Question

I am using with a sortDescriptor to sort my NSFetchRequest result. I am doing this.

NSFetchRequest *request = [NSFetchRequest fetchRequestWithEntityName:@"Team"];
    request.sortDescriptors = [NSArray arrayWithObject:[NSSortDescriptor sortDescriptorWithKey:@"position" ascending:YES]];

Position can be 4 values:

1. Atacker
2. Goalkeeper
3. Winger
4. Defender

At the moment it groups all the positions seperatyl. So first all the attackers, then all the goalkeepers, then all the defenders and finally all of the wingers. What I want to achieve now is to change the order of rank. The order of rank should be.

1. First all the goalkeepers
2. Second all the defenders
3. Third all the wingers
4. And lastly all the wingers

Anybody got an idea how I can do that ?

Thanks in advance!

Answer 1

A messy way of doing it would be to add an extra integer column representing each player type and sorting it by that instead.

EDIT: This isn’t necessarily a ‘messy’ method because it does the job however the only reason I had suggested it was messy was because you have to add in extra stuff so that you know the kind of player. Despite this, it is a reasonable method.
