Question

My NSMutableArray contain the list of GroupUser objects :

@interface GroupUser : NSObject {

    NSString *groupUser_name;//user name
    NSString *groupUser_customMsg;
    NSString *groupUser_emailId;
    NSString *groupUser_groupName;
    NSString *groupUser_aliasName;
    int groupUser_imageId;
    int groupUser_state;//whether user is online( value 0) offline(value 1) or busy(value 2)
    int groupUser_type;             
}

now i want to sort the list :
1. On the bases of groupUser_state
2. On the bases of groupUser_name

eg:: 1. Sam Offline(value 1)
2. Ravi Online(value 0)
3. Amit Online(value 0)
4. Ganga Online(value 0)
5. Durga Offline(value 1)

Output after sorting should be::
1. Amit Online
2. Ganga Online
3. Ravi Online
4. Durga Offline
5. Sam Offline

Help me by providing code for the same.. Thanx in advance

NSSortDescriptor *desc=[NSSortDescriptor  sortDescriptorWithKey:@"groupUser_state" ascending:YES];
NSArray *yourArray;
[yourArray sortedArrayUsingDescriptors:[NSArray arrayWithObject:desc]];
