Alternative UIButton addTarget: action: forControlEvents: method in IOS

I know this question has been asked so many times, but I want to pass a custom object as an argument when the button is clicked.

UIButton addTarget:action:forControlEvents:

does not allow us to do this, but it is important to me, so I can do further based on custom objects.

If an alternative for adding a target is possible, please give a solution.

The code looks like this:

Custom Object:

HeaderData *cell ;

Button

_forward =[UIButton buttonWithType:UIButtonTypeRoundedRect];
[_forward setTitle:@"F" forState:UIControlStateNormal];
_forward.frame = CGRectMake(300, (_CELL_HEIGHT-_LABEL_HEIGHT)/2, 10 ,_LABEL_HEIGHT);]
[_forward addTarget:web action:@selector(functionName:) forControlEvents:UIControlEventTouchUpInside];

and the function called when clicking the UIButton _forward is:

-(void)functionName:(UIButton *)sender{
    //code for further programming on the basis of cell.
}

You can create your own UIButton subclass:

@interface CustomDataButton : UIButton
@property (nonatomic, strong) id userData;
@end

Then in functionName you can pull the data:



-(void)functionName:(UIButton *)sender 
{
    if ([sender isKindOfClass:[CustomDataButton class]])
    {
        id customData = ((CustomDataButton *) sender).userData;
    }
}

caveat : written without IDE. Beware of typos, etc.
