Access Outlets from a different class - objective-c

Question

So heres my issue. I assume its a simple one but i just cannot figure out why this is not working.
I need to access Outlets (UITextField, UITableView, UIActivityIndicatorView, etc.) in one class (RootViewController) from a different class (ServiceController).
I have this currently (only showing whats need) :
RootViewController.h
#interface RootViewController : UIViewController{
UITextField *textField;
}
#property (nonatomic, retain) IBOutlet UITextField *textField;
- (void)startService;
#end
RootViewController.m
#implementation RootViewController
#synthesize textField;
- (void)startService{
ServiceController *service = [[ServiceController alloc] init];
[service start];
[service release];
}
#end
ServiceController.h
#class RootViewController;
#interface ServiceController : NSObject{
}
#property (nonatomic, retain) IBOutlet RootViewController *rootViewController;
- (void)start;
#end
ServiceController.m
#import "RootViewController.h"
#implementation ServiceController
#synthesize rootViewController;
- (void)start{
[((RootViewController*)rootViewController).textField setText:#"HELLO !"];
NSLog(#"CALLED !");
}
#end
I do not see why this is not working, i use the same method to do the same thing from the RootViewController to the DetailViewController and it works fine. I checked to see if there were any other declaration in the detail/root controllers to allow that to work but i did not notice any.
PS: everything is being called successfully and "CALLED !" is being logged, just whatever i do to the outlet(s) has no effect.

Answer 1

Your ServiceController needs to have its rootViewController property set. You can either do this in an XIB file or explicitly in code:
myServiceController.rootViewController = myRootViewController;

Answer 2

It looks like you didn't set the rootViewController.
Try adding :
ServiceController *service = [[ServiceController alloc] init];
// set the property here
[service setRootViewController:self];
[service start];
[service release];
