Xcode hiding buttons

Question

I'm curious to know is there a way to edit what happens at a app startup to hide buttons? I can hide them when the app is running but I want some buttons hidden when the app starts up and displayed later on after me touching one of my displayed buttons, is there a way to do this?

Answer 1

In code

UIView has a hidden property. You can toggle it to hide/show as you want in code, for example:

myView.hidden = YES; // YES/NO

You'll want to do this anywhere after -viewDidLoad

Interface Builder

In the inspector, once you've selected the view you want to hide, you should see something like this (look in the View > Drawing options - at the bottom).

It's the hidden property you want to check here... You'll want to make an outlet to your code so you can unhide this later on...

Answer 2

You could initially set your buttons hidden via the Attribute Inspector. There's a check box down there View -> Drawing -> Hidden to hide the button.

Then you coud to set your buttons visible in the touch action of another visible button like following:

#import "HBOSViewController.h"

@interface HBOSViewController ()
// your buttons outlets here
@property (weak, nonatomic) IBOutlet UIButton *topButton1;
@property (weak, nonatomic) IBOutlet UIButton *topButton;

@end

@implementation HBOSViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

// The action of the visible button to make your hidden button visible.
- (IBAction)showButton:(id)sender {
    if (self.topButton) {
        self.topButton.hidden=NO;
    }
    if (self.topButton1) {
        self.topButton1.hidden=NO;
    }
}

@end
