How to Add Text Box On Top of Camera Layer in Swift?

I'm building an app that implements barcode scanning functionality using RSBarcodes. I have the camera layer configured (standard view controller with custom class) and it's working properly. However, I want to have a text box that allows the user to input a barcode manually. When I add a textbox in the storyboard, it does not show up during a test. How do I get it to appear over the camera layer, if this is even possible?

Here is the VC class.

Solution

  • Try outlet your control to the view controller and in viewDidAppear: bring it to front.

    @property (nonatomic, weak) IBOutlet UIView *your_control;

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    [self.view bringSubviewToFront:your_control];
}
