Answer 1

After creating UIButton and setting it's frame like UITextField, you should use button's setFrame: method to change the position of it.

If you like to change the position with pressing button, first create a -(IBAction *)buttonPressed:(id)sender method and set button's new position in it. Then add the [button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside] method after where you create the button.

Answer 2

Give the frame of the button in you described snippet only.

For ex,

<button_object>.frame =
CGRectMake(textField.frame.origin.x,textField.frame.origin.y +
x,textField.size.width,textField.size.height);


Where X = the difference upto which you want to add the button after
textfield. For ex, 44 or 50 or so on..

you can assign an tag to the button as

UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom];
[btn setTag:100];
[btn addTarget:self action:@selector(moveButtonDown) forControlEvents:UIControlEventTouchUpInside];

and whenever the button is clicked the frame for the button can be changed by getting a reference of the button.In the code below i have moved down the button by 20 pixels. You can change this value to what ever you want .

 -(void)moveButtonDown
{
    UIButton *btn=(UIButton *)[self.view viewWithTag:100];
    float y=btn.frame.origin.y;
    y+=20;
    [btn setFrame:CGRectMake(btn.frame.origin.x, y, btn.frame.size.width, btn.frame.size.height)];
}

You have to modify your code by:

CGRect frame = bottomView.frame;
frame.origin.y += (tField.frame.origin.y+textField.frame.size.height + 5);

bottomView.frame = frame;
textField.hidden = NO;
