Hide UIButton in Custom UITableViewCell

In my tableview, I have several different custom cells. In one of them, it has a button. This button brings up another view controller. However, It is not needed until the tableview has fully loaded. In cellForRowAtIndexPath I set up all my different custom cells. I can uncomment [buttonCell.myButton setHidden:YES]; and it will hide my button. See below.

else if (indexPath.section == 3)
{
    ButtonCell *buttonCell = [tableView dequeueReusableCellWithIdentifier:@"ButtonCell"];

    //[buttonCell.myButton setHidden:YES];
    cell = buttonCell;
}
    return cell;

However, I want to then unhide the button after the tableview loads. I finish loading all my arrays in another method where I call reloadData. In that method, I tried to unhide the button by doing this..

[ButtonCell.myButton setHidden:NO];

But the compiler gives me a warning that property myButton is not found in ButtonCell. Does anyone have any ideas how to go about unhiding my button. What am I doing wrong, and what do I not get! Thanks for all your help.

EDIT 1

My button cell class is... .h #import 

@interface ButtonCell : UITableViewCell

@property (strong, nonatomic) IBOutlet UIButton *myButton;
- (IBAction)YDI:(id)sender;


@end

.m

#import "ButtonCell.h"
#import "AnotherWebViewController.h"

@implementation ButtonCell

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
    // Initialization code
}
return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];

// Configure the view for the selected state
}

- (IBAction)YDI:(id)sender
{

}

@end

EDIT 2

With everyone's help that answered (thank you all) I have gotten a bit further, but the button is not showing itself. So I still hide the button in cellForRowAtIndexPath, that works as should. Then in my method that I reload the data in I put the following code.

NSIndexPath *index = [NSIndexPath indexPathForRow:0 inSection:3];
ButtonCell *buttonCell = (ButtonCell *) [self.tableView cellForRowAtIndexPath:index];
[buttonCell.myButton setHidden:NO];

The ButtonCell with the button is always the fourth section (counting the first as 0) and it only has one row. Any other help would be appreciated. Almost there!

EDIT 3 Got it! However, it was due to a comment that I was able to figure it out. Thanks to @A-Live. Although I do know how to get the cell in a method outside of cellForRowAtIndexPath thanks to ElJay. So I am giving him the check since I learned something new which is why we post questions anyway. So inside my method cellForRowAtIndexPath is where I hide/show the button. I have a BOOL in my App called finished, it is originally set to true. When the table view ends loading it is set to false. So I just used this bool to show/hide the button.

else if (indexPath.section == 3)
{
    ButtonCell *buttonCell = [tableView dequeueReusableCellWithIdentifier:@"ButtonCell"];

    if (!_finished)
    {
        [buttonCell.myButton setHidden:YES];
    }else{
        [buttonCell.myButton setHidden:NO];
    }

    cell = buttonCell;
}
    return cell;

Once again this is only part of my cellForRowAtIndexPath method. Thanks once again for all the help. I was surprised to see so many answers! Thanks.

Make the property publicaly accessible.

@property (nonatomic, retain) UIButton *myButton;

Then in cellForRowAtIndexpath

ButtonCell *buttonCell =(ButtonCell *) [tableView dequeueReusableCellWithIdentifier:@"ButtonCell"];

Do you have a public accessor for that property in the header file of ButtonCell? Something like @property (nonatomic, retain) UIButton *myButton;
This is how I usually see such a compiler warning.

Mistake in uppercase maybe ?

[buttonCell.myButton setHidden:NO]; // Trying to access instance variable

Instead of :

[ButtonCell.myButton setHidden:NO]; // Trying to access class variable

In your code

[ButtonCell.myButton setHidden:NO];

You are trying to use the object class name instead of the object name. You need to get the cell that contains your button

buttonCell = [tableView cellForRowAtIndexPath:indexPath];
buttonCell.myButton.hidden = NO;

myButton belongs to a cell. You will need to get an instance of that UITableViewCell and then you can unhide it, this assumes you want to modify the cell's objects outside of cellForRowAtIndexPsth or willDisplayCell.
