When I write Android apps, I love the Toast feature. Is there a way to get this kind of set and forget popup message in iPhone development using MonoTouch (C# .NET)?
You might be after Local Notifications, pretty sure they allow you to set a time, I think in epoch time to be fired off. Don't think there is a way to hide them though. I might be misunderstanding your question though cause I'm unfamiliar with Toast.
