Passing a NSString to NSObject - ios

Question

I am having a hard time figuring out how to pass a NSString to a NSObject class.
I have a .h and .m file which is a NSObject and I need to pass a string from a UIViewController.
This is what I tried when pushing the view:
NSString *urlString = #"TextHere";
WXClient *svc = [[WXClient alloc]init];
svc.urlOne = urlString
And then, I am retrieving it this way:
#interface WXClient : NSObject {
NSString *urlOne;
}
#property (strong, nonatomic) NSString *urlOne;
and of course, then on the .m :
#synthesize urlOne;
Then to use the NSString:
NSString *urlString = [NSString stringWithFormat:urlOne];
NSURL *url = [NSURL URLWithString:urlString];
//blah blah blah blah... :D
}];
But for some reason it is returning null. I am able to use this method from viewController to viewController but to NSObject is not working :(
Any ideas?
Thanks!

Try this
WXClient *svc = [[WXClient alloc]init];
NSString *urlString = #"TextHere";
svc.urlOne = urlString;
Sorry didn't read question properly

If you are pushing/presenting view controller throug segue and you want to send some data to destination view contrller. Like you want to set some property, you need to implement this method. prepareForSegue:sender:.
In it you you can get destination viewController and set whatever property you want to.
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"weatherWXID"]) {
WeatherViewController *vc = [segue destinationViewController];
NSString *urlString = #"TextHere";
WXClient *svc = [WXCLient new];
svc.urlOne = urlString
vc.wxclient = svc;
}
}
