Courses Plus Student 2,925 PointsPlease help me on this NSMutableDictionary example. Ive been stuck for ages and it wont work even tho code is good.
Please help me with the answer.
Been stuck for ages.
NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer", @"brown"];
NSMutableDictionary *shoeOrderDict;
shoeOrderDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"@Charles Smith", @(9.5), @"@loafer", @"@brown", nil];
NSString *customer;
customer = [shoeOrder objectAtIndex: 0];
NSString *size;
size = [shoeOrder objectAtIndex: 1];
NSString *style;
style = [shoeOrder objectAtIndex: 2];
NSString *color;
color = [shoeOrder objectAtIndex: 3];
NSLog(@"Customer: %@ \n Size: %@ \n Style: %@ \n Color: %@", customer, size, style, color);

11,267 Pointsthe correct code is
NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer",@"brown"];
NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc] init];
[shoeOrderDict setObject:[shoeOrder objectAtIndex:0] forKey:@"customer"];
[shoeOrderDict setObject:[shoeOrder objectAtIndex:1] forKey:@"size"];
[shoeOrderDict setObject:[shoeOrder objectAtIndex:2] forKey:@"style"];
[shoeOrderDict setObject:[shoeOrder objectAtIndex:3] forKey:@"color"];
in the second line we declare an Empty NSMutableArray using the [[NSMutableDictionary alloc] init]; call, then we get every item in the shoeOrder NSArray using the and objectAtIndex method and finally we add the respective key in using the setObject: forKey: with the given keys, in order to complete the challenge.
Good luck and keep coding!
