Question

I have an iPhone app with a tableviewcontroller. When you click a certain cell it opens a new uiviewcontroller with this code:

 nextViewController = [[avTouchViewController alloc] initWithNibName:@"avTouchViewController" bundle:nil];

The uiviewcontroller above called avTouchViewController has a property that looks like:

IBOutlet SomeObject *controller;

SomeObject is an object with all relevant view properties.

I would like to pass an nsstring parameter from the tableviewcontroller I initialize the avTouchViewController with to someObject.

How can I do this?

I’m a little confused by your question; you say you’re creating your avTouchViewControllers when a cell is tapped inside an existing UITableView, but your last part describes the inverse situation.

Basically, if you want to pass information to a view controller, just give it a property that can be set (which may already be the case), e.g.:

nextViewController = [[avTouchViewController alloc] initWithNibName:@"avTouchViewController" bundle:nil];
nextViewController.controller = theInstanceOfSomeObjectIWantToPass;

You also may want to rename your controller property. To a reader, it doesn’t make sense that a view controller has a property called controller which is actually a SomeObject*. As well, your class names should be capitalized, i.e. use AvTouchViewController instead of avTouchViewController.
