    text
    copied!<p>What's wrong with the following code? Xcode 4 is saying that the two method declarations with "Question" don't compile due to an '"expected ")" before "Question"; message, as indicated in the comments in the code below. The Question class compiles and this code has been working previously. I made some changes to Questions, but backed them out to try to figure out this compile time error. </p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "Question.h" @interface AppState : NSObject { int chosenAnswer; int correctAnswers; int currentQuestionNumber; // this will contain the hash table of question objects NSMutableDictionary *questionHash; } @property (nonatomic) int chosenAnswer; @property (nonatomic) int correctAnswers; @property (nonatomic) int currentQuestionNumber; @property (nonatomic, retain) NSDictionary *questionHash; - (void) printQuestions; - (void) printDescription; - (void) addQuestion: (Question *) question; // &lt;==== error - (int) numberOfQuestions; - (void) saveState; - (void) resetState; - (Question *) currentQuestion; // &lt;===== error @end </code></pre> <p>Here's Question.h:</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "AppState.h" @interface Question : NSObject { NSString *questionTxt; int correctAnswer; int number; // this will contain the hash table of questions_answer objects NSMutableDictionary *answerHash; } @property (nonatomic, retain) NSString * questionTxt; @property (nonatomic) int correctAnswer; @property (nonatomic) int number; @property (nonatomic, retain) NSMutableDictionary *answerHash; -(void) addAnswer: (NSString *) answer; - (NSMutableArray *) answerArray; - (void) printDescription; - (void) printAnswers; - (NSString *) correctAnswerText; - (Question *) currentQuestion; @end </code></pre>
