Question

I have an object that I convert into NSData using an NSKeyedArchiver and then store it into NSUserDefaults. Everything gets saved correctly except for the elements of an array that the object has. All the objects in the array have conform to the NSCoder protocols (or whatever theyre called- ex. self.property = [decoder decodeObjectForKey:@"key"] and [encoder encodeObjectForKey:@"key"])

When I save the object, the elements of the array remain in the array, but their properties themselves do not get saved. i DO call the sycnrhonize method, so that is not the issue.

NOTE that all other times i save & load it is correct, it just does not save the elements of an array that belongs to an object. Do i have to save that separately?

The "current status" NSNumber is not being saved. Objective and target are being saved

import "Level.h"

@implementation Level
@synthesize objective = _objective;
@synthesize isComplete = _isComplete;
@synthesize goldReward = _goldReward;
@synthesize xpReward = _xpReward;
@synthesize missionID = _missionID;
@synthesize currentStatus = _currentStatus;
@synthesize targetName = _targetName;
@synthesize owner = _owner;

-(void)dealloc{

[super dealloc];
  }

-(id)initWithMissionID:(int)number{

if (self = [super init]) {
    self.currentStatus = 0;
    self.isComplete = NO;
    self.missionID = [NSNumber numberWithInt:number];
    [self setUpMisson];
}
return self;
}
-(void)setUpMisson{
if ([self.missionID intValue] == 0) {
    self.xpReward = [NSNumber numberWithInt:100];
    self.goldReward = [NSNumber numberWithInt:100];
    self.objective = [NSNumber numberWithInt:3];
    self.targetName = @"Swordsman";
    CCLOG(@"Gotta kill some swordsmen!");
}
}
-(void)encodeWithCoder:(NSCoder *)encoder{
[encoder encodeObject:self.objective forKey:@"objective"];
[encoder encodeObject:self.isComplete forKey:@"isComplete"];

[encoder encodeObject:self.missionID forKey:@"missionID"];
[encoder encodeObject:self.currentStatus forKey:@"currentStatus"];
[encoder encodeObject:self.targetName forKey:@"targetName"];
[encoder encodeObject:self.owner forKey:@"owner"];
CCLOG(@"SAVING LEVEL");
}
-(id)initWithCoder:(NSCoder *)decoder{
if (self = [super init]) {
    self.objective = [[decoder decodeObjectForKey:@"objective"]retain];
    self.isComplete = [[decoder decodeObjectForKey:@"isComplete"]retain];
    self.goldReward = [[decoder decodeObjectForKey:@"goldReward"]retain];
    self.xpReward = [[decoder decodeObjectForKey:@"xpReward"]retain];
    self.missionID = [[decoder decodeObjectForKey:@"missionID"]retain];
    self.targetName = [[decoder decodeObjectForKey:@"targetName"]retain];
    self.owner = [[decoder decodeObjectForKey:@"owner"]retain];
    CCLOG(@"LOADING LEVEL");
}
return self;
}
-(void)updateStatusForKill:(AI *)killedTarget{
CCLOG(@"WE KILLED: %@ and OUR GOAL IS: %@",killedTarget.name,self.targetName);

if ([killedTarget.name isEqualToString:self.targetName]) {
    [self setCurrentStatus:[NSNumber numberWithInt:[self.currentStatus intValue]+1]];
    CCLOG(@"Current Status: %i Objective: %i", [self.currentStatus intValue],[self.objective intValue]);
    if ([self.currentStatus intValue] == [self.objective intValue]) {
        [self completeMission];
    }
}
}
-(void)completeMission{
[self.owner setCoins:[NSNumber numberWithInt:[[self.owner coins]intValue] + [self.goldReward intValue]]];
[self.owner setXp:[NSNumber numberWithInt:[[self.owner xp]intValue] + [self.xpReward intValue]]];
CCLOG(@"complete");
[[self.owner missionList]removeObject:self];

}
@end

EDIT: The "owner" refers back to the object being saved. I think this is where the problem is, so I’m removing that and testing again.

EDIT: and that did nothing!

found a workaround using a Unique-Id system for each mission and saving the progress for each mission separately into NSUserDefaults which are just then loaded again. Not ideal, but it works. Thanks for everyone’s help!
