Transferring String from UIViewController using Segue

I am doing the following:

#ViewController1.m

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
   NSLog(@"Transferring");

   guestViewController *controller = [segue destinationViewController];
   [controller.label isEqualToString:self.num_value.text];
}

However when the view is loaded, the text does not run through or show up in the label. I have done this in past programs and it has worked on Xcode 4. However, for some reason in Xcode 5 it is not working for me. Is there something else that I need to implement to make this work in Xcode?

[controller.string isEqualToString:self.num_value.text];

isEquelToString only check is controler.string is the same or not as self.num.value.text.

- (BOOL)isEqualToString:(NSString *)aString

Returns a Boolean value that indicates whether a given string is equal to the receiver using a literal Unicode-based comparison.

Read the apple documentation

your can pass your string to the another controller like this:

In guestViewController's h file :

@property (nonatomic, strong) NSString *theStringWhatYouWantToGet;

and in prepareForSegue:

controller.theStringWhatYouWantToGet  = self.num_value.text;

Add this to your guestViewController's header file :

@property (nonatomic, strong) NSString *value;

The your prepareForSegue method becomes something like this : 

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
   NSLog(@"Transferring");

   guestViewController *controller = [segue destinationViewController];
   [controller setValue : self.num_value.txt];
}

isEqualToString is for comparison! Not to be used for assigning values.

Then in your viewDidLoad method, add this :

[textLabel setText : value];
