Adding an object to array but still the content length is zero

I have an ivar, NSMutableArray *bodies;. I allocate and initialize it inside the init method. Then in another place I'm doing the following:

b2Body *body=_world->CreateBody(&bodyDef);
NSValue *bodyValue=[NSValue valueWithPointer:body];
[bodies addObject:bodyValue];

When I debug the code the body is a valid object but although I add it to the bodies array, the array remains empty. If I do something like this

[bodies addObject:@"An object"];

then the count of the objects in bodies is 1. What might be the problem? I needed a way to store C++ objects into a mutable array.

Yeah, but all the threads are answered making a conclusion that the NSMutableArray was probably not initialized. It's not the case with me. I have initialized it in the init method. And besides that, why does a string object get added to the same array? – Mikayil Abdullayev Mar 28 '13 at 20:17
Check the value of `bodies` right before you add `bodyValue`. – jscs Mar 28 '13 at 20:20
It's a valid body. Because I use it afterwards – Mikayil Abdullayev Mar 28 '13 at 20:22
The value of `bodies`, the _array_, not `bodyValue`. – jscs Mar 28 '13 at 20:24
@JoshCaswell, yes, I really was messing everything up with reallocating the filled array afterwards. So, I voted to get the thread closed. – Mikayil Abdullayev Mar 28 '13 at 20:35
