iOS Objective-C Basics (Retired) Foundation Framework NSDictionary

Let's add the year of the album to the 'albumMutable' variable. Where the key is a NSString 'year' and the value is also a NSString '1969'.

NSDictionary *album = @{ @"title": @"Abbey Road", @"artist": @"The Beatles"}; NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary: album]; [albumMutable setObject: @1969 forKey:@"year"];

What am I doing wrong?

1 Answer

it tells you to add the value '1969' as an NSString. so when adding it with setObject, you have to correctly identify it with the correct literal. i.e. @"1969"

Thanx David

No Problem. I did the exact same thing on that question. In the video they add it as an integer, and I didn't fully read the question properly. Easy mistake.
