Can anyone help me that how could I access it?

Solution
Go into your Storyboard file, right-click on the offending control, and make sure that you have a variable name shown under "Referencing Outlets".
If it's not... the control isn't bound to a variable, and that'd explain your nil.
You can also go into your .h file, and check that your IBOutlets all have filled in circles to the left of them. This also tells you that they are bound to a control.
