ios - 分数标签显示值覆盖

Question

当乐谱更新时，新的乐谱值标签会覆盖显示的旧乐谱，因为这个乐谱是不可读的，如何更新新的乐谱？这是我得到的:

SKLabelNode *ScoreLabel;
NSInteger score = 0;
-----------------------------
-(void)Scoring{
score = score +1;
ScoreLabel = [SKLabelNode labelNodeWithFontNamed:@"Arial"];
ScoreLabel.position = CGPointMake(CGRectGetMidX(self.frame), 960);
ScoreLabel.text = [NSString stringWithFormat:@"%ld",(long)score];
[self addChild:ScoreLabel];
}

Answer 1

每次乐谱更改时，您都会在顶部添加一个新标签。像这样更改代码:

-(void)Scoring{
  score = score +1;
  if (ScoreLabel == nil) {
    ScoreLabel = [SKLabelNode labelNodeWithFontNamed:@"Arial"];
    ScoreLabel.position = CGPointMake(CGRectGetMidX(self.frame), 960);
    [self addChild:ScoreLabel];
  }
  ScoreLabel.text = [NSString stringWithFormat:@"%ld",(long)score];

}
