Showing a view controller modally in monotouch
In my Monotouch based iOS project , i have 2 view controllers .On first ViewController i have created a button by xib. Now on selection of this button i want to display the second view controller but it is not happening and it causes the application to crash.
So in my design.cs file this is the way the button is created
[Outlet]
MonoTouch.UIKit.UIButton firstButton { get; set; }
[Action ("clickMe:")]
partial void clickMe (MonoTouch.Foundation.NSObject sender);
This is in my button action method in .cs file, which is causing the crash.
partial void clickMe (MonoTouch.Foundation.NSObject sender)
{
SecondViewController secondViewControllerObject=new SecondViewController();
this.PresentViewController(secondViewControllerObject, true, null);
}
Error Description :-
Got a SIGABRT while executing native code.
Terminating runtime due to unhandled exception

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

The key bit of information in your exception is:
this class is not key value coding-compliant for the key butnSubmit
Which means that you have a property on your C# class which doesn't have a corresponding outlet in the .xib (interface builder) file.
Re-check/recreate your outlets, and see if that solves the problem.
