How should an IPhone notification-type application show user there is a notification unobtrusively

I have a program that basically just queries a webservice, and if any data is returned it will show that information to the user, but if there is nothing to display it will just wait until the next scheduled time and run.

Right now it just puts a table in front of the user, there is nothing in the status bar that they can then se开发者_运维百科lect and see the actual information.

So, I have two questions.

1. Is there a better way to show notification information to a user that is less intrusive?
2. Should the View, with a UITable, have a button to dismiss the view when they are finished?

UPDATE:

It seems my question isn't clear enough, so I have the data showing up in the table properly.

My problem is before I display the data.

Currently, periodically the timer will fire off my method, and if there is any events pending for the user the table will show up right in front of them.

That is bad design, IMO, so what I would like is some simple way to let them know that there is something pending and they can look at it when they get a moment.

Ideally I would have something in the status bar to show that they have some events, but it appears that isn't an option that I can see.

One option is to see if I can have the table come up minimized and have some sound or vibration go off, but again that can be bothersome to the user, as it may interrupt what they are doing.

The proper solution appears to be that while in the background just put up a notification if there is any new information, so the user can close the notification or switch to view the details.

This isn't the ideal solution, but appears to be the best choice on the iPhone.
