我有一个非常简单的应用，只包含 UITableView 及其 UITableViewSource ..
使用UITableView而不链接到UITableViewSource（应用程序在模拟器和设备中工作）
但是当我将UITableView链接到UITableViewSource时（应用在模拟器中工作但在设备上崩溃）
（该设备 iPad 正在运行IOS 9.2.1）
它给了我这个长时间的错误：

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
我的所有项目只包含2个视图：）
ViewController.cs ：
using System;
using UIKit;
namespace secondApp
{
public partial class ViewController : UIViewController
{
public ViewController (IntPtr handle) : base (handle)
{
}
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
string[] list = new string[]{"Red", "Blue", "Brown", "Green" };
UITableView table = new UITableView {
Frame = new CoreGraphics.CGRect (0, 0, View.Bounds.Width, View.Bounds.Height),
Source = new myTableSource(list) // the problem happens when I add this line
};
View.AddSubview (table);
}
public override void DidReceiveMemoryWarning ()
{
base.DidReceiveMemoryWarning ();
}
}
}
和 myTableSource.cs ：
using System;
using UIKit;
namespace secondApp
{
public class myTableSource : UITableViewSource
{
string[] TableItems;
string CellIdentifier = "TableCell";
public myTableSource (string[] items)
{
TableItems = items;
}
public override nint RowsInSection (UITableView tableview, nint section)
{
return TableItems.Length;
}
public override UITableViewCell GetCell (UITableView tableView, Foundation.NSIndexPath indexPath)
{
UITableViewCell cell = tableView.DequeueReusableCell (CellIdentifier);
string item = TableItems[indexPath.Row];
if (cell == null){
cell = new UITableViewCell (UITableViewCellStyle.Default, CellIdentifier);
}
cell.TextLabel.Text = item;
return cell;
}
}
}
希望这个错误有一个简单的解决方案，因为我还在学习 Xamarin
的第一步提前致谢..
答案 0 :(得分：0)
经过近一周的时间问题已经解决，相同的解决方案在相同设备上完美运行...
我只做了Build -> Clean All ..也许它解决了问题，或者问题可以通过等待一周来解决
