本文介绍了如何在Swift中使用Chalkduster字体创建SKLabelNode，并详细说明了如何设置其属性如字体大小、颜色、混合模式等。通过实例演示，帮助开发者更好地理解和应用SpriteKit中的文本渲染功能。

        SKLabelNode *helloNode = [SKLabelNode labelNodeWithFontNamed:@"Chalkduster"];
        helloNode.name = @"helloNode";
        helloNode.text = @"Hello, World!";
        helloNode.fontSize = 24;
        helloNode.fontName = @"Chalkduster";
        helloNode.fontColor = [SKColor blackColor];
        helloNode.colorBlendFactor = 0.3;//颜色混合 这个值必须在0.0到1.0之间。默认值为0.0
        helloNode.blendMode = SKBlendModeReplace;//混合节点
        helloNode.position = CGPointMake(CGRectGetMidX(self.frame),CGRectGetMidY(self.frame));
        [self addChild:helloNode];

blendMode:节点混合模式

typedef NS_ENUM(NSInteger,SKBlendMode){
SKBlendModeAlpha = 0,
SKBlendModeAdd = 1,
SKBlendModeSubtract = 2,
SKBlendModeMultiply = 3,
SKBlendModeMultiplyX2 = 4,
SKBlendModeScreen = 5,
SKBlendModeReplace = 6,
}

SKBlendModeAlpha 源颜色乘以alpha值
SKBlendModeAdd 源颜色和目标颜色相加
SKBlendModeSubtract 目标颜色减去源颜色
SKBlendModeMultiply 源颜色乘以目标颜色
SKBlendModeMultiplyX2 源颜色乘以目标颜色乘以2
SKBlendModeScreen 源颜色乘以目标颜色乘以倒源色
SKBlendModeReplace 源颜色替换目标颜色
