Question

I want to add buttons one below the other. I have this simple code:

- (void)viewDidLoad
{
    [super viewDidLoad];

    for(int i=0 ; i<9 ; i++)
    {
        UIButton *myButton = [[UIButton alloc] init];
        myButton.frame = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height/10); //this "10" i want also dynamically
        myButton.backgroundColor = [UIColor blackColor];
        [self.view addSubview:myButton];
    }

}

Of course i know that it will be draw one on another. But can i do it in the loop without knowing the height (becouse high will depends on how many buttons will be in the loop).

What i want to achieve:

Answer 1

Try This:

- (void)viewDidLoad
  {
    [super viewDidLoad];
    int number = 10;

     for(int i=0 ; i<9 ; i++)
    {
    UIButton *myButton = [[UIButton alloc] init];
    myButton.frame = CGRectMake(self.view.frame.origin.x, (self.view.frame.size.height/number)*i + number, self.view.frame.size.width, self.view.frame.size.height/number);
    myButton.backgroundColor = [UIColor blackColor];
    [self.view addSubview:myButton];
    }


}
