Question

I am trying to extract an int inside of a NSValue / NSConcreteValue instance. I tried to cast them this way, but it didn’t work:

    NSValue *toValue = (NSValue *)someValue;
    NSNumber *toNumber = (NSNumber*)toValue;
    int final = [toNumber intValue];

I also tried using getValue but that also didn’t work for me.

Answer 1

Are you sure an int was saved into it? If yes you might get it with:

int final = 0;
[someValue getValue:&final];

you know you can ask a NSValue its type with

[value objCType]

which returns a const char *
