Passing an object to a class through another class - ios

Question

I have a tableview controller class, a tableviewcell subclass and a uibutton subclass.
I am creating an instance of the unbutton subclass in the tableviewcell subclass and initialize a button in a specific cell position.
Then I am using this cell in the tableview controller class. Also I am trying to add an IBAction to the button. But it can't recognize the object of the uibutton subclass while everything else works fine. What am I doing wrong in the declaration?
tableviewcell.m
#import "tableviewcell.h"
#import "CustomCheckButton.h"
CustomCheckButton *starbtn = [[CustomCheckButton alloc] init];;
starbtn = [[CustomCheckButton alloc]initWithFrame:CGRectMake(243,0, 30, 30)];
tableviewcontroller.m
In the cellForRowAtIndexPath object startbtn won't be recognized:
#import "ScannedProductControllerViewController.h"
#import "imageCellCell.h"
tableviewcell*firstRowCell = (tableviewcell *)cell;
[firstRowCell.prodimage setImage: [UIImage imageNamed:#"test1.jpg"]];
[firstRowCell.label1 setText:#"17.5"];
[firstRowCell.label2 setText:#"Score"];
[firstRowCell.basket setImage: [UIImage imageNamed:#"Basket.jpg"]];
// reference of the home button to the buttonclick method
[firstRowCell.homebtn addTarget:self action:#selector(clickButton:) forControlEvents:UIControlEventTouchUpInside];
// reference of the favorites button to the buttonclick method
[firstRowCell.starbtn addTarget:self action:#selector(clickFavButton:) forControlEvents:UIControlEventTouchUpInside];
CustomCheckButton.h
#import <UIKit/UIKit.h>
#interface CustomCheckButton : UIButton {
BOOL _checked;
}
#property (nonatomic, setter = setChecked:) BOOL checked;
-(void) setChecked:(BOOL) check;
#end

#interface TableViewCell : UITableViewCell
#property (nonatomic, strong) CustomCheckButton *startButton;
#end
#implementation TableViewCell
- (instancetype)init {
self = [super init];
self.startButton = [[CustomCheckButton alloc]initWithFrame:CGRectMake(243,0, 30, 30)];
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.contentView addSubview:self.startButton];
}
#end

First, why don't you create your cells in the storyboard as a prototype cell or inside of a XIB file.
Then, create an IBAction to the button and respond to it in the cell. Finally, make a protocol for your cell that will inform the delegate when the button is tapped. You can then setup your table view controller as the delegate of the cells and respond to the button tapped. If you need to determine which cell you're working with, you can even pass the cell as a parameter of one of the protocol's methods you use.
