getting string from one ViewController to another?

Question

I have been working on my application for a while now. I am stuck on this small problem: setting my text field's text isn't working.The string of the text field is called from another viewcontroller Here is what my code looks like:

1st view controller -(void)setURL:(NSURL *)src { downloadSourceField.text = src; } 2nd view controller

if ([[booksArray objectAtIndex:indexPath.row] isEqual:[NSString stringWithFormat:@"%@",song_1]]) 
{
    NSString *sc1 = [NSString stringWithFormat:@"tst 1"];
    [tc setURL:sc1];
}

else 
{
    NSString *sc = [NSString  stringWithFormat:@"test 2"];
    [tc setURL:sc];
}

If the text field is created in Interface Builder, double check the connection. Sending a message (setText: in this case) to a nil object will fail silently. — Sam

I have made the text field in the interface builder and have made sure it is all hooked up to it outlets and everything — Tushar Chutani

Are you getting errors? If not, set a breakpoint on that line and check the variables. I would suspect that either downloadSourceField or src is nil (0x0). — Pieter Jongsma

downloadsourcefield is set to nil and that is what i am trying to change and set it to the text that is stored in src — Tushar Chutani

okay now when i nslog the src it works fine but now when i try to put it in the uitextfield it changes to (null) for some reason — Tushar Chutani

I think you're trying to assign an NSURL object to an NSString variable. What you should do is

downloadSourceField.text = [src absoluteString];

The absoluteString method will convert your NSURL into an NSString representation.
