分数标签显示值覆盖

Question

当分数更新时，新的分数值标签会覆盖显示屏上的旧分数值，因为此分数只是无法读取，所以如何更新新分数？这里我得到了什么：

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

你每增加一个新的标签在顶部添加分数。更改代码是这样的：

-(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]; 

}
