Passing data to from one controller to another view controller

Question

I want to pass value and display from ViewController1 to ViewController2, when I go to ViewController2. The data did not display on the view. But I check po data.odrNum it has the value in it.

ViewController1

ViewController2 *data = [[ViewController2 alloc] init];
data.odrNum = [respondData valueForKey:@"orderCode"];

ViewController2.h

@property (strong, nonatomic) NSString *odrNum;

ViewController2.m

self.orderConNum.text = self.odrNum;

And this is the way I present my ViewController2

 UIStoryboard * storyboard = self.storyboard;
    OrderDetailsViewController *detail = [storyboard instantiateViewControllerWithIdentifier: @ "OrderDetailsViewController"];
    [self.navigationController pushViewController:detail animated:YES];

you have to check value is comming in self.odrNum in ViewController2? — Birendra, Jun 06 '17 at 09:42
try this ViewController2 *vc2=[self.storyboard instantiateViewControllerWithIdentifier:@"ViewController2"]; vc2.odrNum = [respondData valueForKey:@"orderCode"] [self.navigationController pushViewController:vc2 animated:YES]; — Ravi Panchal, Jun 06 '17 at 09:44

@Edmund print this value of [respondData valueForKey:@"orderCode"]; before passing it — Ravi Panchal, Jun 06 '17 at 09:53
@Edmund so check in secondVC cause you are assigning a value so may be you are reassign the value in it — Ravi Panchal, Jun 06 '17 at 09:57

Pass data when you push viewcontroller .

UIStoryboard * storyboard = self.storyboard;
OrderDetailsViewController *detail = [storyboard instantiateViewControllerWithIdentifier: @ "OrderDetailsViewController"];

detail.odrNum = [respondData valueForKey:@"orderCode"];  // this line you must put when you want to pass data. 

[self.navigationController pushViewController:detail animated:YES];

not working for me – Nurburgring Jun 06 '17 at 09:54
put break point on this line detail.odrNum = [respondData valueForKey:@"orderCode"]; and check did you get any value from this [respondData valueForKey:@"orderCode"]; @Edmund – Himanshu Moradiya Jun 06 '17 at 09:55
it show nil value – Nurburgring Jun 06 '17 at 09:57
then you must have to get that value that you want to pass to next controller for testing just pass static value like detail.odrNum = @"Testing "; @Edmund and check did you get value testing on next controller. – Himanshu Moradiya Jun 06 '17 at 09:59
Yes, if I use detail.odrNum = @"Testing, VC2 will work – Nurburgring Jun 06 '17 at 10:03
@Edmund when you got your response from server at that time just store that reponse to one varible that Nssting put it global and when you want to pass data just pass that string varible so you easily send a value to next controller. hope you will clear with my answer . any problem or issue just put comment, – Himanshu Moradiya Jun 06 '17 at 10:09

Have you considered using a sharedSingleton:

In the dropbox file is the sharedSingleton files I use.

In the Changables.h file you can add the variables you want to use and you can import it on the UIViewControllers you want to use.

To set this you only have to use:

[Changables sharedSingleton].yourVariable = @"my variable data"

and to get the data back you can just use

[Changables sharedSingleton].yourVariable.

I have used this to use custom Objects as well.
