[tableView reloadData] next look

Where to write, or do?

Wrong, wrong files you create, you create is
@ Interface ttttViewController: UIViewController,
And this should be done
UITableViewController@ Interface Conferencing: UITableViewController,
If you really want to add a UITableView in UIViewController, you need to add the code!

So when you create the file is built directly TableView

.....
This is in fact an example of code to write a tableview, and the data is loaded on.
No wrong.

Or add a table up, and set the delegate to self and datesource

If a TableView UIView added to the above, according to the 8th floor of the method have to do it, there is no problem

Thank shulianyong, this is an example, I took it a guide >> << iphone application on the realization of a simple example of a table.
His premise is to use the View-based Application template's.
And. Xib the dragged a tableview. Then connect the file's owner two interfaces. Then write the program.

But written, there is a blank, I do not know xcode4 reasons, or what.

Give you examples
UITableView * tableView = [[UITableView alloc] initWithFrame: CGRectMake (10, 40, frame.size.width-20, 200) style: UITableViewStylePlain];
tableView.delegate = self;
tableView.dataSource = self;
[Self.view addSubview: tableView];
[TableView release];

Thank you very much, but I still want to use the example of a method to achieve.
Because I am in. Xlb has added a tableview. Was not xcode3 can be achieved in this case and the application or something else in xcode4 in practice?

Because when you cite ttttViewController, is the direct use of init, this can not refer to your custom XIB,
[[TtttViewController alloc] initWithNibName: @ "ttttViewController" bundle: nil], so it is instantiated with a reference to your custom XIB

This is not the tube, in mainwindow view is automatically loaded in this, this is already built when you create on the.

I have a little debugging your code, the code should not be a problem, I used your code to be a demo, showed no problem.
You might be a way to use xib file error on this issue there are so few points need to be addressed in the xib in

1. File's Owner to be connected with a View, press Ctrl even

DataSource and delegate two properties 2.table should also connect File's Owner


Nothing else should be on the

I use xcode4. Could be the reason?

Gray often thank you, by [Xiaohui _ Xi'an ] online guide, I will table_view the file's owner is connected, the error caused by the program itself is not the problem.
