Question

我在下面的这段文字太长了，无法在屏幕上运行。我如何制作这2行而不是1行？

myLabel.text = "The weather today is going to be partly cloudy with a chance of rain"

Answer 1

您可以创建自己的方法来显示多行文字，如下所示：

import SpriteKit

class GameScene: SKScene {
    override func didMoveToView(view: SKView) {
        displayMultiLineTextAt(CGRectGetMidX(self.frame) - 100, y: CGRectGetMidY(self.frame) + 50, align: SKLabelHorizontalAlignmentMode.Left, lineHeight: 20.0, text: "Welcome to StackOverFlow!\nThe weather today is going to\nbe partly cloudy with a chance\nof rain.")
    }
    func displayMultiLineTextAt(x: CGFloat, y: CGFloat, align: SKLabelHorizontalAlignmentMode, lineHeight: CGFloat, text: String) {
        let textNode = SKNode()
        textNode.position = CGPointMake(x, y)
        var lineAt: CGFloat = 0
        for line in text.componentsSeparatedByString("\n") {
            let labelNode = SKLabelNode(fontNamed: "Arial")
            labelNode.fontSize = 14
            labelNode.horizontalAlignmentMode = align
            labelNode.fontColor = SKColor(hue: 1, saturation: 1, brightness: 1, alpha: 1)
            labelNode.position = CGPointMake(0, lineAt)
            labelNode.text = line
            textNode.addChild(labelNode)
            lineAt -= lineHeight
        }
        scene!.addChild(textNode)
    }
    override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
        /* Called when a touch begins */
    }
    override func update(currentTime: CFTimeInterval) {
        /* Called before each frame is rendered */
    }
}

<强>＃1
设置行数：

/web

<强>＃2
使用myLabel.numberOfLines = 2 //set to 0 if you want it to automatically decide based on how many line breaks you add in step 2或\n

在文字中添加换行符

修改

您应该澄清您使用的是myLabel.text = "The weather today is going to\nbe partly cloudy with a chance of rain"而不是正常SKLabelNode。以下是您可以执行的操作，因为UILabel不支持多行。

创建新视图

将标签＃1添加到视图

在视图中添加另一个标签（＃2），将其放在标签＃1
下面
将句子分成两部分，将第一部分添加到标签＃1，第二部分添加到标签＃2

Answer 3

myLabel.numberOfLines = 2 //或设置为0
确保myLabel.frame.size.height足够

如何使一个标签节点的文本占用2行？
