5,225 PointsHow to add elements to NSMutableDictionary
I have been through the videos again and again and have tried to find the answer out online, but everything I try results in errors. How do I add elements from the NSArray to the NSMutableDictionary?
NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer", @"brown"];
NSMutableDictionary *shoeOrderDict;
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”];

[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"];
