Answer 1

Follow my code:
CGFloat btnX = 80.0;
int numberOfButton = 10;
for (int i = 1 ; i <= numberOfButton; i++)
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(newView:) forControlEvents:UIControlEventTouchDown];
button.tag = i;
[button setTitle:#"Excavations" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[scrollview addSubView:button];
btnX = btnX + 165.0;
}
scrollview.contentSize = CGSizeMake(btnX + 50, yourHeight);
Your warning says that you forgot to add method of your UIButton, so you need to declare method of button, such like..
-(void) newView:(UIButton *) sender
{
//you can access your button by it's tag.
}

Answer 2

- (void)createScrollViewMenu
{
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 100)];
int x = 0;
for (int i = 0; i < 10; i++) {
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(x, 0, 100, 100)];
[button setTitle:[NSString stringWithFormat:#"NameOfBtn %d", i] forState:UIControlStateNormal];
[button addTarget:self action:#selector(BtnClicked:) forControlEvents:UIControlEventTouchDown];
button.tag = i;
[scrollView addSubview:button];
x += button.frame.size.width;
}
scrollView.contentSize = CGSizeMake(x, scrollView.frame.size.height);
scrollView.backgroundColor = [UIColor redColor];
[self.view addSubview:scrollView];
}
This will create a scrollview with a height of 100, width as big as its parent, and add 10 buttons to it.
so you need to declare method of button, such like..
-(void)BtnClicked:(UIButton *) sender
{
//you can access your button by it's tag.
}
