You can check what type int32_t (or uint32_t) is typedef'd to and use that
corresponding type on your intended platform. Sort of like:
- (int32_t) int32Value
{
if (!strcmp(@encode(int32_t), @encode(int))
return [self intValue];
else if (!strcmp(@encode(int32_t), @encode(long))
return [self longValue];
else
return 0;
}
