Question

我有一个tableView，它以两个空数组开始（storageData＆amp; descripData - 因为用户尚未添加任何项目）。现在当我的用户添加一个项目（标题，描述和照片）并刷新tableView时，我收到错误：

' - [__ NSCFArray objectAtIndex：]：index（1）超出bounds（1）'

那就是说，我不确定为什么。见下面的代码;谢谢！

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if ([self.storageData count] > 0 && self.descripData.count > 0)
    {
        return [self.storageData count];
    }
    else
        return 1;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *DoctorsTableIdentifier = @"StorageItemTableViewCell";

    StorageItemTableViewCell *cell = (StorageItemTableViewCell *)[tableView dequeueReusableCellWithIdentifier:DoctorsTableIdentifier];
    if (cell == nil)

        {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"StorageItemTableViewCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
        }

   if (self.storageData.count > 0 && self.descripData.count > 0) {

        noitemsView.hidden = YES;

            NSDictionary *tmp = [self.storageData objectForKey:[NSString stringWithFormat:@"%d",(long)indexPath.row]];


       [[cell itemName] setText:(NSString *)[tmp objectForKey:@"title"]];

              NSString *title = [tmp objectForKey:@"title"];
            [[cell itemName] setText:title];

            NSDictionary *node = [self.descripData objectAtIndex:indexPath.row];
            [[cell itemDescrip] setText:[node objectForKey:@"body"]];
            NSLog(@"%@", self.descripData);

            NSString *secondLink = [[self.descripData objectAtIndex:indexPath.row] objectForKey:@"photo"];

            [cell.itemPhoto sd_setImageWithURL:[NSURL URLWithString:secondLink]];

            NSLog(@"%@",secondLink);


              }

    else {
        noitemsView.hidden = NO;
    }
    return cell;

              }

Answer 1

仔细观察self.descripData.count，因为在numberOrRowsInSection中你返回了[self.storageData count]。但似乎是self.storageData.count＆gt; self.descripData.count，因此您尝试获取self.descripData bounds之外的对象。这么简单。

Answer 2

在storageData方法中，如果storageData.count > 0和descripData.count > 0，则会返回NSDictionary *node = [self.descripData objectAtIndex:indexPath.row];的计数。

正如你所说，它在self.storageData.count > self.descripData.count

这一行崩溃了
