Question

Hi may anyone let me know how to use three buttons to use like segment control in iPhone.

Answer 1

Set tag on each button.

[button1 setTag:0];
[button2 setTag:1];
[button3 setTag:2];

Then put the same @selector method for all buttons.

Then in your button selector method do this:-

 -(IBAction)youButtonMethod:(id)sender
{
    if([sender tag] == 0)
    {
       // your first button click
    }

    else if([sender tag] == 1)
    {
       // your second button click
    }

    else if([sender tag] == 2)
    {
       // your third button click
    }
}
