Hide programmatically created UIButton for tag

I currently have 14 buttons that are created programmatically using a for loop, the code below:

int buttonCount = 14;
for (int i=0; i< buttonCount; i++) {             

//Create titleString from array object
    NSString *stringFromInt = [NSString stringWithFormat:@"%@",[arrayForRound objectAtIndex:i]];


        UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

        [button addTarget:self
                   action:@selector(buttonSelected:)
         forControlEvents:UIControlEventTouchDown];

        [button setTitle:stringFromInt forState:UIControlStateNormal];

        button.titleLabel.font = [UIFont fontWithName:@"helvetica" size:19];
        button.tag = i;

        [self.view addSubview:button];
}

This works great for creating buttons, after which I can fill out the answer block with the value of the selected button:

-(void)buttonSelected: (UIButton *)sender
{
[_buttonOne setTitle:sender.titleLabel.text forState:UIControlStateNormal];
}

However, after the button was full, I would like to remove it from the screen. If I call button.hidden, it just hides the last button that was programmed by the program. I know button.tag and try to use this, but it seems to me that I almost need to do something like:

//Hide button for tag (i know this is incorrect syntax)
button for buttonTag: 3 setHidden;

Is there something similar or a way to do this?

You can get an idea by tag using this post.

[self.view viewWithTag:3];

We always set a tag with a macro just like

#define kFirstButtonTag (100)

or use

#define kButtonBeginTag (100)

Then use the macro to get the tag.

And in a special number - Case 0, 1 or 2 is always used, start your tag in a special amount to avoid some problems.
