如何在測驗中實現幾個答案？

Question

我用4個答案創建了一個測驗，其中一個答案是正確答案。問題和答案我保持plist。（它有字典數組）。 現在我想對一個問題有多個正確的答案。例如：用戶可以選擇A B C D或A C或B C D等，然後按下「下一個問題」按鈕。 請告訴我實現我的使命的正確方法！

對不起，我是ENG，我是俄羅斯人。

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;

裏面你的plist，使答案本身的字典。標題使用一個鍵/值對，另一個用於指示它是否正確。

當用戶選擇一個答案，你只需要檢查相應的布爾值（在這種情況下，「正確」）。
