将CCMenu对齐到网格 [英] Aligning CCMenu to a grid

问题描述

有没有人知道最佳实践方法获得一个CCMenuItems数组对齐网格？这是一个cocos2d问题

Does anybody know the best practice approach to getting an array of CCMenuItems to align to a grid? This is a cocos2d question

例如：

int levelCount = 10;

CCMenu *menuArray = [CCMenu menuWithItems:nil];

for (int x = 1; x<=levelCount; x++) {
    CCLOG(@"Creating level icon for Level %i", x);     
    [menuArray addChild:[CCMenuItemImage itemFromNormalImage:@"Button2n.png" 
                                               selectedImage:@"Button2s.png" 
                                                      target:self 
                                                    selector:@selector(onPlay:)]];

}

[menuArray alignToGridWouldbeGreat????!!!!];
[self addChild:menuArray];

我可以在列或行中垂直，水平排列，但不能包括列或行配置。

I can align vertically, horizontally, in columns or rows however cannot wrap a column or row configuration.

提前感谢！

推荐答案

的重载的alignItemsInColumns或alignItemsInRows方法。例如，如果您有15个菜单项，并且您想要3行5列，请执行以下操作：

You just have to call one of the overloaded alignItemsInColumns or alignItemsInRows methods. For example if you have 15 menu items and you want 3 rows of 5 columns, do this:

CCMenu* menu = [CCMenu menuWithItems:...];
NSNumber* itemsPerRow = [NSNumber numberWithInt:5];
[menu alignItemsInColumns:itemsPerRow, itemsPerRow, itemsPerRow, nil];

唯一的缺点是，似乎没有办法设置填充，一个网格。

The only down side is that there doesn't seem to be a way to set padding when aligning to a grid.
