Question

我是App Development的新手，对不起，如果我问愚蠢的问题:( 我正在开发一个测验应用程序。每当我给出正确或错误的答案时，图像会出现正确或错误的答案结果，但是它会停留几秒钟，但在此之后 - 它不会继续下一个问题。它只是用按钮显示我的背景图像。当结果图像消失时，如何设置代码，直接转到新问题。我将非常感谢你的帮助。

我只想在结果图像关闭后，测验继续下一个问题。

这是我在Game.m文件中设置的代码。

-(void)RightAnswer{

    ScoreNumber = ScoreNumber + 1;
    Score.text = [NSString stringWithFormat:@"%i", ScoreNumber];
    Answer1.hidden = YES;
    Answer2.hidden = YES;
    Answer3.hidden = YES;
    CategorySelected.hidden = NO;
    Next.hidden = NO;
    imageQuestion.hidden = YES;
    Results.hidden = NO;
    Results.image = [UIImage imageNamed:@"right.png"]; [self performSelector:@selector(Results) withObject:nil afterDelay:2.0];
    GameInProgress = YES;



}

-(void)WrongAnswer{

    LivesNumber = LivesNumber - 1;
    Lives.text = [NSString stringWithFormat:@"%i", LivesNumber];
    Answer1.hidden = YES;
    Answer2.hidden = YES;
    Answer3.hidden = YES;
    imageQuestion.hidden = YES;
    CategorySelected.hidden = NO;
    Next.hidden = NO;
    Results.hidden = NO;
    Results.image = [UIImage imageNamed:@"wrong.png"];[self performSelector:@selector(Results) withObject:nil afterDelay:2.0];
    GameInProgress = YES;


    if(LivesNumber ==0) {
    Results.image = [UIImage imageNamed:@"gameover.png"];
    GameInProgress = NO;
    Exit.hidden = NO;

    }

Answer 1

我可能在这里错了，但我认为你需要一个if to the else。但我可能是错的。

if(LivesNumber ==0) {
    Results.image = [UIImage imageNamed:@"gameover.png"];
    GameInProgress = NO;
    Exit.hidden = NO;

}else{
    donextcard();    
}

如果您想知道如何制作该功能，我们需要查看更多代码。

Answer 2

-(void)Results{ // just change formate of answer.

    Results.hidden = YES;
}

-(IBAction)Answer1: (id) sender{

    if (Answer1Correct ==YES) {

        [self RightAnswer];

    }else{
        [self WrongAnswer];
    }
}

-(IBAction)Answer2: (id) sender{
    if (Answer2Correct ==YES) {
        [self RightAnswer];

    }
    else{
        [self WrongAnswer];

    }
}
-(IBAction)Answer3: (id) sender{
    if (Answer3Correct ==YES) {

        [self RightAnswer];

    }
    else{
        [self WrongAnswer];
    }
}

Answer 3

-(void)RightAnswer{

ScoreNumber = ScoreNumber + 1;
Score.text = [NSString stringWithFormat:@"%i", ScoreNumber];
Answer1.hidden = YES;
Answer2.hidden = YES;
Answer3.hidden = YES;
Answer1Correct ==YES;
CategorySelected.hidden = NO;
Next.hidden = NO;
imageQuestion.hidden = YES;
Results.hidden = NO;
Results.image = [UIImage imageNamed:@"right.png"]; [self performSelector:@selector(Results) withObject:nil afterDelay:2.0];
GameInProgress = YES;



 }

我认为问题是你永远不会将Answer1Correct设置为任何东西。所以如果你将Answer1Correct == YES添加到正确的答案方法并且Answer1Correct == NO添加到错误的方法那么它应该工作
