Question

我有一个游戏，其中火球UIImage从屏幕上掉落，并且用户使用触摸屏移动玩家对象以避免它们。 8点之后，playAgainButton弹出。但是，这个playAgainButton按钮不起作用。它不会执行ResetGame方法中的任何代码，它实际上会重置我的角色对象“Dustin”的位置，我不想发生这种情况。我有一个连接到按钮的引用插座。如何让ResetGame中的代码生效？我的ViewController代码如下所示。

 int theScore;

- (void)viewDidLoad {
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.
    [self initializeTimer];
}

- (IBAction)ResetGame:(id)sender {  //only thing that actually happens right now is that Dustin resets for some reason.
    theScore = 0;

    [self updateScore];

    _Fireball.center = CGPointMake(64, 64);
    _endLabel.hidden = true;
    _playAgainButton.hidden = true;

    [self gameLogic:theTimer];
}

- (void)updateScore {
    _score.text = [[NSString alloc] initWithFormat:@"%d",theScore];
}

- (void) initializeTimer {
    if(theTimer == nil)
    {
        theTimer = [CADisplayLink displayLinkWithTarget:self selector:@selector(gameLogic:)];
    }

    theTimer.frameInterval = 1;
    [theTimer addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
}

- (void) gameLogic:(CADisplayLink *) theTimer {
    if((!CGRectIntersectsRect(_Fireball.frame, _Dustin.frame)) && (theScore < 8)){
        if(_Fireball.center.y >600){
            int num = arc4random() % 3;
            if(num == 0){
                _Fireball.center = CGPointMake(64, 64);
            }
            else if(num == 1){
                _Fireball.center = CGPointMake(192, 64);
            }
            else if(num == 2){
                _Fireball.center = CGPointMake(320, 64);
            }

            theScore = theScore + 1;
            [self updateScore];
            }

          _Fireball.center = CGPointMake(_Fireball.center.x, _Fireball.center.y+12);    }
    else if(theScore == 8){
        _Fireball.center = CGPointMake(_Fireball.center.x, _Fireball.center.y);

        _endLabel.text = @"You Win!";
        _endLabel.hidden = false;
        _playAgainButton.hidden = false;
    }
}

- (void) touchesBegan:(NSSet *) touches withEvent:(UIEvent *) event {
    UITouch *touch = [touches anyObject];

    _firstTouch = [touch locationInView:self.view];
    _lastTouch = [touch locationInView:self.view];

    _Dustin.center = CGPointMake(_firstTouch.x, _Dustin.center.y);
}

-(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch *touch = [touches anyObject];

    _firstTouch = [touch locationInView:self.view];
    _lastTouch = [touch locationInView:self.view];

    _Dustin.center = CGPointMake(_firstTouch.x, _Dustin.center.y);
}

-(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch *touch = [touches anyObject];

    _firstTouch = [touch locationInView:self.view];
    _lastTouch = [touch locationInView:self.view];

    _Dustin.center = CGPointMake(_firstTouch.x, _Dustin.center.y);
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.
}

你的touchesBegan等方法并没有调用超级方式，因此你的应用程序正在捕获所有触摸，无法通过你的按钮。

为每个方法添加对super的调用。
