First you need to set tags for each buttons. This can be done by

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//Your code
cell.Button.tag = indexPath.row;
[cell.Button addTarget:self action:@selector(buttonClick1:) forControlEvents:UIControlEventTouchUpInside];

}

Then you can get the button from this method

- (IBAction)buttonClick1:(id)sender {

int tagNo =[sender tag];
UITableViewCell *cellclicked = [self.tblProfileFollowing cellForRowAtIndexPath:[NSIndexPath indexPathForRow:tagNo inSection:0]];
//Now change the action for the cell
[cellclicked.Button addTarget:self action:@selector(buttonClick2:) forControlEvents:UIControlEventTouchUpInside];

//Your Code

}

You can follow the same steps for - (IBAction)buttonClick2:(id)sender

Now you can track which button was clicked and change the method for that button.

And declare your cell and button strong.

You can query your table view for all visible cells through -visibleCells, get the reference of your button (assuming you have a UITableViewCell subclass with a property for the button) and change them.

What you can do is Write a function which will change the values of the buttons and then you can call that function. After changing button values then use any one of the mentioned method below:

You can use either : [tableview reloadData]; to reload all the table data.

OR

You can reload particular rows using the following method :

[tableview reloadRowsAtIndexPaths: indexPath withRowAnimation:anyKindOfAnimation];
