Question

Is there a good way to convert a vector<int32_t> to an NSArray of NSNumber or is looping and adding to an NSMutableArray pretty much the only way?

Answer 1

If you have a vector of objects, you can do the following:

NSArray *myArray = [NSArray arrayWithObjects:&vector[0] count:vector.size()];

However, if your vector contains primitive types, such as NSInteger, int, float, etc., you would have to manually loop the values in the vector and convert them to a NSNumber first.
