我有一个非常简单的应用程序,它只包含UITableView和它的UITableViewSource ..
当使用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(应用程序在模拟器中工作但在设备上崩溃)
(该设备是运行IOS 9.2.1的iPad)
它给我这个长的错误：

================================================================= 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,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;
}
}
}
希望有一个简单的解决方案来解决这个错误,因为我还是在学习Xamarin的第一步
提前致谢 ..
解决方法
几乎一个星期以后,问题本身就消失了,相同的解决方案在同一台设备上完美地运行…
我只做了Build – >清洁所有..也许它解决了问题,或者也许问题解决了只是等待一个星期
