Cocos2d iphone 什么是多行？

有没有办法使菜单项多行？ 我试过了

但这似乎不起作用

您忘了在代码片段的CCMenuItemFont之后添加“*”。 我使用标签创建多行项目，如下所示：

CCLabelTTF *label = [CCLabelTTF labelWithString:@"Map\n Packs" dimensions:CGSizeMake(100, 100) 
                                           alignment:UITextAlignmentCenter 
                                           fontName:@"Arial" fontSize:22];
CCMenuItemFont *mapPacks = [CCMenuItemFont itemWithLabel:label target:self selector:@selector(mapPacks:)];

CCLabelTTF *label = [CCLabelTTF labelWithString:@"Map\n Packs" dimensions:CGSizeMake(100, 100) 
                                           alignment:UITextAlignmentCenter 
                                           fontName:@"Arial" fontSize:22];
CCMenuItemFont *mapPacks = [CCMenuItemFont itemWithLabel:label target:self selector:@selector(mapPacks:)];
