Answer 1

You need to tell the compiler that sender is, in fact, a UIButton:

- (IBAction)Getcompany:(id)sender {
    UIButton *button = (UIButton *)sender;
    SecondViewController *popoverview=[self.storyboard instantiateViewControllerWithIdentifier:@"popover"];
    self.popOver =[[UIPopoverController alloc] initWithContentViewController:popoverview];
    [self.popOver presentPopoverFromRect:button.frame  inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
}

-or-

you can use the form:

[sender frame]

rather than:

sender.frame

NOTE: the name Getcompany is not conventional for an Objective-C method; I don't know what it does, but if it's an action method, then something like this is probably better:

- (IBAction)companyButtonPressed:(id)sender 

(note lowercase starting letter and camel-case formatting).
