Use :
Nodes *node = [Nodes alloc];
NSMutableArray *arr =[[NSMutableArray alloc]init];
[arr addObject:node];

I am getting error at this line Nodes *node = [Nodes alloc]; say undefined symbols Nodes and node. I tried using type def typedef struct Nodes NodeStruct; and rewritten the code this way. NodeStruct *node;// = [NodeStruct alloc]; NSMutableArray *arr =[[NSMutableArray alloc]init]; [arr addObject:node]; Then I am getting the error in the last line sayingpassing argument of incompatable type.
My suggestion for you would be to use class instead of struct:
@interface Nodes : NSObject{
NSInteger nodeGridNumber;
Boolean visited;
struct Nodes *nextNode;
};
Then you could add it to NSMutableArray. And of course, import class header file, where you need to use this class.
