我正在尝试使用CCLabelTTF在cocos2d 1.0中创建多行标签。我已经尝试过我遇到过的例子,但似乎都没有。这就是我所拥有的
CCLabelTTF *storeLabelHeading = [CCLabelTTF labelWithString:@"Here is a really long string that I want to wrap"
dimensions: CGSizeMake(200,0)
alignment: NSTextAlignmentCenter
lineBreakMode: NSLineBreakByWordWrapping
fontName:@"Marker Felt" fontSize: 24];
storeLabelHeading.color = ccc3(0,0,0);
[storeLabelHeading setAnchorPoint:ccp(0,0)];
storeLabelHeading.position = ccp(screenSize.width * 0.35f,
screenSize.height * 0.85);
[self addChild:storeLabelHeading z:kStoreLayer+10];
我尝试了各种各样的尺寸。如果我使用CGSizeMake(0,0),那么标签将显示,但没有换行(我认为是预期的)。但任何其他值都不会显示任何内容。我做错了什么?

根据你的问题,我得到了与cocos2d 2.0相同的结果,没有自动换行。但是,我让它正常工作:
CCTexture2D *tex =[ [[CCTexture2D alloc]
initWithString:@"Here is a really long string that I want to wrap wrap wrap"
dimensions:CGSizeMake(120, 120)
hAlignment:kCCTextAlignmentCenter
vAlignment:kCCVerticalTextAlignmentCenter
lineBreakMode:kCCLineBreakModeWordWrap
fontName:@"Marker Felt"
fontSize:24 ] autorelease];
CCSprite *spr = [CCSprite spriteWithTexture:tex];
[self addChild:spr];
spr.position=ccp(kScreenWidth/2,kScreenHeight/2);
奇怪的是,在通过CCLabelTTF ctor时,它失败了。然而,CCLabelTTF使用它来创建标签。这可能与垂直对齐在管道中的某处错误处理有关。
ps:这也有效
CCLabelTTF *storeLabelHeading = [CCLabelTTF labelWithString:@"Here is a really long string that I want to wrap"
dimensions: CGSizeMake(120,120)
hAlignment: kCCTextAlignmentLeft
lineBreakMode: kCCLineBreakModeWordWrap
fontName:@"Marker Felt" fontSize: 24];
storeLabelHeading.verticalAlignment=kCCVerticalTextAlignmentCenter;
storeLabelHeading.color = ccc3(0,0,0);
[storeLabelHeading setAnchorPoint:ccp(0,0)];
storeLabelHeading.position = ccp(kScreenWidth * 0.35f,
kScreenHeight * 0.85);
[self addChild:storeLabelHeading z:1+10];
[storeLabelHeading setString:@"Here is a really long string that I want to wrap wrap wrap"];
将垂直对齐设置为中心后设置字符串'unbreaks'CCLabelTTF ctor。

您还需要给出标签的高度尺寸。现在你传递200,0,尝试传递非零高度
