5,999 PointsHow to add an array of items into an NSMutableDictionary with an already declared array for the values.
I'm having a very hard time figuring out the syntax to use objectAtIndex to load an NSMutableDictionary.. this is what I found on stack overflow, but I'm not getting something..
NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer", @"brown"];
NSMutableDictionary *shoeOrderDict= [[NSMutableDictionary alloc] init];

NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer", @"brown"];
NSMutableDictionary *shoeOrderDict= [[NSMutableDictionary alloc] init];
shoeOrderDict[@"customer"] = [shoeOrder objectAtIndex: 0];
shoeOrderDict[@"size"] = [shoeOrder objectAtIndex: 1];
shoeOrderDict[@"style"] = [shoeOrder objectAtIndex: 2];
shoeOrderDict[@"color"] = [shoeOrder objectAtIndex: 3];
Of course, there are other ways to do this. E.g., using a loop. But this works too.
