Setting UILabel text from rootViewController

Question

I have two view controllers 1.rootviewController 2.myStatusDisplayViewController.

I have c stack call back function which returns ac string.That particular call back function calls a function in my rootviewcontroller. In my rootview controller I have reference to myStatusDispalyViewController using that reference I'm trying to update the label in myStatusDisplayviewController.

app.myStatusDisplayViewController.displayCallStatus.text =updatedCallStatus;
[app.myStatusDisplayViewController viewDidLoad];
[app.myStatusDisplayViewController viewWillAppear:YES];

Answer 1

Set your text in that block:

  dispatch_async(dispatch_get_main_queue(), ^{
     app.myStatusDisplayViewController.displayCallStatus.text =updatedCallStatus;
        });

Hope it will work.
