Pass Data Into Second View Controller

Question

*My Setup:*
I have a tab-bar program; I'm currently focusing on one tab, which has a nav controller
The root controller works as expected. In one of the table view selection methods (didSelectAccessoryButtonAtIndex, or something similar), I initialize one of my classes, which is a subclass of UIViewController with an alloc and custom init. Then I use the pushViewController to push an instance of that class onto the view stack.
*My Issue:*
I can't figure out how to pass the data from my first level controller to the second. I'm using a custom init method, which is an instance method because I have to pass an instance of a view controller to the pushViewController method. The data isn't getting to the second level controller, as verified by some NSLogs.
*Pseudo code:*
FirstViewController.m:
-(void)accessoryButtonPressedAtSomeIndex {
SecondViewController *svc = [[SecondViewController alloc] initWithString:@"Some string"];
pushViewController: svc
SecondViewController.m:
@synthesize string;
-(id)initWithString:(NSString *)someString {
self.string = someString;
NSLog (@"string = %@", someString);
return self;
The NSLog returns NULL.
Obviously some of the code isn't valid, but I don't remember the exact methods. I can post the real code if necessary, but there are a lot of "dependencies" between files. Everything else (pertaining to this problem, although there are some other bugs in my app that I'd appreciate help on too) works. Any suggestions?

Hello musicwind95
Two suggestions :
1) Didn't you forget to do
if (self = [super init] )
return self;
in an init method ?
Otherwise there is nothing to handle your string
2) Put a breakpoint and trace ..
