如何更改SKLabelNode的文本? [英] How to change text of a SKLabelNode?

问题描述

如何更新在initWithSize中创建的标签文本? 这是initWithSize中标签的代码:

How do I update a label's text that was created in initWithSize? Here is the code for the label within the initWithSize:

SKLabelNode *scoreLabel = [SKLabelNode labelNodeWithFontNamed:@"TimesNewRoman"];
    scoreLabel.text = [NSString stringWithFormat:@"%i", score];
    scoreLabel.fontSize = 30;
    scoreLabel.position = CGPointMake(290, CGRectGetMidY(self.frame) - 30);
    scoreLabel.zRotation = -M_PI/2;
    [self addChild:scoreLabel];

在游戏运行时，我会更新变量分数，而我只是想知道如何获取标签来显示新分数.

As the game is running I update the variable score and I was just wondering how I can get the label to display the new score.

推荐答案

您将不得不在头文件中声明scoreLabel，然后在所需的任何位置声明scoreLabel.text = //Your text.

You will have to declare scoreLabel in the header file and then just so scoreLabel.text = //Your text anywhere you want.

在您的.h文件中，声明 @property (nonatomic,strong) SKLabelNode *scoreLabel;

In your .h file, declare @property (nonatomic,strong) SKLabelNode *scoreLabel;

在您的.m文件中，添加 @synthesize scoreLabel;

In your .m file, add @synthesize scoreLabel;

初始化标签时

self.scoreLabel = [SKLabelNode labelNodeWithFontNamed:@"TimesNewRoman"];

不是

SKLabelNode *scoreLabel = [SKLabelNode labelNodeWithFontNamed:@"TimesNewRoman"];
