Believe or not, there several duplicates with **the exact same title.** I can't imagine you couldn't have found at least one of them if you had actually used Google or the site search. — , Oct 19 '13 at 19:44
Also, this has nothing to do with Xcode -- this is a language/algorithm/API question, and it wouldn't be different if you used `make` and `emacs` for writing your iOS application. — , Oct 19 '13 at 19:45
possible duplicate of [passing data between view controllers iOS](http://stackoverflow.com/questions/17536760/passing-data-between-view-controllers-ios) and [Passing Data between View Controllers](http://stackoverflow.com/questions/5210535/passing-data-between-view-controllers) — , Oct 19 '13 at 19:45
@H2CO3 - Wouldn't be that different if you were writing in C++ or C#, for that matter. — Hot Licks, Oct 19 '13 at 21:12
@HotLicks This would only be related to Xcode if the question was "how to do it in Interface Builder instead of by writing code" IMO. — , Oct 19 '13 at 21:13

In story Board you can send value one view to another view like Bellow way. Your Implement method did Wrong.

in you Second view-controller you need to define NSString with property and sythsize it.

.h class

@property (nonatomic, strong) NSString *YourString;

.m Class

@synthesize YourString;

Now you can use it like:-

-(IBAction)youMethod:(id)sender
{
    [self performSegueWithIdentifier:@"secondview" sender:self];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
            if ([segue.identifier isEqualToString:@"secondview"]) {
         secondviewcontroller *controller = segue.destinationViewController
                controller.YourString = @"myValue";
             }

}
