how to send array value to another class

I have problem with send array value to another class. I'm sure that it's obvious but I don't have any idea to do this.

I'll be glad for any example code.

Problem: class1 send text from searchBar to class2. In class2 I get a data from www[JSONModel] and generate an array. My problem is how to send value this array to class1 and make reloadData in tableView.

To send data from class1 to class2 I use delegate method [SearchTextDelegate] I tried to make next delegate to send data from class2 to class1 but it doesn't work.

Thanks in advance.

my class1.m:

#pragma mark - searchBar
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)text {

    self.mySearchText = [NSString stringWithFormat:@"%@", text];
    NSLog(@"mySearchText: %@", self.mySearchText);

    if (text != 0) {

        APIClient *wskAPI = [[APIClient alloc]init];
        wskAPI.delegate = self;
        wskAPI.searchText = self.mySearchText;
        [wskAPI createSearchString];
    }
    [self.tableView reloadData];
}

#pragma mark - Sample protocol delegate
-(void)searchProcessCompleted {

    [self.tableView reloadData];
}

my class2.h [APIClient.h]:

#import <Foundation/Foundation.h>
#import "ITunesResultModel.h"

@protocol SearchTextDelegate <NSObject>

-(void)searchProcessCompleted;

@end

@interface APIClient : NSObject

@property (strong, nonatomic) id delegate;
@property (assign) id <SearchTextDelegate> stringDelegate;

@property (strong, nonatomic) NSString *searchString;
@property (strong, nonatomic) NSString *searchText;

@property (strong, nonatomic) ITunesResultModel *iTunesModel;
@property (strong, nonatomic) NSArray *resultArray;

-(void)createSearchString;

@end

my class2.m [APIClient.m]:

#import "APIClient.h"
#import "ITunesResultModel.h"
#import "JSONModelLib.h"
#import "class1.h"

@implementation APIClient

static NSString * const ITunesOnlineURLString = @"http://ift.tt/1CToUkG";

-(void)createSearchString {

    NSLog(@"searchTextAPI: %@", self.searchText);

    self.searchString = [NSString stringWithFormat:@"http://ift.tt/1j7O455", self.searchText];

    //fetch the feed
    self.iTunesModel = [[ITunesResultModel alloc] initFromURLWithString:self.searchString
                                         completion:^(JSONModel *model, JSONModelError *err) {

                                             //json fetched
                                             //NSLog(@"result: %@", self.iTunesModel.results);

                                         }];  
}

@end
