objective-c - 在 SpriteKit 中使用 SKLabelNode 插入换行符

Question

关于如何在 SpriteKit 中使用 SKLabelNode 类插入换行符的简单问题。我有以下代码，但它不起作用 -

 SKLabelNode *nerdText = [SKLabelNode labelNodeWithFontNamed:@"Times"];
    NSString *st1 = @"Test break";
    NSString *st2 = @"I want it to break";
    NSString *test = [NSString stringWithFormat:@"%@,\r%@",st1,st2]; //Even tried \n
    nerdText.text = test;
    nerdText.fontSize = 11;
    nerdText.fontColor = [SKColor colorWithRed:0.15 green:0.15 blue:0.3 alpha:1.0];
    nerdText.position = CGPointMake(150.0, 250.0);
    [self addChild:nerdText];

请帮帮我!

我不认为你可以，这里有一个“hack”的方式来做到这一点

SKNode *nerdText = [SKNode node]; 
SKLabelNode *a = [SKLabelNode labelNodeWithFontNamed:@"Arial"];
a.fontSize = 16;
a.fontColor = [SKColor yellowColor];
SKLabelNode *b = [SKLabelNode labelNodeWithFontNamed:@"Arial"];
b.fontSize = 16;
b.fontColor = [SKColor yellowColor];
NSString *st1 = @"Line 1";
NSString *st2 = @"Line 2";
b.position = CGPointMake(b.position.x, b.position.y - 20);
a.text = st1;
b.text = st2;
[nerdText addChild:a];
[nerdText addChild:b];
nerdText.position = CGPointMake(150.0, 250.0);
[self addChild:nerdText];
