removeFromSuperview can't reopen - ios

Question

I have a button (Buy) to open up a UIView (viewInAppPurchases) on top of another UIView (viewMenu). The Buy button is in the UIView viewMenu. I also have a button (Close) in the UIView viewInAppPurchases.
In the code when clicking the close button in the viewInAppPurchases, it shall close the view and go back to the viewMenu. But when clicking on the Buy button again, nothing happens. It should reopen the viewInAppPurchases UIView.
What else should I add and/or change to the code so when the Buy button is clicked again, it shall open up the viewInAppPurchases again?
In Header file:
#property (strong, nonatomic) IBOutlet UIView *viewInAppPurchases;
In implementation .m file:
- (IBAction)buttonClose: (UIButton*)sender
{
[_viewInAppPurchases removeFromSuperview];
}
Below is the IAP as GaryRiches request. I noticed that I didn't have a "close button" instruction in the IAP itself, but only through the MenuViewController.
How do I put the close button instructions in it?

Answer 1

What else should I add and/or change to the code so when the Buy
button is clicked again, it shall open up the viewInAppPurchases
again?
You should add it back to the view from which you removed it.
You can do it on click event by:
[self.view addSubview: _viewInAppPurchases];
Also, have you consider hiding it instead of removing it completly and then adding it back?
To hide your view:
[_viewInAppPurchases setHidden:YES];
To show it again:
[_viewInAppPurchases setHidden:NO];

Answer 2

I changed the
removeFromSuperview
to
setHidden:Yes
and it did the trick.
