Answer 1

Assuming that your question is how to change the image of a button w/in every cell of your table when a bar button is clicked, I suggest the following:
Within tableView:cellForRowAtIndexPath, add:
btnCheck.tag = MY_BUTTON_TAG_NUMBER;
Then, when the bar button item is clicked, loop through the visible cells and use the button's tag to identify it and update its image.
-(IBAction)bbtnCheck:(id)sender {
for (UITableViewCell *cell in self.tableView.visibleCells) {
UIButton *button = [cell viewWithTag:MY_BUTTON_TAG_NUMBER];
[button setImage:[UIImage imageNamed:SOME_NEW_IMAGE] forState:UIControlStateNormal];
}
}

In that bbtnCheck you have to get the instance of that tableView (i.e. particular cell)..Then after you can get buttons added on that particular cell..
Please Check this....
-(IBAction)bbtnCheck:(id)sender
{
NSIndexPath *indexpath = [NSIndexPath indexPathForRow:YourRow inSection:YourSection]; // you have to set Row and Section according to your requirement
UITableViewCell *cellNew = [self.tblComments cellForRowAtIndexPath:indexpath];
for (UIButton *btn in [cellNew.contentView subviews])
{
if ([btn isKindOfClass:[UIButton class]])
{
[btn setImage:[UIImage imageNamed:#"yourImage.png"] forState:UIControlStateNormal];
}
}
}
