How to show / hide UIView when clicking a button in iOS

Question

I have UIViewadded to my xib file. Connect the inspector correctly.

In the viewDidLoad:method, I hide it and on some pressed button, showing it.

Here is my code:

.h file

@property (nonatomic, retain) IBOutlet UIView   *subView;

in viewDidLoad::

_subView.hidden = YES;

Hides this view correctly, but when you click a button, it does not appear.

- (IBAction)customerInvoice:(id)sender
{
//self->_subView.hidden = NO;
_subView.hidden = NO;
}

Using both methods, it does not appear. Please help me solve the problem.
