c# - 单点触控 : uncaughtExceptionHandler?

Question

在 MonoTouch 中，如何注册未捕获的异常处理程序(或类似函数)

在 Obj-C 中:

void uncaughtExceptionHandler(NSException *exception) {
      [FlurryAnalytics logError:@"Uncaught" message:@"Crash!" exception:exception];
  }

- (void)applicationDidFinishLaunching:(UIApplication *)application { 
     NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
     [FlurryAnalytics startSession:@" "];
    ....
}

    public delegate void NSUncaughtExceptionHandler(IntPtr exception);

    [DllImport("/System/Library/Frameworks/Foundation.framework/Foundation")]
    private static extern void NSSetUncaughtExceptionHandler(IntPtr handler);

    // This is the main entry point of the application.
    private static void Main(string[] args)
    {
            NSSetUncaughtExceptionHandler(
                Marshal.GetFunctionPointerForDelegate(new NSUncaughtExceptionHandler(MyUncaughtExceptionHandler)));

            ...
    }

    [MonoPInvokeCallback(typeof(NSUncaughtExceptionHandler))]
    private static void MyUncaughtExceptionHandler(IntPtr exception)
    {
        var e = new NSException(exception);
        ...
    }
