Use the following method to save data

-(NSString*)saveFilePath    {

        NSArray *pathArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *pathString = [[pathArray objectAtIndex:0] stringByAppendingPathComponent:@"data"];
        //NSString *pathString = [[NSBundle mainBundle]pathForResource:@"Profile" ofType:@"plist"];
        return pathString;

    }

-(void)saveProfile  {
    SeccionItem *data = [[SeccionItem alloc]init]
    data. title = @"title";
    data. texto = @"fdgdf";
    data.images = [NSArray arrayWithObjects:@"dfds", nil];


    NSMutableData *pData = [[NSMutableData alloc]init];

    NSString *path = [self saveFilePath];

    NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc]initForWritingWithMutableData:pData];
    [data encodeWithCoder:archiver];
    [archiver finishEncoding];
    [pData writeToFile:path atomically:YES];

}

Use the following method to load data

-(void)loadData {

    NSString* path = [self saveFilePath];
    //NSLog(path);
    NSMutableData *pData = [[NSMutableData alloc]initWithContentsOfFile:path];

    NSKeyedUnarchiver *unArchiver = [[NSKeyedUnarchiver alloc]initForReadingWithData:pData];
    data = [[SeccionItem alloc]initWithCoder:unArchiver];
    //NSLog(@"%@",data.firstName);
    [unArchiver finishDecoding];

}
