPath.row] valueForKey:@"featureLength"]]; 
    cell.coverImageView.image = [UIImage 
           imageNamed:[[dao libraryItemAtIndex:indexPath.row] valueForKey:@"coverImage"]]; 

    return cell; 
} 

如何解決線程1：這條線[一個NSBundle mainBundle]信號SIGABRT問題loadNibNamed ：@「DVDListingView」擁有者：self options：nil];

我會建議試試這個，同時確保您「DVDListingView.xib」 是筆尖的自定義單元格ONLY

// Customize the appearance of table view cells. 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

    static NSString *CellIdentifier = @"LibraryListingCell"; 

    DVDListingViewCell *cell = (DVDListingViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"DVDListingView" owner:self options:nil]; 
     for(id currentObject in topLevelObjects){ 
      if([currentObject isKindOfClass:[DVDListingViewCell class]]){ 
       cell = (DVDListingViewCell *)currentObject; 
       break; 
      } 
     } 
    } 

    cell.titleLabel.text = [[dao libraryItemAtIndex:indexPath.row] valueForKey:@"title"];  
    cell.featureLengthLabel.text = [NSString stringWithFormat:@"%@ minutes", 
            [[dao libraryItemAtIndex:indexPath.row] valueForKey:@"featureLength"]]; 
    cell.coverImageView.image = [UIImage 
           imageNamed:[[dao libraryItemAtIndex:indexPath.row] valueForKey:@"coverImage"]]; 

    return cell; 
}

線

[[NSBundle mainBundle] loadNibNamed:@"DVDListingView" owner:self options:nil]; 

返回一個NSArray 。它需要是這樣的：

NSArray *xibObjectArray = [[NSBundle mainBundle] loadNibNamed:@"DVDListingView" owner:self options:nil]; 
//retrieve items from the array 
if (xibObjectArray.count == 1) { 
    cell = [xibObjectArray objectAtIndex:0]; 
} else { 
    for (UIView *randomView in xibObjectArray) { 
     if ([randomView isKindOfClass:[DVDListingViewCell class]]) { 
      cell = (DVDListingViewCell *)randomView; 
     } 
    } 
}
