Objects that are not added to NSMutableArray Objective -C

Question

I'm trying to just add objects to a mutable array, but they are NOT inserted. I do not get errors or anything else, and I can not understand what is happening.

In my main delegate file, I split the array into 4 separate lines.

NSArray *split=[currentParsedCharacterData componentsSeparatedByString:@"|"];
        NSLog([split objectAtIndex:3]);

        NSString *date=[split objectAtIndex:0];
        NSString *venue=[split objectAtIndex:1];
        NSString *event=[split objectAtIndex:2];
        NSString *city=[split objectAtIndex:3];

I traced string values, and they definitely exist.

Next I will try to add these string values ​​to mutable arrays.

[self.promoTabOptionEvents.dates addObject:date];
        [self.promoTabOptionEvents.venues addObject:venue];
        [self.promoTabOptionEvents.event addObject:event];
        [self.promoTabOptionEvents.city addObject:city];

When I check arrays in the debugger, they are empty. What am I doing wrong?

The promoTabOptionEvents class is as follows

import

@interface PromoTabOptionEvents : UIViewController {

    NSString *event_headline;
    NSMutableArray *dates;
    NSMutableArray *venues;
    NSMutableArray *event;
    NSMutableArray *city;

}

@property(nonatomic,retain)NSString *event_headline;
@property(nonatomic,retain)NSMutableArray *dates;
@property(nonatomic,retain)NSMutableArray *venues;
@property(nonatomic,retain)NSMutableArray *event;
@property(nonatomic,retain)NSMutableArray *city;
-(void)applyLabels;
-(id)initWithTabBar;
@end


#import "PromoTabOptionEvents.h"


@implementation PromoTabOptionEvents
@synthesize event_headline;
@synthesize dates;
@synthesize venues;
@synthesize event;
@synthesize city;

-(id) initWithTabBar {
    if ([self init]) {
        //this is the label on the tab button itself
        //self.title = @"Tab1";

        //use whatever image you want and add it to your project
        self.tabBarItem.image = [UIImage imageNamed:@"events.png"];

        // set the long name shown in the navigation bar
        self.navigationItem.title=@"Events";


        CGRect bgframe;
        bgframe.size.width=320; bgframe.size.height=460;
        bgframe.origin.x=0; bgframe.origin.y=0;
        UIImage* bgimage = [UIImage imageNamed:@"eventsbig.png"];
        UIImageView *imagebgview = [[UIImageView alloc] initWithImage: bgimage];
        imagebgview.frame=bgframe;
        imagebgview.contentMode=UIViewContentModeScaleAspectFit;
        self.view.backgroundColor=[UIColor whiteColor];
        [self.view addSubview:imagebgview];


    }
    return self;


}
