Question

In a NSMutableDictionary like this:

[NSMutableDictionary dictionaryWithObjectsAndKeys:
[NSString stringWithString:firstName], @"NAME",
[NSNumber numberWithFloat:familyName], @"SURNAME",
nil];

How can all of its elements be converted to the NSString? with the requirement that names and surnames are arranged in string like this: “name, surname, name, surname…”?

This gives a string with all the names but not surnames:

NSString * result = [[urlArray valueForKey:@"NAME"] componentsJoinedByString:@", "];

Is there a way similar to the one above to create a string with all the values of NSMutableDictionary?

Answer 1

Try something like this:

NSString *result = [NSString stringWithFormat:@"%@, %@", [urlArray valueForKey:@"SURNAME"], [urlArray valueForKey:@"NAME"]];

The %@ represents an objective-c object for more details see the Apple docs
