Saving/Retrieving NSMutableArray after relaunch

[Whitehk]

Here's what I have so far which works to an extent:

CustomClass.h:

#import <Foundation/Foundation.h>


@interface CustomClass : NSObject <NSCoding> {
    NSString *name;
    float value1;
    
    int value2;
}

-(NSString*)name;
-(float)value1;
-(int)value2;

-(void)setName:(NSString *)input;
-(void)setValue1:(float)input;
-(void)setValue2:(int)input;

@end

CustomClass.m:

#import "CustomClass.h"


@implementation CustomClass

-(id)initWithCoder:(NSCoder *)coder {
	self = [[CustomClass alloc] init];
    if (self != nil) {
		self.name = [coder decodeObjectForKey:@"name"];
	}
	
	return self;
}

-(void)encodeWithCoder:(NSCoder *)coder {
	[coder encodeObject:name forKey:@"name"];
	
}

-(int)value2 {
    return value2;
}

-(float)value1 {
    return value1;
}

-(NSString*)name {
    return name;
}

-(void)setValue1:(float)input {
    value1 = input;
}

-(void)setValue2:(int)input {
    value2 = input;
}

-(void)setName:(NSString *)input {
    [input retain];
    [name release];
    name = input;
}

-(void)dealloc {
    [super dealloc];
    
    [name release];
}

@end

Save Array:

   NSUserDefaults *currentDefaults = [NSUserDefaults standardUserDefaults];
    [currentDefaults setObject:[NSKeyedArchiver archivedDataWithRootObject:dataArray] forKey:@"savedArray"];
    [currentDefaults synchronize];

Retrieve Array:

    dataArray = [[NSMutableArray alloc] init];
	
    NSUserDefaults *currentDefaults = [NSUserDefaults standardUserDefaults];
    NSData *dataRepresentingSavedArray = [currentDefaults objectForKey:@"savedArray"];
    if (dataRepresentingSavedArray != nil) {
        NSArray *oldSavedArray = [NSKeyedUnarchiver unarchiveObjectWithData:dataRepresentingSavedArray];
        if(oldSavedArray != nil) {
            dataArray = [[NSMutableArray alloc] initWithArray:oldSavedArray];
        }
        else {
            dataArray = [[NSMutableArray alloc] init];
        }
    }

This works to save and load an array of my custom objects to a table view. The only problem: the custom objects value's have been reset when I relaunch. I want to maintain the values of my custom objects (i.e. the name, value1, and value2). Can someone tell me where I went wrong? Thanks.

In your initWithCoder and encodeWithCoder, you need to include all of your objects.

A float and integer aren't objects. Are they? Whenever I try to include them in the initWithCoder and encodeWithCoder methods, it says, "assigning to 'float' from incompatible type 'id'" and "incompatible pointer to integer conversion assigning to 'int' from 'id'". Even if that's the case, the name string is also lost even though I included this in the initWithCoder and encodeWithCoder methods.

Sorry I didn't use the right word, all the data that you want to save must go into those methods. I believe there are specific methods for floats and int. Probably [coder decodeFloat...] and [coder encodeFloat...].

Thank you! That fixed it! I knew it was a stupid mistake like that... Usually is. XD
