Like a lot of others I also needed a fix to this problem. My approach was a lot simpler than Chris' solution. I have made a subclass of SKLabelNode called NORLabelNode.

It's available at GitHub and there is also a cocoapod available.

It simply creates a set of SKLabelNodes and use these as subnodes. If you want to implement something similar yourself the main gist is this method:

- (NSArray *)labelNodesFromText:(NSString *)text{
    NSArray *substrings    = [text componentsSeparatedByString:@"\n"];
    NSMutableArray *labelNodes    = [[NSMutableArray alloc] initWithCapacity:[substrings count]];

    NSUInteger labelNumber    = 0;
    for (NSString *substring in substrings) {
        SKLabelNode *labelNode    = [SKLabelNode labelNodeWithFontNamed:self.fontName];
        labelNode.text    = substring;
        labelNode.fontColor    = self.fontColor;
        labelNode.fontSize    = self.fontSize;
        labelNode.horizontalAlignmentMode    = self.horizontalAlignmentMode;
        labelNode.verticalAlignmentMode    = self.verticalAlignmentMode;
        CGFloat y    = self.position.y - (labelNumber * self.fontSize * self.lineSpacing);
        labelNode.position    = CGPointMake(self.position.x, y);
        labelNumber++;
        [labelNodes addObject:labelNode];
    }

    return [labelNodes copy];
}

The above is somewhat simplified as the labels also inherit most of the other properties from their parent.

The linespacing can be altered through a CGFloat property. Apart from this is works just like an ordinary SKLabelNode and you can change text, color, font, fontSize etc. on the fly whenever you feel like.
