Question

In my code I have written this but it fails to compile:

In Class1.h:

@interface Class1 : CCSprite
{
    NSMutableArray *leafArr[20][20];
}

@property(readwrite, assign) NSMutableArray *leafArr; 
@end

In Class1.m:

@implementation

@synthesize leafArr[20][20];
@end

But this fails to compile, please can you tell me how to make set and set method for a 2D array?

Answer 1

There’s no way of creating a 2D array in Obj-C, the only thing you can do is create a normal array, and then add arrays to it.

@interface Class1 : CCSprite
{
    NSMutableArray *leafArr;
}

@property(readwrite, assign) NSMutableArray *leafArr; 
@end

And you add elements with:

[leafArr addObject:mySecondArray];
