iOS Problem when migrate iPhone app to iPad device

[utklyf]

Hi, I was trying to migrate a simple helloworld app from iPhone to iPad. (I have used the 'two device-specific applications' model)

It works well with iPhone simulator 3.2 (the iPad simulator). But after I installed it onto a real iPad device, it just doesn't work. The app cannot get started.

below is my code, thanks a lot

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
	
	[[cell textLabel] setText:@"helloworld"];
	
    return cell;
}

Care to post the rest of the code? The crash report? SOMETHING that will help people help you? What you posted may have no impact at all on what your real problem is?

Sure!! The complete class is in follows. I didn't get any crash report. But I have taken 5 pictures of this app. The 1st is what it looks like on iPad simulator, the 2nd - 5th are what it performed on iPad device.

You can see that it works well on simulator, but on iPad device, when I click on it, the icon will fly out and then come back again. But the cells and the words 'hello world' never show up.

Many thanks

If it's going right back to the Springboard it is crashing, and there should be a report. When you have your iPad hooked up, go into Organizer and view the crash reports, you should see one for your app.
