如何在测验中实现几个答案？

Question

我创建了一个有4个答案的测验，其中一个是正确答案。问题和答案我保留在plist。（其中有字典数组）。 现在我想对一个问题有一个以上的正确答案。示例：用户可以选择A B C D或A C或B C D等，然后按“下一个问题”按钮。 请告诉我实现我的使命的正确方法！

对不起我的ENG，我是俄罗斯人。

enter code here- (void)showNextQuestion
    {
if ([self.highScore integerForKey:@"HighScore"]<numCorrect){
    [self.highScore setInteger:numCorrect forKey:@"HighScore"];
    [self.highScore synchronize]; 
}

currentQuestion++; //= arc4random()%10;
if (currentQuestion <= [self.questions count]){

    self.labelScore.text = [NSString stringWithFormat:@"%d", numCorrect];
    self.labelHighestScore.text = [NSString stringWithFormat:@"%d", [self.highScore integerForKey:@"HighScore"]];

    NSDictionary* nextQuestion = [self.questions objectAtIndex: currentQuestion];//[self.questions objectForKey:[NSString stringWithFormat:@"%d", currentQuestion]];
    NSString* correctAnswer = [nextQuestion objectForKey:@"CorrectAnswer"];
    self.answer = correctAnswer;

    self.labelA.text = [nextQuestion objectForKey:@"A"];
    self.labelB.text = [nextQuestion objectForKey:@"B"];
    self.labelC.text = [nextQuestion objectForKey:@"C"];
    self.labelD.text = [nextQuestion objectForKey:@"D"];


    self.labelQuestion.text = [nextQuestion objectForKey:@"QuestionTitle"];
    NSLog(@"%d количество вопросов", countQuestion);

    int questNumber = countQuestion+1;

            NSString *questNumberString = [[NSString alloc] initWithFormat:@"%d",                 questNumber];
    NSLog(@"%@", questNumberString);

    questNum.text = questNumberString;


    - (IBAction)buttonPressedA:(id)sender {
  //AudioServicesPlaySystemSound(SoundID1);
   countQuestion++;
        if([self.answer isEqualToString: @"A" ]){
    numCorrect += 1;

    self.labelScore.text = [NSString stringWithFormat:@"%d", numCorrect];
        }
        [self showNextQuestion];
    }

    - (IBAction)buttonPressedB:(id)sender {
 // AudioServicesPlaySystemSound(SoundID1);
 countQuestion++;
if([self.answer isEqualToString: @"B"]){
    numCorrect += 1;

    self.labelScore.text = [NSString stringWithFormat:@"%d", numCorrect];
        }

        [self showNextQuestion];}

在你的plist里面，把答案本身变成一本字典。使用一个键/值对作为标题，另一个用于指示它是否正确。

当用户选择答案时，您只需检查相应的布尔值（在本例中为“正确”）。
