部分问题是您要搜索的是UITableView而不是UITableViewCell.

I am using xCode 4.2 to build an iPhone app.

Related Question - I think this might be the REAL problem I'm experiencing: Why does tableView dequeueReusableCellWithIdentifier:CellIdentifier return null?

But let me continue with this quesiton anyway:

There's something about the line [[NSBundle mainBundle] loadNibNamed:@"WSCSessionCell" owner:nil options:nil]; that gives me a SIGABRT error when I set up the rootviewcontroller in a certain way and not another way. Let me start with sample code from my WSCSessionTable which inherits UITableViewController:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"WSCSessionCell";

    WSCSessionCell *cell = (WSCSessionCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

        NSArray * topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"WSCSessionCell" owner:nil options:nil];

        for(id currentObject in topLevelObjects)
        {
            if([currentObject isKindOfClass:[UITableView class]])
            {
                cell = (WSCSessionCell *) currentObject;
                break;
            }
        }

    }
return cell;
}

Scenario 1 - No Problem - No SIGABRT

The code above works fine when my NavigationController rootviewcontrols WSCSessionTable. Here's what my storyboard looks like for reference.

Scenario 2 - Problems, Code causes SIGABRT

The above code causes a SIGABRT error when I put a UIViewController between the navigation controller and WSCSessionTable. I then use a button to instantiate WSCSessionTable. here's my story board set up

This is the event handler for the button

- (IBAction)goToSession:(id)sender
{
    wscAppDelegate *appDelegate = (wscAppDelegate *)[[UIApplication sharedApplication] delegate];
    UIStoryboard * storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
    wscSessions *childView = [storyboard instantiateViewControllerWithIdentifier:@"sessionstable"];
//    wscSessions *childView = [storyboard instantiateViewControllerWithIdentifier:@"sessionstable"];
    childView._arrData = appDelegate._arrSession;
    childView._arrSpeaker = appDelegate._arrSpeaker;
    childView.title = @"SEssions";
    [self.navigationController pushViewController:childView animated:YES]; 
    }

I get a sigabrt error in in the cellforrowatindexpath function on the line with the nsbundle mainbundle. Here's the error output

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/dduvernet/Library/Application Support/iPhone Simulator/5.1/Applications/54EF04FD-E010-48BB-A0F4-EB0F12BF8D6A/gmmiphone.app> (loaded)' with name 'WSCSessionCell''

 Does anyone know how I can instantiate WSCSessiontable via button tab down?

解决方案

Part of the issue is that you are searching for a UITableView instead of a UITableViewCell.
