iOS转换语句不起作用

Question

我正在开发iOS应用程序时出现问题：我在两个屏幕中使用了switch语句来处理多个问题的回复，但它们似乎无法正常工作：也许我犯了一些错误，但是由于我还在学习iOS，我不确定它是什么。

以下是这些屏幕的代码：

Riddle.m

#import "Riddle.h"

@interface Riddle()

@end

@implementation Riddle

int reply;

-(void) viewDidLoad
{

    _etiqueta = @" 1: Que es allò blanc que tenia Santiago?";
    self.label.text = self.etiqueta;

    _eti = @"";
    self.lab.text = self.eti;

    [super viewDidLoad];

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self
            action:@selector(dismissKeyboard)];

    [self.view addGestureRecognizer:tap];

}

-(void)dismissKeyboard {
    [_resposta resignFirstResponder];
}

-(IBAction) buttonPressed: (id) sender
{
    switch (reply)
    {
        case 1:
        {
            _resposta.text = @"cavall";
            _eti = @"Correcte!";
            _resposta.text = @"";
            self.lab.text = self.eti;
            _etiqueta = @" 2: Què portes als peus?";
            self.label.text = self.etiqueta;
            break;
        }

        case 2:
        {
            _resposta.text = @"sabates";
            _eti = @"Correcte!";
            _resposta.text = @"";
            self.lab.text = self.eti;
            _etiqueta = @" 3: Què tires en l'oca?";
            break;
        }

        case 3:
        {
            _resposta.text = @"daus";
            _eti = @"Correcte!";
            _resposta.text = @"";
            self.lab.text = self.eti;
            _etiqueta = @" 4: Amb què ve l'hamburguesa?";
            break;
        }

        case 4:
        {
            _resposta.text = @"patates";
            _eti = @"Correcte!";
            _resposta.text = @"";
            self.lab.text = self.eti;
            _etiqueta = @" 5: Què té el pegàs?";
            self.label.text = self.etiqueta;
            break;
        }

        case 5:
        {
            _resposta.text = @"ales";
            _eti = @"Correcte! Les has encertades totes!";
            self.lab.text = self.eti;
            break;
        }

        default:
        {
            _eti = @"Incorrecte!";
            _resposta.text = @"";
            self.lab.text = self.eti;
            break;
        }

    }

}
