try below code

 -(void)viewWillAppear:(BOOL)animated
    {
       NSString *checkFb=[[NSUserDefaults standardUserDefaults] valueForKey:@"someKey"];
       if(checkFb.lenght > 0)
       { 

        testLabel.text=checkFb;
        }

    }


   -(void)changeData{

      testLabel.text=@"changed data";
    [[NSUserDefaults standardUserDefaults] setObject: testLabel.text forKey:@"someKey"];
    [[NSUserDefaults standardUserDefaults] synchronize];


   }

Just Take the Global Variable Declare it in App Delegate and assign your label value to this global variable your problem will be solve.

Still if you dont get it feel free to ask me its so simple buddy
