Generating Random Image Buttons according with Random Button XCode iOS

I have 3 buttons, 1 displays the correct answer and the other two display two random incorrect answer. I also have 10 buttons, with images attached displayed.

I want to associate the images with the button output.. (i.e) if the questons is: 1 x 1, at the moment the only image output I have is the correctanswer. Not two random answers

• 
  

  Display 1 apple (imagebutton) & (correctAnswerButton)

  
  

  -Display 2 apple (display 2 imagebuttons) & (incorrectAnswerButton)

  
  


• Display 3 apple & (display 3 imagebuttons) (incorrectAnswerButton)

From the code I have already is there anyway to link both? Thanks (code below)

 NSString *levelString = [NSString stringWithFormat: @"%i", level];
    NSString *multipleString = [NSString stringWithFormat: @"%i", _levelStep];

//The levelString loads image file 


  NSString *imageName = [NSString stringWithFormat: @"%@.jpg", levelString];
    UIImage *levelImage = [UIImage imageNamed:imageName];
    [currentLevel setImage:levelImage forState:UIControlStateNormal];

//if levelstep is (1 x number) load appropriate levelImage and show multipliers

   if (_levelStep == 1) {
        [multiplier10 setImage:levelImage forState:UIControlStateNormal];
        multiplier10.hidden = NO;

        [ans1button1 setImage:levelImage forState:UIControlStateNormal];
        ans1button1.hidden = NO;

        [ans2button1 setImage:levelImage forState:UIControlStateNormal];
        ans2button1.hidden = NO;

        [ans3button1 setImage:levelImage forState:UIControlStateNormal];
        ans3button1.hidden = NO;

//Through 'til ans1button10,ans2button10,ans3button10 etc...

 int rightAnswer = level * _levelStep;
    int randomNumber = arc4random_uniform(30);
    int randomNumber2 = arc4random_uniform(30);

    //Answer Button


 [AnswerButton setTitle: [NSString stringWithFormat:@"%i", ((int)rightAnswer)] forState:UIControlStateNormal];
    [AnswerButton addTarget:self action:@selector(Change:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:AnswerButton];

  [randomButton setTitle: [NSString stringWithFormat:@"%i", ((int)randomNumber)] forState:UIControlStateNormal];
    [randomButton addTarget:self action:@selector(Change:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:randomButton];

    //Same method for random answer 2.. 

Please help me find a solution to this annoying problem!! :(
