真的很难搞清楚这一点.只是试图从PHP中获取数据
curRow = [[NSMutableArray alloc]init];
[curRow addObject:[JSON valueForKeyPath:@"question"]];
[curRow addObject:[JSON valueForKeyPath:@"answers"]];
[curRow addObject:[JSON valueForKeyPath:@"correct_answer"]];
[gameQuestions addObject:curRow];
在另一种方法中,我这样做
int i = arc4random() % [gameQuestions count];
CCLOG(@"Random: %i", i);
currentQuestion = [[gameQuestions objectAtIndex:i]objectAtIndex:0];
currentAnswer = [[gameQuestions objectAtIndex:i]objectAtIndex:1];
currentCorrectAnswer = [[gameQuestions objectAtIndex:i]objectAtIndex:2];
CCLOG(@"question: %@", currentQuestion);
CCLOG(@"answer: %@", currentAnswer);
但是当我查看调试日志时,我的问题和答案是同一个对象？
