NSString format issue - {( String )}

Question

I am fetching data from core data and trying to print the name of the object at valueForKey. This has never caused me any trouble however when getting a direct object but the object I am getting is from an NSSet relationship.

When I print out the value I want, it displays in this format.

{(
     Bob Marley
)}
{(
    Jack Daniels
)}
etc...

I have used NSString stringWithFormat, I have tried componentsSeperatedByString, however neither of these work. If another question has been asked, I cannot find it on here. The issue is identical in a UILabel as well. Makes no difference where I print it.

Hopefully it's a simple issue.

My code for getting the value is.

//Company * company
//Employee is related in a many-many relationship
NSString * name = (NSString *)[self.company.contractor valueForKey:@"contractorName"];
        NSLog(@"Name: %@", name);

Thanks.

you should use managed object to retrieve the data from core data that will help — Smile

I am using a fetchedResults controller to get the results, how would using managedObject make a difference? I have never had to use it as fetchedResults get's me what I have needed in the past. — App Dev Guy

self.company.contractor is NSArray.

So you need to do

NSString * name = (NSString *)[[[self.company.contractor allObjects] firstObject] valueForKey:@"contractorName"];

Also refer to my previous answer

Sorry, that is not correct. self.company.contractor is an NSSet not NSArray. So firstObject does not work. This is the message when trying your solution: "No visible @interface for 'NSSet' declares the selector 'firstObject'"
