ios - How can I programmatically set dataSource of UITableView? -


I have a strange problem. I am trying to allocate a data source on a program basis.

I have created a UITableView and an IBOuttlet in my ViewController using an interface builder for this. I have created a class that implements UITableViewDataSource . I set my table's dataSource to be an example of the data table

error thread 1: EXC_BAD_ACCESS (code = EXC_i386_GPFLT) and Class is executed in runtime. AppDelegate Define line is highlighted. 

  View category Controller: UIViewController {@IBOutlet weak var table: UITableView! Override func viewDidLoad () {ds = MyData () table.dataSource = ds // & lt; ---- Runtime error table .reloadData () super.viewDidLoad ()} // // Other methods} class MyData: NSObject, UITableViewDataSource {func tableView (table view: UITableView!, NumberOfRowsInSection section: int) - & gt; Int {return 5} func tableView (Tableview: UITableView!, CellForRowAtIndexPath indexPath: NSIndexPath!) - & gt; UITableViewCell! {Cell = UITableViewCell () cell.textLabel.text = "a row" return cell}} Any idea why I am getting this runtime error? I am using XCode 6 Beta 4 with Swift.   
 
 
 Change your code to:  
  View class controller: UIViewController {@Iboutlet Weak var table: UITableView! Var Data Source: MyData? Override func viewDidLoad () {super.viewDidLoad () data source = MyData () table.dataSource = DataSource! }}  
 
 Your app breaks because the  DS  is returned to the  viewDidLoad  return as soon as possible. You have to keep the context of your data source.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
