Question

嗨我正在使用Xcode作为应用程序，我的评分系统每秒上升1点。如何让它从25开始，然后以每秒1点的速度上升。这是代码：

-(void)Scoring{

ScoreNumber = ScoreNumber + 1;
Score.text = [NSString stringWithFormat:@"Score: %i", ScoreNumber];



-(void)NewGame{

ScoreNumber = 0;
Score.text = [NSString stringWithFormat:@"Score: 0"];

请帮助!!

Answer 1

在NewGame中，您将ScoreNumber设置为0.将其设置为25而不是：

-(void)NewGame{

ScoreNumber = 25;
Score.text = [NSString stringWithFormat:@"Score: 25"];

Answer 2

试试这个：

- (void) newGameWithStartingScore:(int)startingScore {

    // Set our label
    Score.text = [NSString stringWithFormat:@"Score: %i", startingScore];
    // Store our score in our dictionary
    NSDictionary * userInfo = [@{@"currentScore" : @(startingScore)} mutableCopy];
    // Start the timer
    [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(incrementScore:) userInfo:userInfo repeats:YES];
}

-(void)incrementScore:(NSTimer *)timer {

    // Get current score
    int currentScore = [timer.userInfo[@"currentScore"] intValue];
    // Increment it
    currentScore++;
    // Update userInfo ref
    timer.userInfo[@"currentScore"] = @(currentScore);

    // Set our label
    Score.text = [NSString stringWithFormat:@"Score: %i", currentScore];

    // See if timer should continue
    BOOL shouldInvalidate = NO;
    /*
     Insert validation logic here.  Set 'shouldInvalidate' to YES in order to stop the timer
     */
    if (shouldInvalidate) {
        [timer invalidate];
    }

}

假设Score是对标签的引用，或者可以显示文本的内容，您可以这样称呼它：

[self newGameWithStartingScore:25];

这样，您可以根据需要进行修改。

我希望我的评分系统从一定数量开始
