I have an button on UIT开发者_高级运维oolbar. i need to display another toolbar on clicking that button and upon same button click , it must be hide. I am able to display toolbar but how to hide the toolbar on same button click?? help me!!

Use the tag property of your button.

if(myButton.tag = 0) // means Do hide 
{
    myToolBar.hidden = YES;
    myButton.tag = 1;
}
else 
{
  myToolBar.hidden = NO;
  myButton.tag = 0;
}

How do you hide? If you use hidden: YES just change it to hidden: NO
