Question

In MonoTouch, how do I register an uncaught exception handler (or similar function)

In Obj-C:

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

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

Answer 1

You add a try-catch handler around the code that (might) throw NSExceptions:

try {
    FlurryAnalytics.StartSession (" ");
} catch (MonoTouchException ex) {
    Console.WriteLine ("Could not start flurry analytics: {0}", ex.Message);
}

MonoTouch already installs an uncaught exception handler, and automatically translates those ObjectiveC exceptions to managed exceptions.
