Question

Trying to implement the following structure from “c” to use NSArray in objective-c:

In standard-c:

struct structDog{
    char *name;
    int age;
};

struct structLitter{
    struct structDog puppy[10];
};

Then I use malloc to allocate space.
But since I am using NSArray.

But in Objective-c I am using NSArray… so ???

NSArray struct structDog *puppy; // <<---this doesn't work

thanks

Assuming that you are trying to do is get your struct into your NSArray you need to use NSValue. For instance you can do something like:

NSArray* myArray = [NSArray arrayWithObjects:[NSValue valueWithPointer: myDog],
                                             [NSValue valueWithPointer: myPuppy],
                                             nil];

structDog* dog = (structDog*)[[myArray objectAtIndex:0] pointerValue];
