Change UILabel text

I am fairly new to objective-C and XCode. I am trying to update a text label on the screen,

I call a function loadData in viewDidLoad, which works fine. I am trying to print a string that was generated in the loadData function. After that string is generated, I use:

self.MyLabel.text=string;

But does not update. I am using IBOutlet as well, I think it might be related to different threads but I am not sure.

Any help is appreciated.

Have you tried updating the label after the 

- (void)viewDidLoad {
   // call another method before assigning to retrieve the string here.
   self.MyLabel.text=string;
}

Sometimes the way the UIViewController and IB setup will need you to set in after the viewDidLoad. Try NSLog(@"%@", self.MyLabel) at wherever you try to assign to see if its not null

Your statement is correct:

self.mylabel.text = @"Test";

So make sure, that the IBOutlet is correctly connected (filled grey circle).

Check also if the string contains the correct value.
