回答你的问题。 您可以调整CCCLabelTTF线路。 But! 我将同你分享我的解决方案。

就是这样。 h

#import <Foundation/Foundation.h>
#import "cocos2d.h"

@interface CCLabelTTFLineSpaced : CCLayer {
}

+ (id) labelWithString:(NSString*)string dimensions:(CGSize)dimensions alignment:(CCTextAlignment)alignment fontName:(NSString*)name fontSize:(CGFloat)size lineSpace:(CGFloat)space;

- (id) initWithString:(NSString*)str dimensions:(CGSize)dimensions alignment:(CCTextAlignment)alignment fontName:(NSString*)name fontSize:(CGFloat)size lineSpace:(CGFloat)space;

@end

这也是事实。 页: 1

    if( (self=[super init]) ) {
        anchorPoint_ = ccp(0.5f, 0.5f);
        [self setContentSize:dimensions];
        self.isRelativeAnchorPoint = NO;

        int pos = 0;
        int i = 0;
        while (pos<[str length]) {
            int end = 0;
            int lastCut = -1;
            bool finished=NO;
            while (finished==NO) {
                CGSize actualSize = [[str substringWithRange:NSMakeRange(pos, end)] sizeWithFont:[UIFont fontWithName:name size:size]];

                if (actualSize.width > dimensions.width || pos+end == [str length]) {

                    finished=YES;
                }
                else {

                    }
                    end++;
                }
              }

            NSString * strLine = [str substringWithRange:NSMakeRange(pos, lastCut)];

            CCLabelTTF * line = [CCLabelTTF labelWithString:strLine dimensions:CGSizeMake(dimensions.width, size*2) alignment:alignment fontName:name fontSize:size];

a. 便于使用; 我必须用洗衣机、 set机和所有 st子完成这一班级。 我知道,这是一个“本土”解决办法,但令人 he! 它发挥作用!

对于有2d 2.x的可可公司,我修改了@Hardschool法,以固定假造方法,并努力工作!

感谢@Hardschool!

gmoegas, 这里称为“Color”

void CCLabelTTFLineSpaced::setColor(ccColor3B color)
{
    for (int i = 0; i < getChildren()->count(); i ++)
    {
        CCLabelTTF* child = (CCLabelTTF*)getChildren()->objectAtIndex(i);
        child->setColor(color);
    }
}

我认为,这是一个问题,许多可可2d开发商 st倒。 因此,为了改进这一类的可读性和协作性,我正在为之建立一个Github存放处。

Here is the link

我开始在@gmoagames(and @Hardschool)的版本上添加了setColor:。 “Alex”方法,并增加了一种方法,以纠正不透明性。

如果你有一些改进,我可以自由提出合并要求。

许多人感谢在这里分享的所有法典。
