iphone – 如何在Cocos2d中更新和显示分数整数？

在.h文件中：

@interface HelloWorld : CCLayer {
    int score;    
    CCLabelTTF *scoreLabel;
}

- (void)addPoint;

在.m文件中：

//Set the score to zero.
score = 0;

//Create and add the score label as a child.
scoreLabel = [CCLabelTTF labelWithString:@"8" fontName:@"Marker Felt" fontSize:24];
scoreLabel.position = ccp(240,160); //Middle of the screen...
[self addChild:scoreLabel z:1];

别的地方：

- (void)addPoint
{
    score = score + 1; //I think: score++; will also work.
    [scoreLabel setString:[NSString StringWithFormat:@"%@",score]];
}

现在只需致电：[self addPoint];每当用户杀死敌人时.

这应该工作,告诉我,如果没有,因为我没有测试它.
