Assertion failure in -[UITableView _configureCellForDisplay:forIndexPath:]
今天做一个tableView遇到一个这么个问题。
经过baidu google,终于找到正解。
因为
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
这个函数的返回值是个null!!
查stackoverflow 找到下面的解。
CellIdentifier I bet your cellForRowAtIndexPath is returning null.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Photos";
/** NOTE: This method can return nil so you need to account for that in code */
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// NOTE: Add some code like this to create a new cell if there are none to reuse
if(cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
NSString *string = [[self.photosInPlace objectAtIndex:indexPath.row] valueForKeyPath:@"description._content"];
cell.textLabel.text = string;
return cell;
}
That's probably why [UITableView _configureCellForDisplay:forIndexPath:] is failing... becausecellForRowAtIndexPath is returning a null value and then configureCellForDisplay is expecting aUITableViewCell.
