为二维数组的大小声明常量

I'm beginning Objective-C and I'm trying to create a multidimensionnal array of integers, here is how I did it :

我开始了Objective-C我想创建一个多维的整数数组，我是这样做的:

File Constants.h (added in the Prefix.pch file)

文件常数。h(加上前缀。pch文件)

typedef enum {
    BOARD_WIDTH=10,
    BOARD_HEIGHT=20
} BoardSizeEnum;

File Board.m

文件Board.m

@implementation Board
{
    NSInteger mBoard[BOARD_WIDTH][BOARD_HEIGHT];
}

I tried many many way of creating constants for my width and height and this way is the only one that seems (quite) correct... I also tried with define but I don't like this because it's not typed (am I wrong for thinking that ?)...

我尝试了很多方法来为我的宽度和高度创建常量，这种方法是唯一看起来(非常)正确的方法。我也尝试过define，但我不喜欢这个，因为它没有类型(我这样想是错的吗?)

Is there a better way of creating this ? I feel it's not really clean...

有更好的方法来创造这个吗?我觉得不太干净……

Edit :
NSInteger* to NSInteger, I clearly want an array of integers, not pointers.

编辑:NSInteger*到NSInteger，我显然想要一个整数数组，而不是指针。

You shouldn't declare the sizes like that. Enums are usually used when you have multiple options and you want to give each option a name (instead of just using numbers).

你不应该这样申报尺寸。枚举通常用于当您有多个选项并且您想给每个选项一个名称(而不是仅仅使用数字)时。

To declare constants for your array, you have a few options.

要为您的数组声明常量，您有几个选项。

Use preprocessor macros:

使用预处理器宏:

#define BOARD_WIDTH 10

#定义BOARD_WIDTH 10
Use constants:

用常量:

static const int boardWidth = 10;

静态const int boardWidth = 10;

And your declaration is wrong. You're declaring a 2 dimensional array of NSInteger pointers. It should be like this instead:

你的声明是错误的。声明一个二维NSInteger指针数组。应该是这样的:

// assuming width and height is declared as described above.
NSInteger mBoard[width][height];

#2

NSMutableArray *words[26];
    for (i = 0;i<26;) {
    words[i] = [[NSMutableArray alloc] init];
    }

you can use it like this

你可以这样使用它

[words[6] addObject:myInt];
[words[6] insertObject:myInt atIndex:4];
[words[6] objectAtIndex:4];
//in this case 6 is the column number and 4 is the row.
