I think you need to pass one variable data into another view controller.

viewController.m

 -(void)viewWillDisappear {

     //pass value to secondViewController
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; // use your storyboard name
    secondviewcontroller *vc = [storyboard instantiateViewControllerWithIdentifier:@"secondviewcontroller"];

      vc.value2 = @"String here"; 
 }

secondViewController.h

 @property (nonatomic, retain) NSString *value2;

secondViewController.m

 @implementation coachViewController
 @synthesize value2;
-(IBAction)buttonPressed {

    self.label.text = value2; //Declare value2 in .h file 
}

viewController.m

-(void)viewWillDisappear {

     //pass value to secondViewController
    secondViewController *vc=[[secondviewcontroller alloc]init];
    vc.headStr=@"your string"; //same for array and dictionary
    //Push code.........
 }

//secondViewController.h

@property (strong, nonatomic) NSString *headStr;


secondViewController.m

-(void)ViewDidLoad
{
[super:ViewDidLoad];
Nslog("%@",self.headStr);
}
